Product Description
Heavy Tungsten Alloy Mould is heavy tungsten screws because they weigh more than twice as much as steel. Tungsten alloys with high specific gravity are usually refractory metals containing w-ni-fe-f, W-Ni-Cu or even w-ni-cu-fe-f complexes. Rare earth metals are added to some tungsten alloys with other metals, such as cobalt, molybdenum and chromium. Heavy tungsten alloy has a high melting point, twice the density of steel and more than 50% heavier than lead.

Heavy tungsten alloys are mainly divided into w nickel iron, w nickel copper, and even w nickel iron copper series. In contrast, ferronickel alloys in the West have better mechanical properties and play an important role in various fields of national defense industry and national economy. It is a very important new military material in the national defense industry, and is gradually developing into various civil industries.
The heavy tungsten alloy contains 90-98% high-density tungsten (16.5-19.00g/cc). Nickel, iron, and / or copper are used as metal binders to bond brittle tungsten particles together, making tungsten alloys tough and easy to use. Fe Ni is the most commonly used additive, and its mass ratio is 7ni:3fe or 8ni:2fe.
Die casting is a low chip, chip free precision casting process, which can directly manufacture parts with complex shapes. The process is simple, the yield is high, there is no hole, and the raw materials are saved. Especially in the process of metal iron die casting, the working conditions of the die are very poor, so it must be resistant to high temperature, high pressure and metal flow corrosion, and can withstand corrosion, oxidation and thermal shock. Tungsten alloy with high specific gravity has good thermal conductivity and corrosion resistance. It is an excellent die-casting material. Compared with copper mold, its service life is increased by dozens of times.
