The deoxidation of copper alloys involves removing the oxygen using a chemical process, usually other metals. As the oxygen and other gases are removed from the metal, certain properties are either enhanced or decreased. For example, when Phosphor is added to bronze alloys, it reacts by removing the oxygen content from the metal which can…
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.
Deoxidizers and Degasifiers are used to eliminate gas holes, porosity and metal oxides, while providing the benefit of increased fluidity.

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:

Custom alloys can help streamline production Although custom alloys often are associated with new and advanced applications, they also can solve real-world production problems. For more than a century, Belmont Metals, based in Brooklyn, New York, has been working collaboratively with its customers to create materials that can improve their manufacturing processes. Coming up with…
Master alloys help copper shine Red metals have played an important role in many cultures, including those of the ancient Egyptians and Romans, who crafted tools, cookware, dishes, mirrors and razors out of copper. Modern uses for copper include electrical, heating/cooling applications, fluid handling and plumbing applications, as well as an increasing demand for the…
Create materials that meet specific needs by adding master alloys to the mix It’s important to choose the right materials for a job. Using inferior or unsuitable materials can make completing a project more difficult or even derail it entirely. In the metals industry, combinations of metals, called alloys, are generated to meet the specific…
