High Performance 90WNiCu Machined Tungsten Heavy Alloy StudTungsten Heavy Alloy Stud is a kind of tungsten as a matrix alloy
material (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
can reach 15.20~18.70g/cm3, also known as high specific gravity
tungsten alloy or high density alloy material. Because tungsten
alloy weighs more than twice as much as steel. SPECIFICATIONS & CHEMICAL COMPOSITIONS (NOMINAL)| Chemical Composition | 90%W | 93%W | 95%W | 97%W | | State | Sinter | Vacuum | Forge | Sinter | Vacuum | Forge | Sinter | Vacuum | Sinter | Vacuum | Density

Tungsten Heavy Alloy Stud Picture:What is Tungsten Heavy Alloy Stud?- Heavy tungsten alloys are mainly divided into nickel nickel iron,
nickel nickel alloy, nickel copper and even tungsten alloy. In
contrast, o-ni-fe alloy has good mechanical properties and plays an
important role in national defense industry and national economy.
It is a very important new military material in the national
defense industry, and has been gradually extended to various
civilian industries.
- The tungsten content of tungsten alloys varies from 90% to 98%,
which is the reason for their high density (16.5 to 19.00g/CC).
Nickel, iron, and/or copper are used as metal binder bases to hold
the fragile tungsten particles together, making the tungsten alloy
malleable and easy to work with. Ferronicel is the most commonly
used additive in 7Ni: 3Fi or 8Ni: 2Fe
Application of Tungsten Heavy Alloy StudHeavy tungsten alloys are used to make knife holders, especially
for boring rods. The high crankshaft of the forest chainsaw small engine uses the
high density tungsten alloy as the counterweight material. EDM and electrochemical machine tool electrodes are also made of
tungsten-gold with high gravity
