Beryllium Containing Master Alloys
Beryllium copper,
beryllium nickel, and beryllium aluminum “Master
Alloys” are formulated to introduce relatively small percentage
“alloying” additions to base metal furnace melts. Producers of aluminum,
magnesium, and nickel alloys have developed alloy product chemical compositions
that require minute percent additions of beryllium to (A.) increase
the efficiency of the alloy melting and manufacturing process, and (B.)
enhance material properties such as strength, toughness, ductility,
fluidity, and corrosion resistance in the finished alloy.
IBC Advanced Alloys manufactures master alloy products of the highest purity utilizing only ultra-pure vacuum cast beryllium or 10% metallurgical grade beryllium copper master alloy input material.
