polished tungsten rods surface: black and polished Purity:99.95%(min),Density:19.3g/cm3 Dia: 2.5-120mm Standard:ASTM

Polished/ground Tungsten rods:

Tungsten has the highest melting point of all metals and is therefore also suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability.
