The cumulative import volume of molybdenum products in China from January to March 2023 was 11442.26 tons, a year-on-year increase of 96.98%; The cumulative import amount was 1.807 billion yuan, an increase of 168.44% year-on-year.
Cemented carbide and high-speed steel are typical downstream products of refractory metal tungsten (W), both have good thermodynamic properties, and can be used to make cutting tools, cold-working molds and hot-working molds, etc.
Tungsten Alloy is an alloy material made by powder metallurgy process or injection molding technology with refractory metal tungsten as the hard phase and nickel, iron, copper, cobalt or molybdenum as the bonding phase. It has excellent thermal, mechanical, chemical and electrical properties
The reason why cemented carbide (cemented carbide) can be widely used in aerospace, aviation, navigation, consumer electronics, national defense, military, medical, automotive and other fields is that it has extremely excellent physical and chemical properties
About 85% to 90% of the world's niobium is used in iron and steel production in the form of ferroniobium. Only adding 0.03% to 0.05% of niobium to the steel can increase the yield strength of the steel by more than 30%.
Among the metal materials used for human hard tissue repair, the elastic modulus of titanium is the closest to human tissue, which can reduce the impact of metal implants and bone Mechanical incompatibility between tissues.
Molybdenum (Mo) and molybdenum alloy materials have been widely used in various industrial fields such as manufacturing industry, aerospace industry, steel smelting, petrochemical industry, medical equipment, national defense construction, etc. Mammography.
In order to make up for the poor high temperature strength and low oxidation resistance of pure molybdenum alloy, producers often dope appropriate amount of additives such as zirconium hydride, yttrium oxide and cerium oxide in their production process
According to customs data, from January to May 2022, China's total import volume of molybdenum products was 12,806.91 tons, a year-on-year decrease of 62.59%; the cumulative import value was 1,503.6212 million yuan, a year-on-year decrease of 38.62%.
In 1792, the Swedish chemist Elm used a mixture of charcoal and molybdic acid blended with linseed oil and burned in a sealed manner to obtain molybdenum. Because metallic molybdenum has the advantages of high strength, high melting point, corrosion resistance, and wear resistance
