What is a wrought aluminum alloy?
Wrought roaluminum alloy is an aluminum alloy whose structure and shape are changed through stamping, bending, rolling, extrusion and other processes. Ingots are made by melting method, and then subjected to metal plastic deformation processing to make various forms of aluminum alloys. There are aluminum alloys that can be strengthened by heat treatment: including hard aluminum alloys, super-hard aluminum alloys, forged aluminum alloys; and aluminum alloys that cannot be strengthened by heat treatment. Mainly all kinds of rust-proof aluminum alloy. Widely used in aviation, automobile, shipbuilding, construction, chemical industry, machinery and other industrials.
Type of wrought aluminum alloy
(1) According to its performance and use characteristics, it can be divided into: rust-proof aluminum alloy, hard aluminum alloy, super-hard aluminum alloy, forged aluminum alloy and special aluminum alloy.
(2) According to the sensitivity to heat treatment, it can be divided into two categories: heat-treatable-strengthened aluminum alloys and non-heat-treatable-strengthened aluminum alloys.
Disadvantage
Generally, aluminum alloys for structural use belong to the heat-treatable strengthening category. In order to ensure good process plasticity, the structure should be dominated by aluminum-based solid solution. So alloying is limited by process plasticity.
Manufacturing technics
Wrought aluminum alloys are usually made into semi-finished products such as plates, strips, pipes, bars, boxes, profiles and forgings by metallurgical plants through pressure processing methods such as rolling, extrusion, forging and drawing.
Applications of wrought aluminium alloy
Wrought aluminium alloy occupies a major position in the materials used in aviation and aerospace products. Such as: aircraft skins, main beams, frames, strips, ribs, landing gear parts, ducts, rivets and engine blades, impellers, compressor discs, casings, press fittings, propeller blades, actuator parts, etc. Deformed aluminum alloys are also widely used in shipbuilding and construction industries
