AlMg4.5Mn0.7
Milled aluminium cast plates, similar: EN AW-5083 / EN AW-AlMg4.5Mn0.7
McBasic is a naturally hardened casting plate with good machinability and dimensional stability. Ideally suited for price-sensitive products in larger quantities. McBasic 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
- Rotary tables
- Side walls
