Product description

Product manual

Tungsten rods, tungsten rods, tungsten rods and tungsten electrodes are finished products of pure tungsten metal processed by high temperature and high pressure. The appearance is black or bright silver depending on the processing technology. Tungsten rods have the characteristics of high melting point, low thermal expansion coefficient and good thermal conductivity, and are widely used in traditional industry and military.

Application

Mainly used for drawing tungsten wires, processing ion implantation parts, manufacturing electric light sources and electric vacuum parts, used as high-temperature heating elements and high-temperature structural parts, used as electrodes in the rare earth industry, and machined into pure tungsten electrodes.

Mo-Re Target

product manual The ratio of molybdenum to rhenium: MoRe14%, MoRe41%, MoRe44.5%, MoRe47.5% Size range: thickness (0.2-20) × width (≯500) × length (≯1000), can be customized according to customer requirements Process flow: powder mixing → pressing → sintering → forging → annealing → machining → dynamic balance → vacuum degassing → packaging use A type of alloy formed by adding 14% to 47.5% rhenium to molybdenum. After adding rhenium, the ductility, welding performance and formability of the alloy can be greatly improved. Even after high temperature use, the molybdenum-rhenium alloy can still maintain good ductility Sex. Molybdenum-rhenium alloys are widely used in the electronics industry, nuclear industry and aerospace industry.

Molybdenum target

Purity specifications: 99.95%; 99.98% Density: ≥10.10g/cm3 Organization: average grain size is less than 150 microns, typical target and surface structure

Molybdenum wire

Molybdenum wire has a high melting point, good winding performance and mechanical processing performance, and good wear resistance. It is often used in the manufacture of winding core wires, brackets, lead wires and heating wires for various electric light sources. Molybdenum wire can also be used for high-temperature spraying to improve the wear resistance of automobile and other mechanical wear parts. Our company adopts special processing technology to produce molybdenum wire special for wire cutting with high strength, good discharge performance, high surface finish, fast cutting speed, long life and low wire tightening frequency. It is mainly used for various non-ferrous metals, steel and magnetism. Material of wire cutting wire.

High purity molybdenum rod/molybdenum bar /molybdenum wire

Metal molybdenum has many excellent properties: high melting point, high creep resistance and low thermal expansion. In the absence of oxygen, molybdenum has quite good corrosion resistance to various acids, metal liquids and molten glass. Within 1100°C, molybdenum is relatively stable in hydrogen, ammonia and nitrogen. After rolling, forging and drawing, the actual density of molybdenum rods can reach or approach the theoretical density, the strength, plasticity, and toughness are further improved, and the forming performance is improved. Therefore, it is widely used as high-temperature furnace components, glass furnace electrodes, electronic tube components, etc. .
