Characteristics of aluminum alloy

Aluminium alloy density is low, but intensity is higher, be close to or exceed high grade steel, plasticity is good, can be machined all sorts of profile, have excellent conductance, conductance is hot sex and fight corrode sex, the industry is used extensively, usage is next only to steel.Some aluminum alloys have good mechanical properties, physical properties and corrosion resistance by heat treatment.Hard aluminum alloy is AI - Cu - Mg system, generally contains a small amount of Mn, heat treatment strengthening.It is characterized by high hardness but poor plasticity.Superhard aluminum belongs to al-cu -- Mg -- Zn system, which can be strengthened by heat treatment. It is the aluminum alloy with the highest strength at room temperature, but poor corrosion resistance and fast softening at high temperature.Forged aluminum alloy is mainly al-zn -- Mg -- Si series alloy, although a variety of elements are added, but the content is small, so it has excellent thermoplastic, suitable for forging, it is also called forged aluminum alloy.
