From Brokermet Metals and Ferroalloys we supply high purity copper nuggets for the foundry and steelworks, as an alloying additive.
Purity:> 99.99% Cu
We also supply copper shot for the foundry and steelworks, as an alloying additive. Purity:> 98% Cu The main usefulness of copper in steel casting is that it improves the resistance to corrosion of certain carbon steels, used in the construction of large metal structures. It also allows alloys to be hardened by precipitation, improving tensile strength and yield strength.
Generally, copper is usually used in amounts of 0.40-0.50% by weight of the steel. In the iron foundry the Copper is added in the bucket or in the furnace, to reduce the cooling, to refine the graphite and to increase the fluidity.
