Description

The alloy AlZnMgCu0,5 belongs to the aluminum materials, which achieve very high mechanical strength. With hot ageing the strength grade F 49 is attainable. This alloy is good splinter-giving machinably. The alloy is weldable with consideration of certain conditions, especially a heat influence zone with small strength appears there. One should not weld therefore if possible. A good corrosion resistance can be only guaranteed, if an appropriate protective surface layer is present. The corrosion resistance improves noticeably also by hot ageing. Roll-plating of sheet metals of this alloy e.g. with AlZn1 will support the small corrosion resistance with exhaust the high mechanical strenght fully. Thus the area of application extends noticeably. This alloy possesses well splinter-giving workability. Heat treatment for hardening: solution annealing: 470 to 480 °C, quenching in water hot ageing: 12 to 24 h at 115 to 125 °C, 4 to 6 h at 165 to 180 °C (two stage ageing) cold ageing is uncommon Application: In mechanical engineering for devices, tools. Predominantly tension-poor strained sheet metals for baseplates, head and stamp retaining plates as well as in the automobile engineering for safety-related parts and bumpers.
