Wearing Resistance Tungsten Alloy Bore Bit,
Petroleum Industry Tungsten Alloy Bore Bit
Tungsten Alloy Bore Bit is heavy tungsten screws because they weigh more than twice 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 is more than 50% heavier than lead.
Heavy tungsten alloys are mainly divided into w nickel iron, w nickel copper and even w nickel iron copper series. In contrast, Western ferronickel alloys have better mechanical properties and play an important role in national defense industry and national economy. It is a very important new military material in the national defense industry and is gradually developing to various civilian industries.
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 bonding substrates to bond fragile tungsten particles together, making tungsten alloys tough and easy to use. Iron and nickel are the most commonly used additives, with the ratio of 7Ni: 3Fe or 8ni: 2Fe (calculated by weight).

It is used as a shielding element for a dual source distance densitometer. The instrument is used to measure the oil content of the strata several kilometers below the surface. Turning the original lead shielding element into a high-specific gravity tungsten alloy has a small size, a high precision and a long service life.
