In a dust-free workshop in Fengyang Economic Development Zone, Anhui Province, micron-sized silver powder is pouring out of the atomization equipment. These seemingly ordinary metal powders carry the hope of the 3D printing industry to overcome the safety pain points - they are magnesium alloys, but they will not burn easily.

On June 26, 2025, according to the resource library, 3D printing metal powder manufacturer Zhongti New Materials announced that the first industrial mass-produced 3D printing flame-retardant magnesium alloy powder CNPC-AZX912 was officially launched. This innovative material with a ignition point of up to 620°C is expected to reduce the flammable and explosive safety risks of magnesium alloys in 3D printing applications.

Magnesium alloy is currently the lightest metal structural material with a density of only 2/3 of that of aluminum alloy. It has higher specific strength and good shock absorption performance. It is known as the "21st century green engineering material" and is widely used in aerospace, automotive, medical and other fields. However, due to its high chemical activity, magnesium alloys are easy to burn or even explode in 3D printing, which has become a key problem restricting its industrial application.

Zhongti New Materials told the resource library that the company not only retained the advantages of magnesium alloy in terms of lightweight and high specific strength through the optimization of material composition and surface technology, but also greatly reduced the risk of dust explosion, and the material is safer and more controllable during storage, transportation and printing.
