Rhenium-tungsten tungsten pin refers to a tungsten needle made of an alloy containing rhenium and tungsten. Rhenium and tungsten are both transition metals, and alloys can be designed to tune their hardness, toughness, and other physical and chemical properties.
1. Carbide: A combination of rhenium and tungsten may be used to make cemented carbide, where tungsten provides high hardness and rhenium can improve some properties of the alloy, such as toughness.
2. Electrode materials: Rhenium and tungsten alloys may be used to make electrode materials, especially in some high temperature and corrosive environments due to the high melting points and corrosion resistance of these two metals.
3. Other applications: There may be other special application fields, such as laboratory, medical or industrial fields, which may require tungsten needles with specific physical and chemical properties.
