Copper is one of the world’s oldest known commodities and the world’s third most widely used metal, after iron and aluminum, with an annual production of around 20 million tonnes.
Copper is corrosion-resistant, and is an excellent conductor of electricity and heat. It is extensively used in electrical cables.
Zinc is the fourth most common metal in use with an annual production of about 13 million tonnes.
Major applications of zinc include galvanizing (55%), alloys (21%), brass and bronze (16%).
Nickel resists corrosion and is used to plate other metals to protect them.
Its main use is in making alloys such as stainless steel. We trade registered nickel in plates and briquettes. Beside the registered nickel, we also trade unregistered nickel as well as ferronickel.
Tin resists corrosion from water and is used as a protective coat for other metals. About half of tin produced is used in solder.
The rest is divided between tin plating, tin chemicals, brass and bronze.
Lead is a bright, soft, silvery metal with a very slight shade of blue in a dry atmosphere.
Lead is used in building construction, lead-acid batteries, bullets and shot, weights, as part of solders, pewters, fusible alloys, and as a radiation shield.
Aluminum is a silvery-white, soft, nonmagnetic, ductile metal and it’s the third most abundant element in the Earth's crust (after oxygen and silicon).
Aluminum is remarkable for the metal's low density and its ability to resist corrosion. Aluminum and its alloys are vital to the aerospace industry and important in transportation and structures, such as building facades and window frames.
