The material of tungsten alloy with high specific gravity, what kind of material is tungsten alloy

High-specific gravity tungsten alloy is an alloy material composed of tungsten as the matrix material (of which the tungsten content is 85% and 99%) and a small amount of nickel (Ni), copper (Cu), iron (Fe), cobalt (Co), molybdenum (Mo), chromium (Cr) and other metal binders, also known as high-density tungsten alloy or heavy alloy [1]. The density of tungsten alloys with high specific gravity can be reached. The most commonly used ones are:

W-NI-CU and W-NI-FE series. This material has significant characteristics in physical properties such as density, strength, hardness, ductility, electrical and thermal conductivity, etc., so it has been widely used in the national defense industry, aerospace industry, medical industry, electrical industry and other industries.

The materials of tungsten alloy with high specific gravity can be divided into tungsten nickel iron alloy, tungsten nickel copper alloy and tungsten molybdenum nickel iron alloy.

The main grades of tungsten nickel-iron alloy are: W90NiFe, W93NiFe, W95NiFe

Tungsten nickel-iron alloy is an alloy composed of a small amount of nickel, iron and other alloying elements added to tungsten as the matrix, which has the characteristics of high density (and adjustable, strong ability to absorb high-energy rays (1 3 higher than the ray absorption coefficient of lead), low thermal expansion coefficient (4 6 10-6), good plasticity, high strength and elastic modulus, machinability, and weldability. It is widely used in radiation protection and guidance (hyperlink), industrial counterweight parts (hyperlink), safety and defense parts (hyperlink), etc.

It is mainly used in the radiation protection and guidance industry, industrial counterweight parts, safety and defense parts, nuclear power and energy parts.

The main grades of tungsten-nickel-copper alloy are: W90NICU, WU93NICU, and WU95NICU

Tungsten-nickel-copper alloy is an alloy composed of a small amount of nickel, copper and other alloying elements added to tungsten as the matrix, which has the characteristics of non-magnetic, high density (and adjustable, strong ability to absorb high-energy rays (1 3 higher than the ray absorption coefficient of lead), low thermal expansion coefficient (4 6 10-6), machinability, and weldability. It is widely used in the field of radiation shielding and protection that is sensitive to the magnetic environment.

The main grades of tungsten-molybdenum-nickel-iron alloy are: 90wmonife

Tungsten-molybdenum-nickel-iron alloy is an alloy composed of a small amount of nickel, iron, molybdenum and other alloying elements added to tungsten as the matrix, which is produced by powder metallurgy.

Refractory metal materials

The alloy formed by adding other elements based on tungsten is an important class of refractory metal materials. In 1913, thorium-tungsten alloy was developed.

In 1922, anti-sagging tungsten wire was invented, high-density tungsten alloy was developed in 1935, and tungsten-rhenium alloy was developed in the 50s of the 20th century. Tungsten alloy material is widely used in electronics, electric light source, aerospace, military industry, machinery and metallurgy.

Summary. The State Key Laboratory of New Metal Materials of University of Science and Technology Beijing has successfully experimented, and a new generation of aerospace engine materials with China's independent intellectual property rights——— high-temperature and high-niobium titanium aluminum alloy materials are about to enter the industrialization stage, and this technology will make China's aerospace engine materials rank at the world's leading level. After 20 years of research work, the research team of the State Key Laboratory of New Metal Materials of Beijing University of Science and Technology, led by Academician Chen Guoliang, has developed a high-temperature, high-performance high-niobium titanium-aluminum alloy, which has a higher operating temperature than the general niobium-titanium-aluminum alloy used in advanced countries and is generally accepted internationally.

High-temperature and high-niobium titanium aluminum alloy can replace high-performance deformed nickel-based superalloy, and the density is about half that of nickel-based superalloy, so that the component has a significant weight reduction effect.

Hello dear, the effect of high-performance niobium-aluminum alloy ingredient ratio on the alloy is that the adhesion of aluminum alloy to the mold is very strong, and when the iron content is particularly strong below, that is, there is a phenomenon that is not easy to release the mold. In China's new generation of aviation, it is believed that Somao has used high-temperature niobium-titanium aluminum alloy materials with independent intellectual property rights, and the world has broken a new path for improving the performance of the engine.
