ZL101属可热处理强的化铝－硅－镁系铸造铝合金， 该合金具奋优良的铸造工艺性能，即高的流动性， 气密性和低的热裂、疏松倾向；它还具有优良的耐大气腐蚀和抗应力腐蚀性能；焊接性能良好， 通常采用氩弧焊， 也可采用气焊、 碳弧焊、 原子焊等；切削加工性能低于铝－镁系和铝铜系合金， 刀具磨损也高于含硅量低的合金。
该合金是一种应用广泛的铸铝材料。 适用于砂型、 金属型和熔模铸造等工艺方法， 制造形状复杂、 璧厚较薄或要求气密性的承受中等载荷的各种航空零件， 如飞机结构零件、 仪器仪表附件、 发动机零件、 燃油泵壳体等。
ZL 101 is an aluminum - silicon - magnesium alloy that has strong heat treatment performance. It has good casting processibility, such has high liquidity, air tightness and low tendency of hot crack or loosening; It also has good atmospheric corrosion resistance and stress corrosion resistance; It has good welding performance, which usually adopts argon arc welding, as well as gas welding, carbon arc welding, and atomic welding, etc. Its machinability is lower than of aluminum - magnesium and aluminum - copper alloys, and tool wear is higher than that of alloy with low silicon content.
The alloy is a widely used cast aluminum material, which 1s suitable for sand mold casting, metal mold casting and investment casting Process to manufacture various medium load aviation parts with complex shapes, thin wall thickness or that require air tightness. Such as aircraft structure parts, instrument accessories, engine parts, fuel pump shell, etc.
