Belmont Metals, Inc. 10% Cobalt Copper Alloy 4907A

Jewelry Alloys

Featuring Art Caster’s Brass, Beryllium Copper, Brittania, Electrolytic Copper, Everdur, Jeweler’s Manganese Bronze, Nickel-Silver, Pewters, Superdie Zinc Alloys, and White Bronze

Brass, Bronze, and White Metal alloys have been used in the manufacture of Non Precious Metal fashion jewelry for centuries. Brass & Bronze come in a wide variety of colors including, Dark Red, Yellow, and White. Belmont Special H Silicon Bronze is a Dark Warm Red Color, our Silicon Bronze Everdur is a lighter Red, our Art Casters Brass is Golden Yellow, and Silicon Brass is Yellow in color. Custome formulations can be made in heats as small as 100 lbs for trial purposes. Our White Bronze alloy is similar in color to stainless steel and takes a patina and can be custom colored.

We also have a variety of products manufactured specifically for Karat Gold Alloying. We offer Copper, Tin, Nickel, and Zinc Shot. Belmont offers a line of Virgin Grade Master Alloys including Copper, Nickel, Silicon Copper, Boron Copper, and Cobalt Copper for alloying with Gold for custom colors, specific casting charecteristics to meet most any requirement.

Belmont Copper Master Alloys are alloying elements manufactured from high purity Copper and is combined with a high percentages of one or more elements. Our alloys enable casting houses and ingot manufacturers to overcome problems associated with alloying that they may experience when working with molten metals.

Master Alloys are commonly used as additives in the manufacture of other alloys or as deoxidants, degasifiers, desulphurizing agents or of similar use in the metallurgy of non ferrous metals. A Master Alloy can be referred to as a “hardener”, “grain refiner” or “modifier”, depending on the application

There are several reasons for adding a Master Alloys to a melt, the main one being selective composition adjustment. They are used to modify the composition of the molten metal, allowing you to achieve a desired chemical specification. A second important application is for specific performance requirements. Master Alloys have the ability to change the micro-structure of a metal during casting and solidification in order to change its properties. Properties that can be modified include: castability, surface finish, electrical conductivity, mechanical strength or ductility.

The use of a Master Alloy instead of a pure metal can be for economical reasons, since certain elements will have a poor yield or create high losses when melted in pure form. Technical issues may also prevent the pure metals from dissolving completely or the required furnace temperature is too high for a basic casting operations equipment. Our Master Alloys provide the solution by dissolving quicker at lower temperatures while saving valuable time and energy.

Applications

Used to enhance properties of Copper Alloys to increase fluidity, hardness, color, ductility, and others
