Spherical W-Mo-Ta-Nb high entropy alloy powder 45-106μm

Spherical W-Mo-Ta-Nb alloy powder is an alloy powder composed of elements such as tungsten (W), molybdenum (Mo), rhenium (Ta) and niobium (Nb). It has excellent high temperature performance and corrosion resistance and is widely used in high-tech fields.

1. Characteristics:

- High melting point and thermal stability: Elements such as tungsten, molybdenum, rhenium and niobium have high melting points (3422°C for tungsten), so W-Mo-Ta-Nb alloy can maintain good mechanical properties and stability in high temperature environments.

- High strength and hardness: The alloy powder has high tensile strength, hardness and compressive strength, and is particularly suitable for applications working under high loads and high temperatures.

- Corrosion resistance: Elements such as molybdenum, rhenium and niobium in the alloy enhance its tolerance to corrosive media such as acids and alkalis at high temperatures, and have excellent chemical stability.

- Good thermal conductivity and electrical conductivity: Due to the high thermal conductivity and electrical conductivity of tungsten, W-Mo-Ta-Nb alloy performs well in environments that require heat dissipation and electrical conductivity.

2. Application areas:

- High temperature alloy materials: widely used in aerospace, nuclear energy, petrochemical and other fields, especially high temperature components such as jet engines, rocket propulsion systems, etc.

- Electronic components: used to manufacture high temperature electronic components, vacuum electronic equipment and high power electrical appliances, especially those requiring good thermal stability.

- Radiation protection materials: Due to the high density and good shielding properties of tungsten, the alloy can be used for radiation protection, such as in medical equipment and nuclear facilities.

- Arc and high temperature electrodes: The electrical conductivity of the alloy at extremely high temperatures makes it suitable for arc furnaces, electrodes and other electrical equipment in high temperature environments.
