80% of tellurium consumption is used in the metallurgical industry. A small amount of tellurium in steel and copper alloys can improve its cutting performance and increase hardness. Tellurium is used as a carbide stabilizer in cast iron to make the strong surface and abrasion resistance. Contain a small amount of Lead in Tellurium can improve the corrosion resistance, abrasion resistance and strength of the material, and is used as the sheath of cables.
