Master alloys and alloying additives are alloy-element concentrates, grain refiners, hardeners, deoxidants, and other agents added to a melt or metal-powder blend to produce a particular alloy, modify a melt, or alter processing characteristics. They are designed to improve processes in metallurgy by refining the final properties of different rare metals. Alloying agents and elements are used as additions to modify or produce alloys in primary metal production melts, foundry melts, and powder metal-blend manufacturing.
Applications
Major applications of copper boron alloys include:
Deoxidiser for copper.
Grain refiner for brass.
Most of the ferrochrome produced worldwide is used in manufacturing stainless steel. The chromium content present in stainless steel provides resistance to corrosion as well as gives stainless steel its customary appearance. Around 18% of chrome is used in per unit content of stainless steel. Ferrochrome powder is used in the field of powder metallurgy. Ferrochrome slag is a chemically stable substance. It is used in road construction and civil engineering as well as in the production of refractory materials.
Chromium powder can be used to repair and prevent the four pipes of the boiler, and metallurgically distribute the wear-resistant lining of the chute. The use of tubular wire surfacing with Cr3C2 will greatly increase the service life of the grinding roller.
