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

Forms
