Tungsten Alloy Has Good Solderability


Tungsten alloy 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.

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 by the world Called 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 higher than the lead 30-40%, thermal Coefficient: 5 times the mold steel; thermal expansion coefficient is small: only iron or steel 1 / 2-1 / 3, good conductivity; with good solderability and processing. In view of the tungsten alloy has the above excellent function, it is widely used in aerospace, aviation, military, oil drilling, Tungsten Alloys electrical instrumentation, medicine and other industries.

Medical tungsten alloy ray shielding material series: 1, tungsten alloy grating blades; 2, tungsten alloy protective tank - for medical radiation shielding wall; shielded needle - for medical radiopharmaceutical shielding; tungsten alloy memory - with In the storage of radioactive substances such as cans, Tungsten Alloys boxes and other containers. 3, collimator - for the medical linear accelerator and nuclear technology applications tungsten alloy series detection of the container system collimator; Co60 other radiation shielding.

Electrical materials series: EDM electrodes and resistance welding electrodes; Tungsten Alloys high specific gravity electrical contacts, air circuit breaker contacts.

Military series: armor piercing; bullet, ball, stick, square grain, cylinder, other tungsten alloy electric forging block, nuclear technology application tungsten alloy.

The tungsten alloy material is processed by tungsten powder sintering and post-treatment. Tungsten material is a very high temperature of the metal material can be used for incandescent tungsten wire production, after treatment of tungsten alloy and raw materials still have the same high temperature performance, Tungsten Alloys tungsten alloy in more than four thousand degrees of high temperature will begin to melt, This is the unbearable temperature limit of other materials. Turbine engine is a high-performance engine, generally used for aviation rocket propulsion. The transmitter uses liquefied gas fuel, the maximum temperature in the combustion chamber can reach 3700 degrees, Tungsten Alloys only the tungsten alloy material can be used in this high temperature environment. This prominent feature of tungsten alloys has been used in the aerospace industry.
