Atomized spherical magnesium powder and related alloy powders have been widely applied in defense, welding materials, polyolefin catalysts, reducing agents, Grignard reagents, magnesium-based hydrogen storage alloys, 3D printing and other fields

Atomized spherical magnesium powder

Atomized spherical magnesium powder is a high-performance metal powder industrially produced by our company for the first time in China with its own patented technology. It has been widely used in defense, polyolefin catalyst, high-end welding materials, high-purity metal reducing agent, Grignard reagent, 3D printing, Mg-based hydrogen storage alloy and other fields. It has solved the problems of low purity, poor fluidity, small bulk density, high moisture absorption rate, poor stability and reproducibility of the traditional mechanical magnesium powder. After years of development, the atomized spherical magnesium powder is becoming more and more perfect and has been sold well in China and more than 20 other countries overseas.

Atomized spherical Mg-Al alloy powder

Compared with the Mg-Al alloy powder produced by the traditional ball milling method, the Mg-Al alloy powder produced by the atomized method of our company has been characterized by high purity (high active Mg+Al content), high activity, high bulk density, high fluidity, high stability , Fine particle size, fine grain size, and small specific surface area etc.; It has been widely used at present, on the basis of ensuring domestic demand, the products are exported to Europe, America, Southeast Asia and other regions, and has been unanimously recognized and praised by users at home and abroad.

Atomized spherical magnesium alloy powder

To meet the current market demand and adapt to the development of science and technology,by using our own patented technology and protecting under the inert gas, we produced a new product-atomized spherical magnesium alloy powder which is characterized by low oxygen, low nitrogen and spherical powder. It includes AZ91D, ZK61, ZK60, AZ31, WE43 and other brands, we can also customize various types of magnesium alloy powder according to the customer’s requirements.

Atomized spherical Mg-Zn alloy powder

The atomized spherical Mg-Zn alloy powder jointly developed with domestic scientific research institutions and produced by Tangshan Weihao has a multi proportion between magnesium & zinc, and a PSD range of 30-500mesh(30μm-500μm). You can choose the different PSD according to your demand and requirement. The atomized Mg-Zn alloy powder has changed the melting point of zinc powder and the starting point of vigorous oxidation, completely solved its ignition and stable combustion problems, and is expected to be widely used in pyrotechnics and other fields.

Atomized spherical Al-based alloy powder

A variety of spherical Al-based alloy powders were prepared by atomized technology in our company, these alloy powders have the following advantages: good sphericity, less bonding, high bulk density, low oxygen content (<600ppm), higher latent heat, combustion heat, theoretical density and oxygen balance. They can be widely used in 3D printing, powder metallurgy, marine engineering, rail transit anticorrosive materials and high-energy explosives.

The production method and device of high-purity atomized spherical magnesium alloy powder were awarded the patent for invention

Through the unremitting efforts of the R&D team of Tangshan Weihao Magnesium Powder Co., Ltd., on the basis of its own patent for invention of atomized magnesium powder, another major technological breakthrough has been achieved, in which a new product of nanocrystalline high-purity atomized spherical magnesium alloy powder was developed. The particle size range of the product was further improved. The size of nanocrystals mainly ranges from 100 to 3000nm, with concentrated distribution, active metal content greater than 98.5%, and the sphericity greater than 95%. The room temperature mechanical properties of the components prepared by high pressure forming and spark plasma sintering through AZ91 magnesium alloy powder in the series products (pressing temperature 250℃, sintering temperature 300℃) are as follows: Tensile strength 420MPa, yield strength 390Mpa, grain size of the components 100-300nm. The mechanical properties of the components prepared by the warm pressing sintering method through ZK61 magnesium alloy powder (temperature 300℃ and pressure load 1000KN) are as follows: Tensile strength 410 Mpa, yield strength 380 MPa, elongation rate 9.5%, and the grain size of the component ranging from 100 to 300nm. The mechanical properties of the components are better than that of ordinary atomized powder.
