Tantalum (Ta) is a dark blue-gray metal that is very heavy, ductile and hard and has high corrosion resistance

Tantalum (Ta) is a dark blue-gray metal that is very heavy, ductile and hard and has high corrosion resistance. Tantalum is especially resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluouric acid. It has the fourth highest melting point of all metals and is able to form extremely thin and protective oxide layers for high-quality capacitors, making it an excellent material for lumps.

Tantalum Used in Chemical IndustryÂ
Tantalum is an excellent corrosion resistance material. Its corrosion resistance is better than Zirconium and can be compared with glass.

Except fluorine, hydrofluoric acid, acidic solution containing fluoride ion, nordhausen acid and strong alkalis, tantalum can't rot in most media.

Tantalum and its alloys like Ta-2.5W,Ta-7.5W,Ta-10W,Ta-40Nb and so on. It can bear high-temperature and mineral acids' erosion better than many materials.

Tantalum Used In Aerospace Industry
Tantalum especially tantalum alloys like tantalum tungsten alloy, tantalum and tungsten zirconium alloy, tantalum hafnium alloy and other bar materials can be used for making high-temperature resistance materials and controlling, conditioning parts in supersonic aircraft, rocket, missile. Tantalum tungsten alloy's Ta-10W can be used under 2500℃.
