ASTM GB Lightening Industry Use Pure Tungsten Wire Black / Ground Size 0.02mm
Tungsten is a lustrous and silvery white metal. The bulk metal resists attack by oxygen, acids and alkalis. Tungsten has the highest melting point of any metal.
Tungsten is used in filaments in incandescent light bulbs; it is also used in electric contacts and arc-welding electrodes. Tungsten is used in alloys, such as steel, to which it imparts great strength.
