Compared with cast iron weight blocks, tungsten-based alloys have higher overall performance

China has the largest tungsten reserve and tungsten output whose reserve are four times of other countries in the world, tungsten ore was found early 10th century and was called "heavy stones" at that time.

It is reported that China Aerospace Science and Technology Corporation (CASTC) will begin to develop a high-tech aircraft, which is more efficient than the retired space shuttle. It uses a variety of power and can take off from ordinary airports and fly straight into orbit.

Tungsten is a rare metal with a shape similar to steel. Because of its high melting point, high hardness, excellent corrosion resistance, and good electrical and thermal conductivity, it has become one of the most important functional materials in modern industry, national defense etc.

Compared with traditional electrode materials, tungsten-based electrode materials have the characteristics of high melting point, good corrosion resistance, high density, and superior thermal and electrical conductivity, so they are widely used in the field of welding.

In order to avoid environmental pollution caused by military materials, tungsten alloy military products are gradually replacing lead and depleted uranium for bullets and armor-piercing bullets. In the military field, tungsten alloy military products are gradually becoming popular.

China tungsten price was in the upward trend in the week ended on Friday July 31, 2020, but affected by the weakness both in the supply and demand sides, transactions were poor at the end of this month.

Molybdenum crucibles and tungsten crucibles are widely used in rare earth smelting, vacuum sintering, laser crystal growth and other industries. Due to the high price of tungsten and molybdenum and the harsh processing conditions, the repeated use of crucibles has become a concern for manufacturers.

Most tungsten concentrates are processed chemically to ammonium paratungstate (APT). Secondary raw materials like (oxidized) scrap and residues are another important feed for chemical tungsten processing.

Tungsten carbide (WC) has excellent properties of high hardness, high strength, high rigidity, good wear resistance, and thermal conductivity. It has wide application files of tools in the metalworking, drilling, and mining industries under severe conditions of high-pressure
