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
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.
Among all refractory metals, molybdenum is the most commonly used metal. When made into an alloy, it has extremely high resistance to high temperatures and creep, making it extremely resistant to corrosion.
Tungsten alloy swaging rods are tungsten alloy products manufactured by forging tungsten alloy rods. After a series of thermomechanical treatments, this kind of bar can greatly improve its mechanical properties and is widely used in military, transportation, medical and other fields.
Tungsten alloy, also known as high specific gravity tungsten alloy, is considered by everyone to be the best material for marine counterweights due to its advantages of higher density, greater tensile strength, and better corrosion resistance.
Cemented carbide is the most widely used type of high-speed machining (HSM) tool material. This type of material is produced by powder metallurgy, and consists of hard carbide (usually tungsten carbide WC) particles and a softer metal bond composition.
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.
Cemented carbide indexable CNC tools are tools used for cutting in mechanical manufacturing, also called cutting tools. In a broad sense, cutting tools include both cutting tools and abrasive tools
Molybdenum-copper alloy is actually a pseudo-alloy composed of two non-solid-soluble metals, but it has both the characteristics of molybdenum and copper and has good comprehensive properties.
Tungsten alloy crankshaft is an important part of the engine that bears impact load and transmits power. Among the five major parts of the engine, the crankshaft is the most difficult to ensure the processing quality.
