Copper’s immense popularity in products made around the world requires manufacturers to develop this alloy in high quantities to meet rising demand. However, copper by itself is often not suitable for products when it is melted and cast into shape. Its soft properties require strengthening yet also elasticity so it does not become brittle. In…
Featuring 2% boron-copper and 2% lithium-copper hardeners, master alloys, deoxidizers, and degasifiers.
A deoxidizer is a compound used in a reaction to remove oxygen. These products contain one or more elements that are scavengers for oxygen decreasing the presence of dissolved oxygen in molten metal. Degasifiers can remove oxygen and other unwanted gases such as hydrogen as well.
Binary Master Alloys as Deoxidizer – Common foundry deoxidizers are Phosphorous copper, Silicon coopers, and Boron copper.
Binary Master Alloys as Degasifier – Li Copper is an excellent deoxidizer but has the added advantage to become a scavenger for other unwanted gases as well. Lithium pre-alloyed with copper is effective as a degasifier with low reactivity.
Special Belmont Degasifiers – Compound degasifiers engineered to be effective at removing unwanted gases when used in the family of alloys they name.
Applications:
Deoxidizers and Degasifiers are used to eliminate gas holes, porosity and metal oxides, while providing the benefit of increased fluidity.
Forms:
Shot, Waffle, Lumps

Lithium has the advantage of being able to combine with both oxygen and hydrogen. Used on its own, Lithium will be more of a deoxidizer. Used in a “duplex treatment”, deoxidizing first, then Lithium can be considered a degasifier now available to be a scavenger for hydrogen and other unwanted gasses. Forms: - 1 Lb. Pcs. 1" X 1" x 4"
- 3-4 Oz. Polished Pieces
- 1" x 6" x 12" Slabs
Belmont Product Code 4981 Nominal Composition: - 98% Cu
