Products made of tungsten-containing alloys
The main applications of products made of tungsten-containing alloys are determined by their basic properties. Due to the fact that tungsten alloys exhibit high levels of radiation protection due to their high density (tungsten alloys are at least 1.5 times heavier than lead), they are therefore deservedly considered the best material for protection against gamma rays in comparison with traditionally used lead, and also steel, water and cast iron. In addition, tungsten has a unique set of qualities and properties that allows it to be used in working with extremely high temperatures. Therefore, products from tungsten-containing alloys are widely used in many industries.
Properties:
- High density tungsten alloy;;
- High rates of radiation protection;
- High wear resistance;
- Heat resistance ;
- Lowest corrosion rate;
- Relatively reasonable price.
Application area:
- Details of radioactive logging tools;
- Storage tanks for radioactive substances;
- Protective screens;
- Collimators;
- Elements of non-destructive testing equipment;
- Dosimetric equipment and radiation monitoring equipment, etc.
The following alloys are most popular: tungsten-nickel-iron, tungsten-copper, tungsten carbide. Copper, nickel and iron in combination with tungsten increase the ductility of the material and its electrical conductivity, improve its workability.
