What is spherical alloy powder? How is the spherical alloy powder prepared?

The spherical alloy powder of Stardust Technology is prepared by "RF plasma spheroidization powder making technology", which uses carrier gas to introduce cheap and irregular powder into the plasma, and uses the ultra-high temperature characteristics of the plasma to melt and cool the powder quickly to achieve spheroidization and modification of the powder. The technology has the characteristics of high product sphericity, less internal defects, controllable particle size, rich variety of raw materials, low price, low energy consumption and high yield. It is especially suitable for large-scale production of high-end rare refractory metals and spherical powder materials.

How to select particle size of spherical alloy powder?

In the process of use, due to the different particle size of the powder used in each process, such as the selection laser melting process uses 15-53μm powder, the thermal spraying process uses 15-45μm powder, the electron beam printing uses 45-105μm powder, and the ordinary powder metallurgy uses 0-150μm powder, so we need to physically separate the powder. The graded powder material can be used in aerospace, biomedical, automotive electronics, mechanical manufacturing and other fields.

What kind of spherical alloy powder has good quality?

1: High density, low porosity.

2: high sphericity, uniform particle size, better process efficiency and finished product performance.

3: Low oxygen content, no hollow satellite powder.

4: Good liquidity, suitable for complex products.
