Tungsten is a rare metal with high melting point, which can improve the high temperature hardness of steel.

Tungsten is a nonferrous metal. Usually people divide metals into two categories according to their color and properties: ferrous metals and non-ferrous metals.

Keep the molybdenum wire in a cool and ventilated place with low humidity, and keep the temperature at 20 ℃ ~ 25 ℃ as far as possible to avoid oxidation of molybdenum wire; Molybdenum wire may have poor verticality when it is placed for more than 6 months.

Molybdenum wire is used in profile cutting, H2 furnace, heater rod guide rod hook, mandrel, wire, lead, etc.

Molybdenum is hard, soft and tougher than tungsten. Molybdenum has high modulus of elasticity, tungsten, tantalum and only high melting point. Molybdenum plate is used in many special steels.

Mainly refers to a kind of consumables made of precious metals such as molybdenum, which move continuously with high voltage electric field in WEDM. That is to say, the fine wire which moves continuously in WEDM machine tool is called electrode wire (also called electrode), which can remove the workpiece by pulse spark discharge and cut metal forming.

The wall thickness of heat-conducting pipe is determined by using conditions, material of tube sheet, construction ability of expanding operation and welding technology of pipe end.

There are more than ten major tungsten deposits, and there are two main types in China: wolframite (tungstate of manganese and iron) and scheelite (calcium tungstate).
