Nature of Kekai Tungsten & Molybdenum technology molybdenium and tungsten is very close to the boiling point and highlight its conductive properties , linear thermal expansion coefficient
The number is small, compared with the tungsten easier processing.
Thermal conductivity metal screen with the best match to the specific heat , making thermal shock and thermal fatigue
Natural selection , after which the melting point of tungsten , but the density is smaller and therefore the strength of
Greater than tungsten and other metals in the application of the weight of several key requirements , the more effective. molybdenum alloys in order
Before two hundred people have high degrees of strength.
The main drawback is the mother of poor oxidation resistance above six hundred degrees Celsius rapid oxidation
And poor ductility at room temperature . To avoid weaknesses, using high-temperature oxidation coating ways to control the problem ,
For that is the lack of generally low temperature embrittlement said too poor plasticity , the strengthening Canadian people by alloy
Carbides and other measures to strengthen the resolve to achieve .
Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.
