High Quality ASTM B386 TZM Molybdenum Bar Rod
Product Description
Molybdenum is similar to tungsten, with a melting point of 2620℃, slightly lower than tungsten. The elongation capacity is better than tungsten, so it is more suitable for producing thin wires. Molybdenum is transformed into TZM by using small amounts of extremely thin carbides, containing more than 99.2% up to 99.5% of Mo, 0.50% and 0.08% of titanium, zirconium and carbide. TZM is more resistant to pure molybdenum and has a higher re- crystallisation temperature and better sliding resistance. The recommended operating temperatures are between 700 and 1400℃.
Characteristics and features
Its features are high resistance at high temperatures and good thermal conductivity, the TZM alloy is used to produce mould parts for gravity casting and die casting of aluminum castings or those subject to erosion by liquid metal. TZM matrices are also used in the extrusion of Copper alloys.
The molybdenum TZM possess advantages of high melting point, high strength, high elastic modulus, low linear expansion coefficient, low vapor pressure, good electrical and thermal conductivity, strong corrosion resistance and good high temperature mechanical properties.
Application
TZM product is used in high temperature applications involving strong mechanical stresses, for example in forging tools. The TZM alloy product is used to produce mould parts for gravity casting and die casting of aluminum castings or those subject to erosion by liquid metal.
Additionally molybdenum TZM high quality items are often used to manufacture electric vacuum devices and Electric light source items, it is also suitable for processing ion implantation parts. The molybdenum TZM material can be processed as an electrode in a furnace in glass and refractory fiber industry. It works in a glass Melt at 1300℃ and has good performance and long service life. TZM rods can also be used in hot runner systems to prepare various types of hot nozzles and hot runners.
