With its advanced and innovative production technology, CNPC Powder has officially become the first domestic powder manufacturer to obtain official authorization from APWORKS for the production and sale of high-strength aluminum alloy Scalmalloy® 3D printing materials.

Scalmalloy® is a high-performance aluminum alloy powder material composed of select elements such as aluminum, magnesium, and scandium, specifically designed for additive manufacturing. It features a bimodal microstructure where fine equiaxed grains are separated by larger columnar grains, with the addition of Sc and Mg at a hypereutectic point (eutectic content of 0.4-0.55 wt%) to refine the grains and enhance strength.

Compared to traditional aluminum alloys, Scalmalloy® exhibits exceptional properties. It has a tensile strength of up to 533 MPa and a yield strength of up to 527 MPa, while maintaining good ductility under high stress, with an elongation at break exceeding 10%, which is superior to traditional 7-series aluminum alloys. Scalmalloy® also has a lower density, being approximately 60% lighter than titanium alloys of the same volume, significantly reducing structural weight and making it suitable for applications where weight reduction is required.

CNPC Powder adopts an innovative AMP process for powder production, which upgrades the traditional single-batch production mode to continuous, uninterrupted production. The resulting powder exhibits excellent sphericity and flowability, with a sphericity exceeding 90% and a uniform particle size distribution between 20-63μm, ensuring high precision and superior surface quality of the printed parts. Notably, the powder has an extremely high purity, with an oxygen content as low as approximately 300ppm and minimal impurity levels. We strictly control the ratio of hollow and satellite particles and adhere to rigorous production standards, carefully monitoring each batch of powder materials to effectively accelerate the widespread application and popularization of Scalmalloy® in the metal 3D printing industry.

Applications: High-end manufacturing fields with high strength requirements, such as aerospace, automotive, consumer electronics, medical, low-altitude economy, artificial intelligence, and more.
