Description

AMPCOLOY® 940 is a patented alloy which meets the demands of users of the RWMA class 3 alloys without beryllium. In the industrialized countries, stricter health and safety instructions on the use of noxious elements have forced AMPCO METAL to develop this new alloy. It replaces the AMPCOLOY® 95 in practically all applications.
