Applications
Spherical Aluminum alloy 7075 Powder Reference
- Fabrication of high strength aluminum alloys using laser-based powder bed fusion (L-PBF) encounters challenges, including the occurrence of solidification cracks and the loss of volatile elements, such as Zn and Mg. The current work developed a Si-modified Al7075 alloy aiming at introducing eutectic phases to mitigate the solidification cracking during L-PBF. Based on Kou’s model, the addition of Zn and Mg decreased the crack susceptibility from 6504 to 5966 °C, and the addition of 3.74 wt% of Si further decreased the crack susceptibility to 3960 °C. The Al7075 alloy fabricated by L-PBF exhibited a large amount of solidification cracks extending throughout the sample.

Aluminum 7075 Spherical Powder production involves specific raw materials and methods:
Raw Materials:
- Aluminum 7075 Alloy: The base material used, which includes aluminum with approximately 4.4-4.8% zinc, 1.2-1.6% magnesium, and other elements.
Production Methods:
Gas Atomization:
- Process: Molten Aluminum 7075 is sprayed with high-pressure inert gas (like nitrogen or argon) to form fine spherical particles.
- Advantages: Produces high-quality, spherical powders with good flowability and packing density.
Plasma Atomization:
- Process: The aluminum alloy is melted using a plasma torch, and the molten metal is ejected and solidified into spherical particles.
- Advantages: Provides very high-purity powders with excellent flow characteristics.
Rotating Electrode Process (REP):
- Process: A rotating electrode made of Aluminum 7075 is melted using an electric arc, and the molten metal is thrown off by centrifugal force to form spherical particles.
- Advantages: Produces highly spherical powders with uniform size.
These methods ensure the production of high-quality spherical powders suitable for additive manufacturing and other advanced applications.
