Product Description

Application of Cast Aluminum Zinc (Al-Zn) Alloy

For Al-Zn alloy, due to the high solubility of Zn in Al, the strength of the alloy can be significantly improved when the mass fraction of Zn is more than 10% in Al. Although this type of alloy has a large natural aging tendency and can obtain higher strength without heat treatment, the disadvantage of this type of alloy is poor corrosion resistance, high density, and prone to hot cracking during casting. Therefore, this type of alloy is mainly used to manufacture die-casting instrument housing parts. The characteristics and applications of common cast Al-Zn alloys are as follows:

(1) ZL401 alloy ZL401 alloy has medium casting performance, small shrinkage cavity and hot crack tendency, good welding performance and machinability, high strength in as-cast state, but low plasticity, high density and poor corrosion resistance. ZL401 alloy is mainly used for various pressure casting parts, the working temperature does not exceed 200 degrees Celsius, and the structure and shape of the automobile and aircraft parts are complex.

(2) ZL402 alloy ZL402 alloy has medium casting performance, good fluidity, moderate air tightness, hot crack resistance, good machinability, high mechanical properties and impact toughness in as-cast state, but high density, melting The process is complex and is mainly used in agricultural equipment, machine tools, ship castings, radio devices, oxygen regulators, rotating wheels and air compressor pistons.
