1) Remark: G-MgAl9Zn1 commercial name: AZ 91 - high values for tensile strength an 0,2%-proof strength - homogenised and hot hardened - good sliding properties, weldable - for complex casts with thin walls - good strength without heat treatment aup to 110 °C - excellent machinable - good cushioning properties - no embrittlement at low temperature - special procedure for smelting, casting, welding and polishing, because its oxidising affinity of melted Mg and Mg-swarfs Application: - for cast pieces with high shape stability and high yield stress
