The correct way to store and transport aluminum sheets

1. The aluminum storage warehouse should be clean and dry, free from rain and snow. At the same time, active chemical materials (acid and alkali salts, etc.) and wet items should not be stored in the warehouse. 2. For aluminum plates and aluminum materials with high surface requirements, the surface should be oiled, but the storage conditions are good, or short-term storage may not be applied. 3. Because some aluminum plates and aluminum materials are soft, it is necessary to prevent scratches when moving. The damp aluminum plates are not easy to be smashed. It is recommended to use sunlight to make the wet aluminum plates not to be stacked. 4, the aluminum plate should not be placed directly on the ground, even if the aluminum plate itself has a film, paper bag packaging, but also the aluminum plate on the wooden pallet, wooden frame, so that the aluminum plate is not easy to be oxidized by moisture will be more conducive to ventilation. 5. The aluminum plate, aluminum and other products are rusted. After being wiped off with a cotton yarn head or a clean rag, the industrial Vaseline is added, but it is not easy to store for a long time after such treatment. 6. Aluminum plates and aluminum materials should pay more attention to avoid the erosion of rain, snow and other corrosive media during transportation.

6 ways to solder aluminum parts with electric soldering iron

 In the maintenance of radio and home appliances, it is sometimes necessary to solder small aluminum parts because the surface of the aluminum device is easily oxidized, which is difficult for beginners to solder firmly. The author refers to the welding information of aluminum parts and has been successfully tested. This paper introduces these practical methods of soldering aluminum for reference.     First, the solder is first applied to the solder joint of the aluminum part, and then the hot soldering iron is saturated and placed in the soldering place for preheating. When the temperature rises, the solder is thickened and then added with some solder and Solder, so that the solder will contain the soldering iron tip, and then use the soldering iron tip to rub the front and back of the soldering station. The friction distance should not be too large. Generally, the aluminum alloy film on the surface of the aluminum component is cut at the soldering iron tip between 3 and 5 mm. The solder joint is not able to produce a new oxide film due to the inclusion of molten tin and air, and the tin can be applied to the aluminum member of the oxide film that has just been removed. The isothermal tin is changed from a spherical shape to a flat shape, indicating that the aluminum member has been firmly bonded to the tin. At this time, the friction is stopped and the remaining flux is wiped off, and then soldered to the lead wire or other components of the tin. It is very convenient.     Second, first drop a few drops of dilute hydrochloric acid in the solder joint of the aluminum component to remove the surface oxide film, wait a while, then add a few drops of concentrated copper sulfate solution, and wait until the weld is covered with copper, wash it off with water. The excess copper sulphate solution and the hydrochloric acid solution can then be welded with a 45-75W soldering iron, which works well.     Third, take a piece of aluminum into the crucible to heat and melt, then add 2 to 5 times of tin to melt and then use, and then it is convenient to weld according to the conventional method.     Fourth, in the treatment of clean aluminum surface, coated with a solution of mercury nitrate, eat more tin with a 100w soldering iron tip, and use a soldering iron tip to rub the mercury nitrate solution on the welding surface. This can be welded firmly. But note: Mercury is toxic, it should be welded in a ventilated place, and do not use highly toxic mercury chloride.     5. The aluminum parts are welded by the earth method. The white powder of the saw glass fiber board is prepared in advance, placed on the surface of the welding surface, and rubbed with a 75w soldering iron on the welding surface until a layer of tin is attached to the aluminum surface, and then the cloth is used. The mixture of white powder and rosin is removed, and then it can be welded by a general method. The practice is simple and the welding effect is satisfactory.     It is also possible to mix rosin and iron filings, then polish the aluminum surface with sandpaper, place the rosin and iron powder on the polished surface of the soldering surface, repeatedly rub the aluminum surface with a soldering iron, and then press the general method. Smooth welding.     Finally, the sixth method, first polished the surface of the aluminum parts of the welding, and then drop a few drops of sewing machine oil, the amount of oil should be sufficient, and then use a sharp knife to scrape back and forth several times in the welding, and then use a soldering iron to solder and rosin in the welding Rubbing back and forth, tin will soon adhere to the aluminum piece firmly, this method is also simple and practical.

Brief introduction of Baodi Aluminum’s 1 Series-7 Series Aluminum Alloy

 1 series: 1060 Features: more than 99.00% aluminum, good electrical conductivity, good corrosion resistance, good welding performance, low strength, no heat treatment strengthening. Application range: high purity aluminum (more than 99.9% aluminum) is mainly used for Scientific testing, chemical industry and special applications. 2 series: Features:: Aluminum alloy containing copper as the main element. Manganese, magnesium, lead and antimony are also added for machinability. Such as: 2011 alloy, pay attention to safety protection during the melting process (will produce harmful gases). The 2014 alloy uses the sky aviation industry with high strength. The 2017 alloy is a little weaker than the 2014 alloy, but it is easier to process. 2014 can be heat treated and strengthened. Disadvantages: The tendency of intergranular corrosion is serious. Applications: Aviation industry (2014 alloy), screws (2011 alloy) and industries with higher temperature (2017 alloy). 3 series: Features: Aluminum alloy with manganese as the main alloying element, can not be heat-treated and strengthened, has good corrosion resistance and good welding performance. Good plasticity. (close to super aluminum alloy). Disadvantages: low strength, but can be strengthened by cold work hardening. It is easy to produce coarse crystal grains during annealing. Applications: Oil-conducting seamless pipes (3003 alloy) and cans (3004 alloy) used on aircraft. 4 series: mainly based on silicon, not commonly used. Part 4 is heat treatable, but some 4 series alloys are not heat treatable. 5 series: Features: mainly magnesium. Good resistance, good welding performance, good fatigue strength, no heat treatment and strengthening, only cold processing to improve strength. Applications: lawn mower handles, aircraft fuel tank conduits, body armor. 6 series: Features: mainly magnesium and silicon. Mg2Si is the main strengthening phase and is currently the most widely used alloy. 6063, 6061 used the most, other 6082, 6160, 6125, 6262, 6060, 6005, 6463. 6063, 6060, and 6463 are relatively low in the 6 series. 6262, 6005, 6082, 6061 are relatively strong in the 6 series. Characteristics: medium strength, good corrosion resistance, good welding performance, good process performance (easy extrusion), good oxidation and coloring performance. Applications: Energy tools (eg car luggage racks, doors, windows, body, heat sink, compartment casing) 7 series: Features: mainly zinc, but sometimes a small amount of magnesium, copper. Among them, super-hard aluminum alloys contain the hardness of zinc, lead, magnesium and copper alloys close to steel. The extrusion speed is slower than that of the 6-series alloy, and the welding performance is good. 7005 and 7075 are the highest grades in the 7 Series and can be heat treated for reinforcement. Applications: Aviation (aircraft load-bearing components, landing gear), rockets, propellers, aviation spacecraft.
