In the chemical industry, niobium is a high-quality acid and liquid metal corrosion resistant material that can be used in the manufacture of digester, heaters, coolers, etc. In addition, tannic acid is also an important catalyst.

It is also used in the foundry industry. Its main function is to form hard carbides (good for wear resistance) and to change the shape and size of graphite sheets. It is often used in the manufacture of cylinder heads, piston rings and brake pads for automobiles. . In addition, Niobium sometimes is used with commemorative coins with gold and silver.

Niobium helps to increase the light transmission properties of the lens and is therefore also used in the manufacture of lenses for the optical industry.

Niobium can also be applied to the lighting industry, such as bismuth and 1% zirconium alloy can be used to make high-precision high-strength sodium vapor street lamp precision bracket, so that these small parts have high heat, excellent formability and sodium vapor corrosion resistance .
