Tungsten Alloys Are Widely Used In Aerospace And Other Industries

Jul 19, 2017

According to its composition, tungsten alloy can be divided into W-ni-cu, W-ni-fe two series and W-NI-CR, W-ni-mo, W-ni-co and other alloys.

Tungsten alloy material is a kind of tungsten matrix (W content 85-99%), and added Ni, Cu, CO, MO, CR and other elements of alloy. According to the characteristics of alloy composition and use of W-ni-fe, W-NI-CU, W-co, W-WC-CU, W-ag and other major series, its density is as high as the 5-19.0G/CM3, Tungsten Alloys and is known as a highly specific alloy, it also has a series of excellent characteristics, than the major: the general proportion of the total. 5-18.75g/cm3, high strength: Tensile strength is 700-1000mpa, absorption ray ability is strong: its ability than lead high $number, The thermal conductivity is large: 5 times times of the die steel, Tungsten Alloys the coefficient of thermal expansion is small: only iron or steel 1/2-1/3, good conductive performance, good solderability and processability. Since the high gravity alloy has these excellent functions, it is widely used in aerospace, aviation, military, oil drilling, electrical instrumentation, medicine and other industries.

Because of the excellent function of tungsten alloy, Tungsten Alloys it is widely used in aerospace, aviation, military, oil drilling, electrical instrumentation, medicine and other industries.

Medical tungsten Alloy Ray shielding material series: 1, tungsten alloy grating blades, 2, tungsten alloy protective tank-used for medical radiation shielding wall, shielding needle-for medical radioactive liquid shielding, tungsten alloy storage-used for storage of radioactive material tanks, boxes and other containers. 3, Collimator--Used in medical linear accelerator and nuclear technology application of Tungsten alloy Series detection container system collimator; Co60 other radiation shielding.

Electrical Materials Series: EDM electrodes and resistance welding electrodes, Tungsten Alloys high specific electrical contacts, air circuit breaker contacts.

Military series: Sabot, submunition, Ball, rod, square particle, cylinder, other tungsten alloy electric upsetting block, the application of tungsten alloy in nuclear technology.

Tungsten alloys are high temperature resistant components used in aerospace industry. The tungsten-rhenium alloy was studied. The smelting and forming technology of tungsten has also been studied tungsten ingots were obtained by using arc and electron beam smelting, and some products were made by extrusion and plastic processing, Tungsten Alloys but the grain size of the smelting ingot was coarse, the plasticity was poor, the processing was difficult, and the yield was low, so the smelting-plastic processing technology failed to become the main production means. In addition to chemical vapor deposition (CVD method) and plasma spraying can produce very few products, powder metallurgy is still the main means of manufacturing tungsten products.
