Beryllium
Free (18150) meets the mechanical requirements of RWMA Class 3
Copper.
C18000
is utilized when a combination of very good mechanical strength along with
moderate electrical and thermal electrical
conductivity are required.  C18150 is a viable substitute for C17500 and C17510
for many applications.  C18150 is a heat treatable copper
alloy.
