What Types of High-Density Alloys are There?

High-density alloy is a type of alloy with tungsten as the matrix (content 85-99%) and added elements such as Ni, Cu, Co, Mo, and Cr. According to alloy composition characteristics and uses, high-density alloys are mainly divided into the following categories:

  1. W-Ni-Fe series: An alloy composed of W as the main element and adding Ni and Fe elements. This alloy has high strength, high hardness, good corrosion resistance and oxidation resistance, as well as good electrical and thermal conductivity. It is widely used in aerospace, defense industry and civil industry.
  2. W-Ni-Cu series: An alloy composed of W as the main element and adding Ni and Cu elements. This alloy has high strength, high hardness, good corrosion resistance and oxidation resistance, as well as good electrical and thermal conductivity. It is widely used in the fields of electronic industry, communication equipment and power equipment.
  3. W-Co series: An alloy composed of W as the main element and the addition of Co element. This alloy has high strength, high hardness, good corrosion resistance and oxidation resistance, as well as good electrical and thermal conductivity. It is widely used in aerospace, defense industry and civil industry.
  4. W-WC-Cu series: An alloy composed of W and WC as the main elements and adding Cu element. This alloy has high strength, high hardness, good corrosion resistance and oxidation resistance, as well as good electrical and thermal conductivity. It is widely used in aerospace, defense industry and civil industry.
  5. W-Ag series: An alloy composed of W as the main element and the addition of Ag element. This alloy has high strength, high hardness, good corrosion resistance and oxidation resistance, as well as good electrical and thermal conductivity. It is widely used in the fields of electronic industry, communication equipment and power equipment.

The above are the main types of high-density alloys. They all have the advantages of high density (above 10.0g/cm³), high strength, high hardness, good corrosion resistance and oxidation resistance. They are widely used in aerospace, defense industry, civil industry and It is widely used in other fields.
