Aluminum alloy by processing method can be divided into two kinds of deformation aluminum alloy and
cast aluminum alloy:
Wrought aluminum alloy can withstand the pressure, can be processed into various forms, specifications
of aluminum alloy. Mainly used in the manufacture of aviation equipment, construction and other doors
and windows, etc.. Wrought aluminum alloy is also divided into non - heat treatment - strengthening
aluminum alloy and the heat treated - type aluminum alloy. Heat treatment can not heat treatment to
improve the mechanical properties, can only through the cold processing deformation to achieve
reinforcement, it mainly includes high purity aluminum, high purity aluminum, industrial pure aluminum
and anti rust aluminum, etc.. Heat treatment strengthening aluminum alloy can be by means of quenching
and aging heat treatment to improve the mechanical properties, it can be divided into aluminum, aluminum
forging, super hard aluminum and special aluminum alloy etc.. Deformation of aluminum alloy by the
heat treatment to strengthen the classification of the main elements of the He Jing as shown in the
following table:

不可熱處理強化鋁合金(jin)
純(chun)鋁（1000系）
鋁(lv)-錳合金(jin)（3000系）
鋁-硅(gui)合金（4000系）
鋁-鎂合金（5000系）
可熱處(chu)理強化鋁合金

鋁(lv)-鎂-硅(gui)合(he)金（6000系）
鋁-鋅(xin)-鎂合金（7000系）
Casting aluminum alloy by chemical composition can be divided into aluminum silicon alloy, aluminum
copper alloy, aluminum magnesium alloy, aluminum zinc alloy and aluminium rare earth alloy, which
aluminum silicon alloy and simple aluminum silicon alloy (cannot be strengthened by heat treatment, low
mechanical properties and casting properties), special aluminum silicon alloy (can be strengthened by
heat treatment, high mechanical properties, casting properties good), casting aluminum alloy in the as
cast condition. Some aluminum alloys can be used to obtain good mechanical properties,physical properties
and corrosion resistance.
