AlMg4.5Mn

Milled rolled aluminium plates: EN AW-5083 / EN AW-AlMg4.5Mn0.7

HABA Alu28 is an annealed, naturally hard rolled plate with a precisely milled surface. The plates have an excellent parallelism, are easy to machine and dimensionally stable. HABA Alu28 is well suited for machining. Use tools for working aluminium with a cutting speed >2000 m/min. Threads are produced favourably with thread moulders.

 

APPLICATIONS
