ASTM High Strength Magnesium Alloy Az31 Bar For Civil Industry

Fast Heat Dissipation High Strength Magnesium Alloy Bar For Civil Industry

Introduction:

High Strength Magnesium alloy bar has small, high specific strength, good electrical and thermal conductivity, corrosion resistance, beautiful shape, easy processing into density shape and other excellent performance, is widely used in aviation, aerospace, automotive, construction, electrical, chemical, machinery manufacturing and other industries. High strength magnesium alloy bar is an important structural material indispensable for many military and civil aircraft and transportation tools.

Extrusion process:

Magnesium alloy tubes, bars, profiles and strips can be produced by extrusion. For the forming of low plastic materials, extrusion is an ideal processing method. Most wrought magnesium alloys such as AZ31B, AZ61, ZMZI, ZK60, HK31 alloys can be produced by extrusion.

Features:

Due to the good thermal conductivity and low cutting force of magnesium alloys, the heat dissipation rate during processing is very fast, so the tool life is long and the amount of sticking to the tool is small, which can reduce tool costs and shorten the downtime required for tool replacement.

Because magnesium is easy to cut, its chip breaking performance is very good, and generally only one finishing operation is needed to achieve the required final surface finish.

Processing performance advantage:

1. The melting cost is only 2/3 of that of aluminum:

2. Excellent die-casting formability: magnesium alloys can be die-casted to manufacture complex parts and ultra-thin shell parts, the thinnest can reach 0.45mm (ABS plastic is 1.2-2mm, aluminum alloy is 1.5-2mm), and the surface quality of magnesium castings and the The appearance is obviously better than that of aluminum: the affinity of magnesium die-casting with the mold is much lower than that of aluminum, and the life of the mold is more than twice that of aluminum.

3. The production efficiency of die casting is 25% higher than that of aluminum, metal mold casting is 300-500K higher than aluminum, and lost foam casting is 200% higher than aluminum.

4. Good cutting performance: magnesium alloy has low hardness and good cutting performance. The cutting resistance is only 56% of aluminum alloy and 43% of brass. High cutting speed and cheap cutting can be used for processing. Cutting tools, low tool consumption. And without grinding and polishing, you can get a very smooth surface with cutting fluid.

Application:

The automotive industry and the electronics industry have become the industries with the largest demand for magnesium alloys. The use of magnesium alloys in automobiles can reduce the weight by 20% to 25% compared with aluminum alloys. Magnesium alloy extrusions can be used in automotive bearing parts such as seat frames, window frames, chassis frames, wheel hubs, etc. Thin-wall magnesium alloy extruded pipe fittings are used in automobiles, and due to their small cross-sectional area, they can significantly reduce weight. Magnesium alloy sheets are used in the manufacture of outer panels for automotive body parts (such as doors, covers, guards, roof panels, etc.), which can greatly reduce the mass.
