HABA Alu28
3.3547
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. Threads are produced favourably with thread moulders.
APPLICATIONS
- Base plates
- Rotary tables
- Side walls
- Foam and sample moulds
