HABA G-Alu340

7xxx

(AlZn5Mg1)

Sawn or milled aluminium casting plates

HABA G-Alu340 is an aluminium casting plate with significantly higher dimensional stability than naturally hardened casting plates. We achieve the persistent equal strength with a multi-stage process of heat-treating and natural aging. The material stands out for its excellent machinability and great stability.

 

APPLICATIONS

  • Base plates
  • Rotary tables
  • Table tops
  • Foam, deep-draw and sample moulds
  • Machined and engineered parts of all kinds
