High Density Tungsten Heavy Alloy (WNIFE) Part
Description
We are supplier specialized in manufacturing tungsten heavy alloy parts. We use raw material of tungsten heavy alloy with high purity to produce their parts. High temperature re-crystallization is one of the important features for tungsten heavy alloy parts. Moreover, it has high plasticity and excellent abrasive resistance. Its re-crystallization temperature is over 1500℃. The tungsten heavy alloy parts conform to ASTM B777 standard.
Properties
The density of tungsten heavy alloy parts is 16.7g/cm3 to 18.8g/cm3. In addition, tungsten heavy alloy parts have characteristics of high temperature and corrosion resistance. Tungsten heavy alloy parts have good shock resistance and mechanical plasticity. Tungsten heavy alloy parts have low thermal expansion coefficient, ability of absorbing high energy rays.

Customized Tungsten Molybdenum Alloys Rods
Description An alloy composed of tungsten and molybdenum. Commonly used tungsten-molybdenum alloys contain 30% to 50% tungsten (by mass). Tungsten molybdenum alloys are produced in the same way as molybdenum metal and molybdenum alloys, i.e., both powder metallurgy post-sintering processing and smelting processing to produce rods, plates, wires or other profiles. Tungsten molybdenum alloys containing 30% tungsten (by mass) have excellent corro...

Polished Molybdenum Disc& Molybdenum Square
Description Molybdenum is gray-metallic and has the third-highest melting point of any element next to tungsten and tantalum. It is found in various oxidation states in minerals but does not exist naturally as a free metal. Molybdenum allows readily to form hard and stable carbides. For this reason, Molybdenum is frequently used for making steel alloys, high strength alloys, and superalloys. Molybdenum compounds usually have a low solubility i...
