Compared with pure aluminum, adding a small amount of alloying elements to aluminum can increase the tensile strength, yield strength and durability. The most important alloying elements are silicon, magnesium, copper, zinc and manganese. Most of these alloys are co-compounds that must be finely dispersed by hot working methods before they can be cold worked.
Aging of Aluminum Alloys Many aluminum alloys undergo age hardening to improve their mechanical properties. This can be done through natural or man-made means.
Natural Aging Hardening ACUM fires the workpiece after melting, so that the A2C deposits are compressed in the solution: and then the workpiece is allowed to age at ambient temperature. During this process, the workpiece will be removed from the solidified solid body. sink out. The tension created by the aluminum lattice increases strength and stiffness. This process takes 5-8 days.
In the artificial aging hardening method, the treatment is carried out at high temperatures, so the treatment time can be shortened. For example, AMeSi alloy, after solvent fire and tempering, the aging time is 4-48 hours at 12-175. The deposition of Mp2S phase will occur in aluminum. Internal tension is created within the frets, resulting in increased strength and hardness.
Wrought Aluminum Alloys The main alloying elements of wrought aluminum alloys are copper, magnesium, zinc and. Silicon and iron affect mechanical properties and corrosion resistance, either as impurities or as alloying elements, depending on the required purity and application.
Common uses of forged aluminum alloys:
5 Mechanical engineering and mold production panels for rolled products, such as plates and strips, and electroplated products such as radiators and heat exchangers Electroplated panels for specific semi-finished products for aircraft production or decorative applications, such as trim parts and reflectors , mechanical engineering, conveyor and electronic technology applications, as well as high-strength sports and leisure products such as snowboard bindings and mountain bike gears Fiber reinforced aluminum for the aircraft and aerospace industry.
