Machined 90WNiCu High Performance Heavy Tungsten Alloy Molds

Heavy Tungsten Alloy Molds are made of tungsten matrix (tungsten content is generally 80%~98%) and a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements. The density of high specific gravity tungsten alloy is up to 15.20~18.70g/cm3, also known as high specific gravity tungsten alloy or high density alloy material. Because tungsten alloys weigh more than twice as much as steel.

What is Heavy Tungsten Alloy Molds?

Tungsten alloy has a series of excellent properties, high specific gravity: general specific gravity 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong absorption capacity: 30-40% higher than the general specific gravity of lead, high thermal conductivity: 5 times of mold steel; Low thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity, good weldability and machinability.
A common method of making heavy tungsten alloys is to mix tungsten, iron, nickel, or copper powder in the desired amount and then mix it with a cold press and liquid sinter to near full density. During the liquid phase treatment, the base tungsten alloy melts and causes some tungsten to enter the solution, forming a microstructure through which large tungsten particles (20-60μm) are dispersed in the base alloy.

Application of Heavy Tungsten Alloy Molds

Mold is a low-chip, chip-free precision casting process, which can directly produce complex shaped parts. Single process, high yield, no porosity, save raw materials, especially in iron metal die casting, mold working conditions are very bad, must be able to withstand high temperature, high pressure and metal flow erosion, and can resist corrosion, oxidation and thermal impact. High specific gravity tungsten alloy has good thermal conductivity and corrosion resistance, which is a good die casting material. Compared with the copper mold, its service life is increased dozens of times.
