Like tungsten, molybdenum is a refractory rare metal with a melting point of 2620 ° C. The bonding force between atoms is extremely strong, and the coefficient of expansion is small, the conductivity is large, and the thermal conductivity is good.
On July 10, the Ministry of Natural Resources held a press conference on the 2017 National Mineral Resources Reserves. At the meeting, in 2017, China's metal minerals found a general increase in resource reserves, of which tungsten ore increased by 1.4%.
China's cemented carbide ball and drill has large production capacity and global competitiveness. Its production capacity still has room for expansion. The domestic and international markets have good prospects.
Molybdenum wire has high melting point, high strength and high modulus of elasticity, low expansion coefficient, low vapor pressure, good electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in lighting appliances, vacuum devices, machining and spraying.
Carbide nozzle plays an important role in the high-pressure abrasive jet fot oil drilling. It has high hardness, high strength and excellent wear and corrosion resistance.
A few days ago, Applied Materials, the world's largest semiconductor equipment manufacturer, said that it is expected to lift the main bottleneck of the wafer process at 7nm and below, and replace the tungsten and copper with cobalt metal.
Molybdenum is an essential trace element for the human body, animals and plants. It is made of silver-white metal and is hard and tough. In fact, human body contains molybdenum in various tissues, and the total amount in the human body is 9mg
Rare elements are the general term for the elements in nature, which are sparsely populated, sparsely distributed, and rarely used by humans. They are often used to make special metal materials and are critical materials in the industrial fields of aircraft, rockets, and atomic energy.
Hot runner injection molding is a method of obtaining various plastic products by high-pressure injection of molten plastic material in a hot runner into a mold cavity, cooling and solidifying. Hot runner injection molding has the advantages of high production speed, high efficiency etc.
Molybdenum wire is made of precious metals such as molybdenum. Pure molybdenum wire is used for winding wire cores, brackets, lead wires, heating elements, molybdenum foil tapes, and auto parts spraying. Molybdenum wire is used to wind wire core glass seals, as well as molybdenum foil strips etc.
