High specific gravity tungsten alloy
The high specific gravity tungsten alloy is a typical two-phase alloy with tungsten as the matrix and a small amount of nickel, cobalt, molybdenum and other elements added. It is also known as the "high density alloy". According to the requirements of different product uses and working environment, the tungsten content of high specific gravity tungsten alloy products is usually distributed between 79%W and 97%W, and the density ranges from 15.00g/cm to 18.50g/cm. At the same time, some rare metal elements (Co,Mo,Cr, etc.) can be added to improve part of the product performance, such as: Of Hardness, Ultimate Tensile Strength, Yield Strength, and of Elongation.
High specific gravity tungsten alloy is a kind of alloy with tungsten matrix (W content 85-99%) and Ni, Cu, Co, Mo, Cr and other elements added.
According to the composition and use of alloy is divided into W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag and other main series, its density is as high as 16.5-19.0g /cm3, and is known as the high specific gravity alloy.
It also has a series of excellent characteristics, than major: general proportion of 16.5-18.75g/cm3, high strength: tensile strength of 700-1000mpa, strong ray absorption capacity: its ability is 30-40% higher than lead, large thermal conductivity: 5 times of die steel; Small thermal expansion coefficient: only iron or steel 1/2-1/3, good conductivity; Good weldability and machinability. In view of the above excellent functions of high specific gravity alloy, it is widely used in aerospace, aviation, military, oil drilling, electrical instrumentation, medical and other industries.
