G-AlMg3 is a naturally hardened aluminium casting plate which fulfils the most demanding machinability and dimensional stability requirements. G-Almg3 is excellent suited for decorative and technical anodizing. The special casting process is the guarantee for the homogenous join and the vacuum tightness.
HABA G-AlMg3 is well suited for machining. The chippings are short and break well. Use tools for working aluminium with a cutting speed >2000 m/min. Threads are produced favourably with thread moulders.
