Best Tungsten Bullet Weights is a kind of tungsten alloy, which weighs more than twice as much as steel. The high specific gravity tungsten alloy is usually a refractory metal containing W-Ni-Fe, W-Ni-Cu or even W-Ni-Cu-Fe two-phase complex. Rare earths and/or other metals such as cobalt, molybdenum and chromium are added to some tungsten alloys. Tungsten alloys have a high melting point, are twice as dense as steel and more than 50 percent heavier than lead.

The Best Tungsten Bullet Weights are mainly divided into W-Ni-Fe
series, W-Ni-Cu series and even W-Ni-Fe-Cu series. In contrast,
W-Ni-Fe alloy has better mechanical properties and plays a great
role in various fields of defense industry and national economy. It
is a very important new military material in the national defense
industry, and gradually extended to a variety of civilian
industries.
Heavy tungsten alloys contain 90-98% tungsten, which is responsible
for their high density (16.5-19.00 g/cc). Nickel, iron and/or
copper are used as metal adhesives to hold fragile tungsten
particles together, making tungsten alloys strong and easy to use.
Nickel is the most commonly used additive, in ratios of 7Ni:3Fe or
8Ni:2Fe by weight.
Best Tungsten Bullet Weights tackle pendant is a kind of tungsten
alloy material made of fishing tackle. Tungsten alloy fishing
pendant has high density, small volume and various shapes, which is
suitable for various river sections. Tungsten alloy hangers offer
advantages over other manufacturing materials.
