AZ40M alloy is a magnesium-aluminum-zinc-based wrought magnesium alloy that cannot be strengthened by heat treatment. The alloy exhibits poor formability at room temperature but demonstrates good plasticity at elevated temperatures, making it essential to perform all forming processes while the material is heated.
The product features a smooth, glossy, and flawless surface, free from burrs, dents, creases, or any other oxidation-related impurities. X-ray inspection reveals minimal gas and slag content in the welds, along with a narrow heat-affected zone, resulting in significantly enhanced strength. This ensures the product meets the stringent quality standards required for military applications, while also dramatically improving the overall welding yield.
Zhonglu Light Alloy Research utilizes high-purity metals as raw materials and employs a vacuum melting-casting-extrusion-drawing process to produce aluminum-magnesium-scandium alloy wires. By leveraging vacuum melting technology, the process effectively addresses common challenges in high-magnesium aluminum alloy casting—such as hydrogen absorption, oxide slag formation, compositional segregation, and severe shrinkage porosity—enabling the creation of highly purified, high-quality extruded billets made from aluminum-magnesium-scandium alloys. This ensures a robust foundation for subsequently manufacturing premium-quality aluminum-magnesium-scandium alloy welding wires.
