The factors affecting the gas content of 6061 aluminum plate.

The gettering property of a metal is determined by the ability of the metal to combine with the gas. The 6061 aluminum plate metal has a different binding force to the gas, and the solubility of the gas in the metal is also different.

Metals and alloys with high vapor pressure can reduce the gas content due to evaporation adsorption. Alloying elements that have a greater binding force to the gas increase the solubility of the alloy. In contrast to the elements with less binding force to the gas, increasing the solidification temperature range of the alloy, especially the element which lowers the temperature of the solidus line, tends to cause pores and looseness in the ingot.

Copper, silicon, manganese, and zinc all reduce the gas solubility in aluminum alloys, while titanium, zirconium, and magnesium are opposite.

Effect of temperature on casting of aluminum alloy profiles such as 6061 aluminum plate

The higher the temperature of the molten metal, the faster the thermal movement of the metal and gas molecules, and the faster the diffusion rate of the gas inside the metal. Therefore, in general, the solubility of a gas in a metal increases as the temperature increases.

Effect of pressure on casting of aluminum alloy profiles such as aluminum rods

Pressure and temperature are two interrelated external conditions. Pressure factors also have a significant impact on the ability of metals to absorb gases. As the pressure increases, the gas solubility also increases.

Other factors in the casting of aluminum alloy profiles such as aluminum rods

Due to the presence of an oxide film on the surface of the metal melt and its density, it hinders the diffusion of gas into the interior of the metal, which greatly slows down the dissolution rate. If the oxide film is destroyed, it will inevitably accelerate the metal absorption of gas. Therefore, any operation that destroys the oxide film on the surface of the melt during the casting process is disadvantageous.

For any chemical reaction, the time factor is always beneficial to the continuous progress of a reaction, eventually reaching its saturation state in which the gas dissolves in the metal. Therefore, the longer the exposure time in any case, the more inhalation. In particular, exposure of the melt to high temperatures for extended periods of time increases the chance of inhalation. During the smelting process, the 6061 aluminum plate always strives to shorten the smelting time to minimize the gas content of the melt.

Advantages of Aluminum Panels in the Shipbuilding Industry

The lightweight development in the shipbuilding industry has promoted the progress of aluminum plates in the shipbuilding industry. The materials commonly used in the traditional shipbuilding industry are aluminum plates and glass reinforced plastics. In the past few years, FRP has occupied most of the market in the shipbuilding field with price advantage, However, the strength of FRP is low, once damaged, the maintenance cost is high. Moreover, the price of aluminum sheet has been reduced in recent years, which has reduced the cost gap between aluminum and glass sheets. Therefore, more and more people are choosing to build aluminum sheets. The advantages of aluminum sheet shipbuilding are:

1. The aluminum plate has high strength and light weight (half the weight of the FRP), and the aluminum plate shipbuilding is 15%-20% lighter than the traditional material.

2, Aluminum plate corrosion resistance is good, aluminum plate is a non-ferrous metal plate, has good corrosion resistance, can resist seawater corrosion, increase service life.

3. The aluminum sheet has good formability and can be welded. With the improvement of domestic welding technology, the popularization of aluminum sheet welding technology has promoted the development of the domestic aluminum sheet shipbuilding industry.

Under the many advantages of aluminum plate shipbuilding, the ship can achieve higher driving speed and longer service life. This year, Baodi 5052 aluminum plate, 6061 aluminum plate, 7075 aluminum plate and other aluminum alloys are widely used in large-scale surface ships, ocean-going merchant ships, passenger ferries, transportation boats, and other high-speed ships.

Application of aluminum panels in lightweight vehicles

    Aluminum alloy sheet is not unfamiliar in the field of contemporary lightweight vehicles. Automotive aluminum will become a new growth point for aluminum panels in the future with the development of lightweight vehicles.

The light weight of the aluminum plate is one of the larger quality of the product itself.The body weight consumes about 70% of the fuel under normal circumstances. Therefore, the primary problem of reducing the fuel consumption of the car is to make the car lighter. The main material of car is aluminum plate.Ford released the 2015 F-150 model, 97% of the body is made of aluminum, which is 320 kg less than the previous steel body model, and fuel efficiency is increased by 30%.

The aluminum plate has high strength, corrosion resistance, good elasticity, excellent impact resistance, good processing and high recyclability, which makes the aluminum plate develop rapidly in the automotive field. At present, the application of aluminum plates in the automotive field mainly lies in auto parts: including automobile hoods, doors, tailgates and side panels.

How to ensure the Excellent Mechanical Properties of 6061 Aluminum Plate?

 The mechanical properties of 6061 aluminum sheet is often the key factor to judge the quality of aluminum sheet.How can we guarantee the excellent mechanical properties of 6061 aluminum sheet in the production ?

First:Qualified Chemical Composition

It must be ensured that the composition index of cast aluminum meets the national standard requirements before extrusion,the content of Si and Mg has an important influence on its mechanical properties especially . We know that if mg2si, of 6061, is not able to form enough mg2si, then the subsequent solid solution treatment, quenching and aging are no longer of any significance and can not be strengthened.

Second: Strict process control during extrusion is the key to good mechanical properties

Due to the limitations of actual conditions, employees are often difficult to grasp the control of the process in the production process, often do not realize the importance of the process, the temperature, speed and other control is not strict, resulting in product aging, mechanical properties Not qualified.

