Tantalum Bar / Tantalum Rod (Ta Bar / Ta Rod)
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. Tantalum rod and bar are mainly used as high-temperature alloys containing tantalum, tantalum-based heat-resistant and corrosion-resistant alloy additives.
Applications:
- Used in laboratory equipment.
- Used as a substitute for platinum.
- Used in manufacturing super alloys and electron-beam melting.
