Copper is an eternal metal, it can be recycled over and over again with virtually no detrimental effect on its properties. With it we can form alloys with more freedom than most metals and with a wide variety of alloying elements. Copper is the third most used metal in the world, behind iron and aluminum.
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.
Copper is used both with a high level of purity, close to 100%, and mixed with other elements. The cigar is mainly used in the manufacture of electrical cables.
Electricity and telecommunications.
Copper electrical cable.
Copper is the non-precious metal with the best electrical conductivity, together with its ductility and mechanical resistance, which have made it the most widely used material for manufacturing electrical, industrial and residential cables. Copper conductors are also used in electrical equipment such as generators, motors, and transformers.
The deployment is copper in most telephone cables, which also allow access to the Internet. Except for fiber optics and wireless systems that allow more data at a higher speed. On the other hand, its use in computer and telecommunications components which contain copper to a greater or lesser extent is essential, for example in its integrated circuits, transformers and internal wiring.
Copper is used in automobile and truck components, especially in radiators (thanks to its high thermal conductivity and corrosion resistance), brakes and bearings, as well as naturally in cables and electric motors. A small car contains a total of around 20 kg of copper, raising this figure to 45 kg for larger ones.
Large amounts of copper are used in trains in trains: 1 - 2 tons in traditional trains and up to 4 tons in high-speed trains. In addition, the catenaries contain about 10 tons of copper per kilometer on high-speed lines.
Not forgetting the hulls of the ships that include copper and nickel alloys to reduce fouling caused by marine fauna.
Its use appears in a large number of different and varied components of all types of machinery, such as bushings, bearings, trims, etc. It is part of the jewelry elements, light bulbs and fluorescent tubes, boilermaking, electromagnets, coins, wind musical instruments, microwaves, heating and air conditioning systems.
