Molybdenum belongs to the group of refractory metals. Refractory metals are metals with a higher melting point than platinum (1772 °C). In refractory metals, the binding energy of individual metal atoms is particularly large. Refractory metals have a combination of high melting point, low vapor pressure, high modulus of elasticity and high thermal stability. In addition, refractory metals also exhibit the typical characteristics of low thermal expansion coefficient and high density. Thanks to its mechanical and chemical properties, molybdenum is an outstanding material capable of meeting demanding requirements. Its advantages of high melting point, low coefficient of thermal expansion and good thermal conductivity make it widely used in many different industrial fields.Application
1. Aluminum wire is used in profile cutting, H2 furnace, heater rod guide rod hook, mandrel, wire, lead, etc.;
2. Silver is used in the manufacture of high temperature resistant equipment, such as brackets, guide rods, heating rods in furnaces, etc.;
3. Molybdenum wire is mainly used in high-temperature heat fields of aluminum furnaces and electronic tube sockets. Molybdenum wire is a thin silver rod, which is divided into white molybdenum wire, black molybdenum wire, sprayed molybdenum wire, and molybdenum wire for wire cutting. Molybdenum wire is often used as materials for heating high-temperature furnaces, heating screens for support materials, etc.

Properties of molybdenum:

1. The melting point of molybdenum is 2623°C, which has excellent creep resistance and can withstand higher temperatures.
2. Low coefficient of thermal expansion and good thermal conductivity

1) High melting point
2) Very low vapor pressure (this is especially important for refractory and vacuum industry applications.)
3) High physical strength at high temperature (for structural parts in high temperature environment)
4) Creep resistance (high-temperature load structural parts. High dimensional stability. For example: forging dies for large aero-engine turbine blades.)
5) High modulus of elasticity
6) Very low coefficient of thermal expansion (very important for the application of metal-ceramic structure, metal-semiconductor structure, metal-graphite structure. For example, in the LED field, the future V-LED, which is regarded as a high-power LED, will use molybdenum or molybdenum copper material as base material)
7) Excellent electrical conductivity (metal properties)
8) Excellent thermal conductivity (metal properties)
9) Selective corrosion resistance
