Hello from Argentina,
Dears, we made some As-Cu alloys and it was easy. Depending on the As and
Sb concentrations and take into account the differences in fussion
temperatures, but if you strongly wrap the As and Sb with Cu sheets you
could reduce the evaporation it is preferable to make a mother alloy
richer in As and Sb and then adding copper you might obtain the
composition you like to.
Good luck.
