Product Description

Corrosion Resistance 90WNiFe Heavy Tungsten Alloy Dies 

Heavy Tungsten Alloy Dies are heavy-duty tungsten screws because they weigh more than twice as much as steel. High specific gravity tungsten alloys are usually refractory metals containing W ni-fe, W Ni-cu or even W Ni-cu-Fe complexes. Rare earths add/or other metals such as cobalt, molybdenum, and chromium to some tungsten alloys. Heavy tungsten alloys have a high melting point, are twice as dense as steel and more than 50 percent heavier than lead.

What is Heavy Tungsten Alloy Dies?

  1. Heavy tungsten alloys are mainly divided into W nickel-iron, W nickel-copper, and even W nickel-iron-copper series. In contrast, western nickel-iron alloys have better mechanical properties and play an important role in the defense industry and various fields of the national economy. It is a very important new military material in the national defense industry, and is gradually developing into a variety of civilian industries.

  2. Heavy duty tungsten alloys contain 90-98% high density tungsten (16.5-19.00g/CC). Nickel, iron, and/or copper are used as metal binder bases to hold brittle tungsten particles together, making the tungsten alloy tough and easy to use. Fe-ni is the most commonly used additive, with a weight ratio of 7Ni: 3Fe or 8Ni: 2Fe.

 

Application of Heavy Tungsten Alloy Dies

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