Machined Tungsten Heavy Alloy Pipes 18.5g / Cc High Performance

Product Description

High Performance Machined Tungsten Heavy Alloy Pipes

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

What is Tungsten Heavy Alloy Pipes?

• Tungsten alloy has a series of excellent properties, with high specific gravity: general specific gravity 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong absorption capacity: 30-40% higher than the general specific gravity of lead, large thermal conductivity: 5 times of die steel; Low coefficient of thermal expansion: only 1/2-1/3 of steel steel, good electrical conductivity, good weldability and machinability.

• A common method of manufacturing heavy tungsten alloys is to mix the desired amount of tungsten, iron, nickel, or copper powder and then perform cold pressing and liquid phase sintering to near full density. During the liquid phase treatment, the base tungsten alloy melts and causes some tungsten to enter the solution, forming a microstructure through which large tungsten particles (20-60μm) are dispersed in the base alloy.

Application of Tungsten Heavy Alloy Pipes

The shield part of the dual-source distance density meter is made of tungsten alloy, which is used to measure the oil content of the oil layer thousands of meters below the surface. After the original lead shielding is changed to high specific gravity tungsten alloy, it is widely used because of its small size, high precision and long service life.
