High Specific Gravity Heavy Tungsten Alloy Rings Strong Light Absorption

Product Description

High Performance Machined Heavy Tungsten Alloy Rings

Heavy tungsten alloy rings 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 Heavy Tungsten Alloy Rings

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, thermal conductivity: 5 times that of modulus steel; low thermal expansion coefficient: only 1/2-1/3 of carbon steel, good electrical conductivity, good welding and processing skills.

    

2. A common process for making heavy tungsten alloys involves mixing the desired amount of tungsten, iron, nickel or copper powder, followed by cold pressing and liquid phase sintering to near full density. During the liquid phase treatment, the matrix tungsten alloy melts and some tungsten enters the solution to form a microstructure, so that larger tungsten particles (20-60m) are dispersed in the matrix alloy.

Application of Heavy Tungsten Alloy Rings

• The dual source range density meter uses a tungsten alloy as the shielding element to measure the oil content of the oil layer several kilometers below the surface. The instrument is widely used because of its small size, high precision and long service life.
