ALPLAN7075 precision plates combine a good dimensional stability with high mechanical strength. Both the outstanding flatness and the low roughness of the surfaces, protected by a plastic film, make surface milling by the end user superfluous. This combination of properties enables significant cost savings in machining. Applications include reference plates, machine housings, transport tables, jigs, robot arms