If our bar temperature is not enough,there is no guarantee that the reinforcement Mg2Si will completely dissolve into the aluminum matrix when the alloy does not reach the temperature of solution treatment during extrusion, so that it cannot strengthen the role; if our bar temperature too high, it will not only destroy the alloy structure, but also often cause problems such as tearing and poor surface quality in the extrusion process because the temperature is too high.

The strengthening phase Mg2Si dissolved in the aluminum matrix cannot be stably retained in the matrix if our cooling effect is not good and the alloy cannot be cooled rapidly after solution treatment.

With the decrease of temperature, mg2si precipitates slowly in the matrix with the decrease of solubility, so that the mechanical properties of the matrix can not be guaranteed after aging. If the solid solution treatment can make the profile cooling rapidly, then the strengthening material will be too late to precipitate, will remain in the matrix, thus can play the role of strengthening after aging. Therefore, the control of temperature and other processes is the key.

Third: the correct aging process is a guarantee of good mechanical properties

The main purpose of profile aging is to act as a dispersion strengthening effect, so that the strengthening phase Mg2Si dissolved in the matrix is uniformly and diffusely distributed into the matrix during the aging process and play a strengthening role.The mechanical properties are certainly not guaranteed if our temperature and time are not well grasped and the purpose of aging cannot be achieved in the process of aging.

Aluminum Plate State (H) Details

 The state of the aluminum plate H state is a common state, which means that the aluminum plate has been subjected to work hardening treatment to improve the strength. In the five basic states of the aluminum plate (F, O, H, W, T), the H state is a state in which we often come into contact with and have a large number of subdivisions. The aluminum plate of the same specification and the same grade has different subdivision states. Performance will vary greatly.

H state representation

H is followed by 2-3 digits, indicating the subdivision state of the H state, and the state of the 2 digits is the most common.

The first digit indicates the processing status of the aluminum plate:

H1: Work hardened state, indicating that the aluminum plate has not been heat treated, and the required strength is obtained only by work hardening.

H2: Work hardening and incomplete annealing state, indicating that the aluminum sheet has been work hardened and the strength exceeds the specified requirements. After incomplete annealing, the strength of the aluminum sheet is reduced to the standard strength.

H3: Work hardening and stabilization treatment state, indicating that the aluminum plate is subjected to heat treatment during heat treatment or processing, and the mechanical properties are stable. H3 is only suitable for aluminum sheets that are naturally aged at room temperature.

H4: Work hardening and painting treatment state, indicating that the aluminum plate is subjected to painting treatment after the work hardening, resulting in an incompletely annealed aluminum plate.

The second digit indicates the strength of the aluminum sheet and the degree of work hardening:

Generally, the degree of hardening is divided into 8 grades, 1 low, 8 high, and 9 represents a superhard state which is higher than Hx8 work hardening.

  E.g:

The H18 state indicates that the aluminum plate has only been subjected to work hardening without being heat-treated, and the strength is such that the aluminum plate has a large strength.

The H24 state indicates that the aluminum plate undergoes incomplete annealing after work hardening and the strength is moderate.

The H32 state indicates that the aluminum sheet is subjected to low-temperature annealing after work hardening, and the state is stable, but the strength is lower than that of the aluminum plate of H24.

The meaning of the three-digit status:

H111 state: It is suitable for products that have undergone appropriate amount of work hardening after final annealing, but the degree of work hardening is not as good as H11.

H112 state: Suitable for hot-rolled sheet free-formed, hot-formed products.

H116 state: Applicable to products made of 5-series alloy with magnesium content ≥4.0%. These products have specified mechanical properties and resistance to flaking corrosion.

The Difference between 1060 Aluminum Plate and 6061 Aluminum Plate

1060 aluminum plates and 6061 aluminum plates are commonly used in daily use among the aluminum plates, but the hardness, characteristics, range of use and price are greatly different due to the difference between the two plate materials:

1060 aluminum plate belongs to 1 series aluminum plate or pure aluminum plate, the aluminum content is over 99.6%. The production process of 1060 aluminum plate is single, the technology is mature and the price is low. The aluminum plate has moderate hardness, high corrosion resistance, thermal conductivity and electrical conductivity and used in traffic signs, billboards, chemical equipment, sheet processing, deep drawing and spinning concave vessels, heat exchangers, kitchen utensils, etc. It is one of the commonly used aluminum plate grades in the industry.

6061 aluminum plate is a representative product of aluminum silicon magnesium alloy aluminum plate.6061 aluminum plate has certain wear resistance and rust resistance because it contains silicon magnesium. It can be welded, has good oxidation effect and good hardness.It is mainly used in trucks and ships, trams, mechanical parts, precision machining, etc. The current mold delivery, mechanical manufacturing is mainly 6061 aluminum plate.

The hardness of 1060 aluminum plate and 6061 aluminum plate is very different. The hardness of 1060 aluminum plate is moderate, which can adapt to common processing conditions, such as bending. The hardness of 6061 aluminum plate is better, and the 6061 aluminum plate is mainly medium-thick aluminum plate (6mm-100mm). ).

Therefore, 1060 aluminum plate and 6061 aluminum plate are still very different. Users must choose their own product grades before purchasing. In addition to 1060 and 6061, Baodi manufacturers also have 1100, 2A12, 3003. 5052, 7075 and other products, complete brands, large inventory, can be tailored to meet the needs of different customers, and, Baodi has branches in Yantai, Qingdao, Weifang, Dalian and other places to meet the shipping requirements across the country Welcome to purchase, Baodi head office contact information:+86-535-6430103
