ASTM High Strength Magnesium Alloy Bar 2mm Silicon Alloy For Communication Parts

Easy To Recycle High Strength Magnesium Alloy Bar For Communication Equipment Structural Parts

Introduction:

The crystal structure of magnesium and the electronic structure of the outer layer of the nucleus determine the special physical and chemical properties and mechanical properties of magnesium and its alloys. Due to the low strength of pure magnesium, it is rarely used as a structural material in industry. Like other non-ferrous materials, materials scientists have been working on the development of industrial magnesium alloys using alloying techniques for over a century. After proper alloying, the strength of magnesium can be significantly improved. Magnesium and magnesium alloys have many performance characteristics compared with other materials.

Low density, good specific performance, good shock absorption performance, good electrical conductivity and thermal conductivity, good process performance, poor corrosion resistance, easy to oxidize and burn, and poor heat resistance.

Classification:

According to the processing technology, magnesium alloys can be divided into two categories: cast magnesium alloys and wrought magnesium alloys. The two differ greatly in composition and tissue properties. Compared with cast magnesium alloys, wrought magnesium alloys have higher strength, better ductility, and more style specifications.

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:

High-strength magnesium alloy bars have excellent properties such as small size, high specific strength, good electrical and thermal conductivity, corrosion resistance, beautiful appearance, and easy processing into dense shapes. They are widely used in aviation, aerospace, automobiles, construction, electrical, chemical, and mechanical manufacturing. etc. industries.

High-strength magnesium alloy bar is an indispensable and important structural material for many military and civil aircraft and vehicles.
