Tungsten Alloy Solderability Is Good

Aug 22, 2017

Tungsten alloy material is a kind of tungsten as the matrix (W content of 85-99%), and add Ni, Cu, Co, Mo, Cr and other elements of the alloy. According to the composition and application of alloy composition, W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag and other major series, the density of up to 16.5-19.0g / cm3, and It is also known as a high specific gravity alloy, it also has a series of excellent characteristics, than the major: the general proportion of 16.5-18.75g / cm3, high strength: tensile strength of 700-1000Mpa, strong ability to absorb radiation: its ability to ratio Lead height 30-40%, thermal conductivity: 5 times the die steel; thermal expansion coefficient is small: Tungsten Alloy Metals only iron or steel 1 / 2-1 / 3, good conductivity; with good solderability and processing The In view of the high proportion of the alloy has the above excellent function, tungsten alloy in the national economy and the defense industry has been widely used. The aerospace and aerospace industries are used for gyroscope rotor, counterweight and balancing materials, as well as for guiding devices and shock absorbers;

Alloy Preparation Process Flow The key to the alloy preparation process is the sintering process. Sintering temperature is generally 1400 ~ 1600 ℃, and produce liquid phase, Tungsten Alloy Metals is conducive to the damping of the alloy, sintered alloy can reach the theoretical density of 99% or more.

High density, high strength, good plasticity and machinability, good electrical conductivity and thermal conductivity, good corrosion resistance, good weldability, excellent absorption of various rays.

Tungsten alloy is based on tungsten to join other elements of the alloy. In the metal, the highest melting point of tungsten, high temperature strength and creep resistance and thermal conductivity, Tungsten Alloy Metals conductivity and electron emission performance are good, the major, in addition to a large number of used for the manufacture of cemented carbide and alloy additives, tungsten and its alloys are widely used In the electronics, Tungsten Alloy Metals electric light industry, but also in the space, casting, weapons and other departments for the production of rocket nozzles, die-casting mold, armor-piercing missile, contacts, heating and insulation screen.
