WNiCu High Performance Machined Tungsten Heavy Alloy Tubes PipeTungsten Heavy Alloy Tubes Pipe 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 are added. The density of high specific gravity tungsten
alloy is as high as 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 iron or steel. SPECIFICATIONS & CHEMICAL COMPOSITIONS (NOMINALS)| Chemical Composition | 90%W | 93%W | 95%W | 97%W | | State | Sinter | Vacuum | Forge | Sinter | Vacuum | Forge | Sinter | Vacuum | Sinter | Vacuum | Density

Tungsten Heavy Alloy Tubes Pipe Picture:
Introduction and Feature of Tungsten Heavy Alloy Tubes
Pipe- Tungsten alloy has a series of excellent properties, high specific
gravity: general specific gravity 16.5-18.75g/cm3, high strength:
tensile strength 700-1000mpa, strong ray absorption capacity: its
capacity is 30-40% higher than the ordinary specific gravity of
lead, thermal conductivity Large: 5 times that of die steel; small
thermal expansion coefficient: only 1/2-1/3 of steel, good
electrical conductivity; good weldability and machinability.
- A common process for preparing tungsten heavy alloys involves
mixing the desired amount of tungsten, iron, nickel or copper
powder, followed by cold pressing and liquid phase sintering to
nearly full density. During the liquid phase treatment, the base
tungsten alloy melts and brings some tungsten into the solution,
forming a microstructure through which large tungsten particles
(20-60 μm) are dispersed in the base alloy.
Application of Tungsten Heavy Alloy Tubes PipeTungsten alloy is used as the shield part of the double source
distance density measuring instrument, which is used to measure the
oil content of the oil layer thousands of meters below the surface.
After the original lead-made shield part is changed into high
specific gravity tungsten alloy, the instrument has been widely
used with small volume, high accuracy and long service life. |
