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.
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.
