Aluminium based alloys. The main alloying elements are copper, silicon, magnesium, zinc, manganese, minor alloying elements are nickel, iron, titanium, chromium, lithium, etc..
Aluminum alloy with low density, but the strength is relatively high, close to or more than high quality steel, plastic, can be processed into a variety of profiles, with good electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the use of only in steel.
Aluminum alloy is divided into two major categories: cast aluminum alloy, used in cast state; deformation aluminum alloy, can bear pressure, mechanical properties are higher than the cast state. Can be processed into a variety of forms, specifications of aluminum alloy. Mainly used in the manufacture of aviation equipment, daily necessities, construction and windows, etc..
Alloy with zinc as a base to add other elements. Precision metal parts manufacturing often with the alloy elements are aluminum, copper, magnesium, cadmium, lead, titanium, etc.. Zinc alloy with low melting point, good fluidity, easy welding, brazing and plastic processing, in the atmospheric corrosion, residual waste for recycling and remelting; but low creep strength, prone to natural aging causes size change. Melt preparation, die casting or rolling pressure. According to the manufacturing process can be divided into cast zinc alloy and zinc alloy.
The main elements of zinc alloy, such as aluminum, copper and magnesium, can be divided into two types: deformation and cast zinc alloy.
Zinc alloy composition and casting quality
Characteristics of zinc alloy
1 than the major.
2 good casting properties, can be cast in the shape of complex, thin wall of precision parts, casting surface smooth.
3 surface treatment: electroplating, spray, spray paint.
4 melt and die casting do not absorb iron, not corrosive pressure type, non stick mold.
5 good at room temperature mechanical properties and wear resistance.
6 low melting point, melting at 385, easy to die casting.
