Magnesium  Alloy Extruded Bars

Specific features

In addition to the common characteristics of magnesium alloys, extruded magnesium alloy bars have the following specific features.

Excellent Grain Structure: The extrusion process significantly refines the alloy's grain structure, enhancing material strength, toughness, and fatigue resistance.

Material Efficiency: The extrusion process typically offers high material utilization, reducing waste generation and lowering production costs.

Energy Efficiency and Environmental Friendliness: Compared to other manufacturing methods, extrusion processes often save energy and reduce emissions, contributing to better environmental performance.

Secondary forming applications 

Re-Extrusion and Rolling: Extruded magnesium alloy rods can undergo further cold or hot extrusion to achieve more complex shapes, such as pipes and profiles. These forming processes can further refine the material's grain structure, enhancing strength and toughness.

Processing into Parts and Components: Through cutting, stamping, drilling, and other processing techniques, extruded magnesium alloy rods can be transformed into various parts and components, such as automotive parts, aerospace components, and industrial equipment parts.

Welding and Joining: Extruded magnesium alloy rods can be welded, riveted, and joined to create larger structures, such as vehicle frames and aircraft structures.

Assembly and Integration: Extruded magnesium alloy rods can be used to manufacture components that are later assembled into complete devices, such as mechanical systems and electronic equipment.
