Master alloys

Master alloys are combinations of base metals with one or more elements, designed to improve specific properties in alloys during metal production. They are essential in refining and enhancing materials used in industries like aerospace, automotive, and electronics. The leading producers of master alloys are the United States, China, and Russia. Master alloys are mainly used in steel production, aluminium alloys, and specialised applications.

Metalshub provides producers and consumers of master alloys with a software solution to improve the way they buy or sell it. Our software connects over 2,000 companies in a joint trading network. This allows sellers to discover new buyers of master alloys and buyers to discover new suppliers of master alloys.

For buyers, Metalshub’s Procurement Solution allows steel mills, foundries, and other consumers to digitalise their procurement process in order to increase sourcing efficiency, ensure compliant buying, and take data-driven decisions. For sellers, Metalshub’s Sales Solution allows producers, traders, and other sellers to digitalise their sales process, manage inventory, and optimise their sales book.

Master alloys are produced by melting base metals like aluminium, copper, or titanium and combining them with specific alloying elements such as vanadium, niobium, or boron. This process is performed in controlled environments to ensure uniform distribution of the alloying elements. The resulting master alloy is then cast into ingots or granules for use in various industries, including steelmaking.

Master alloys are primarily used in the steelmaking industry (~50%) to enhance specific properties such as strength and corrosion resistance. They are also used in aluminium alloy production (~30%) to improve castability and mechanical properties. In the aerospace industry (~15%), master alloys like titanium-aluminium and nickel-based alloys are essential for manufacturing high-performance components.
