Product Description

Corrosion Resistant High Hardness 90WNiFe Tungsten Alloy Drilling Bit 

Tungsten Alloy Drilling Bit is 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 nickel iron, w nickel copper or even w nickel copper iron complexes. Rare earths are added to some tungsten alloys and / or 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.

What is Tungsten Alloy Drilling Bit?

  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 various fields of the national defense industry and the national economy. It is a very important new military material in the national defense industry and is gradually developing to various civil industries.

  2. The heavy tungsten alloy contains 90-98% tungsten and has a high density (16.5-19.00 g / CC). Nickel, iron, and / or copper are used as metal binder substrates to bond fragile tungsten particles together, making tungsten alloys tough and easy to use. Iron nickel is the most commonly used additive, and its ratio is 7Ni: 3Fe or 8ni: 2Fe (calculated by weight).

Application of Tungsten Alloy Drilling Bit

  • It is used as a shielding element for a dual source distance densitometer. The instrument is used to measure the oil content of layers several kilometers below the surface. After transforming the original lead shield element into high specific gravity tungsten alloy, it has been widely used with small volume, high precision and long service life.
