90%WNiFe Tungsten Heavy Alloy Bolts High Temperature Resistance

Product Description

90%WNiFe High-Temperature Resistance Tungsten Heavy Alloy Bolts

Tungsten Heavy Alloy Bolts are made of tungsten base (tungsten content is generally 80%~98%) and a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements. The density of gravity tungsten alloy is as high as 15.20~18.70g/cm3, also known as gravity tungsten alloy or high-density alloy material. Because tungsten alloy weighs more than twice as much as steel.

Introduction and Feature of Tungsten Heavy Alloy Bolts

1. Tungsten alloy has a series of excellent properties, high specific gravity: general gravity lead 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong light absorption capacity: 30-40% higher than general gravity lead, and thermal conductivity: 5 times of modulus steel; Low thermal expansion coefficient: only 1 / 2-1 / 3 of carbon steel, good conductivity and good welding processing skills.

2. A common method of making heavy tungsten alloys is to mix the desired amount of tungsten, iron, nickel or copper powder, then cold-press and liquid-phase sinter to near full density. During the liquid phase treatment, the matrix tungsten alloy is melted, and part of the tungsten enters the solution to form a microstructure, so that larger tungsten particles (20-60m) are dispersed in the matrix alloy.

Application of Tungsten Heavy Alloy Bolts

• The dual source range densitometer uses tungsten alloy as the shielding element to measure the oil content of the oil layer several kilometers below the surface. This instrument has been widely used for its small size, high accuracy and long service life.
