ACP 7(R)
ACP 7 / ACP 7R Excellent machining properties with high demands on mechanical properties and material stability.
The precision surface machined plate ACP 7or ACP 7R, the latter with a sawn surface, is particularly suitable for applications with high demands on mechanical properties in combination with excellent machining properties. As the world‘s leading manufacturer of aluminum cast plates, with ACP 7 we have succeeded in achieving outstanding cast plate quality in the EN AW 7000 alloy range.
