Lithium Copper

Featuring 2% Lithium Copper for use as a deoxidizer and degasifier for copper and nickel-base alloys in a variety of forms

Belmont 2% Lithium Copper has gained recognition in recent years as one of the best deoxidizers and degasifiers for pure copper and copper and nickel-based alloys. It is especially useful for pure copper castings since it does not reduce conductivity. Other deoxidizers reduce conductivity drastically. The production of copper castings with well over 90% conductivity is possible when the proper melting and deoxidation procedures are used.

Belmont 2% Lithium Copper is a solid piece of metal in alloy form which readily dissolves In the molten metal without reaction or disturbance. This is not always the case with pure Lithium encased in a copper cartridge or tube, which may pick up moisture.


2% Lithium  Copper is used to eliminate gas holes, porosity and metal oxides while providing the added benefit of increased fluidity.
