Buderus Edelstahl >>> 7075Aluminium alloy (Al Zn Mg CU 1.5) TEMPER Hardened T651Chemical analysis (weight %) Min. Max. Performance properties and aptitudes : Essentially intended for mechanical applications, this alloy is stronger than 2017 A (AU4G). Its excellent mechanical properties are closer to those of semi-hard structural steel, with considerably less weight, very good machinability and excellent corrosion resistance. Good dimensional stability for machining, good a nodisability but very poor weldability (acceptable for resistance welding). Good mechanical strength at heat of up to max. 100-120°C Cutting-tool shoes, column blocks, die holders, prototype moulds, moulds for elastomers or injection of plastic materials, assorted mechanical parts, structural elements of special machines, machining fixtures, riveted and bolted constructions exposed to considerable loads.
