AlMg4.5Mn

Sawn or milled aluminium casting plates,
similar: EN AW-5083 / EN AW-AlMg4.5Mn0.7

G-Alu25 is a naturally hardened aluminium casting plate which fulfils the most demanding machinability and dimensional stability requirements. The special casting process is the guarantee for the homogenous join and the vacuum tightness. HABA G-Alu25 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.

 

APPLICATIONS

  • Base plates
