Product Use
Graphite crucible for melting copper, aluminum, gold, silver, lead, zinc and other nonferrous metals and alloys.
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.
