Az31b Billet Magnesium In Vehicle Structural Parts

Competitive Lightweight Material High Strength Magnesium Alloy Used In Communication Products

Introduction:

Magnesium alloy is the lightest practical metal that can be used for structural materials. Magnesium alloy has significantly better strength and stiffness than plastic, and better impact resistance than aluminum alloy. It is widely used in automobiles, communication electronics and so on. The automobile industry is the industry with the most applications of magnesium alloys and the best prospects.

Classification:

Magnesium alloys are generally classified in three ways: chemical composition, molding process, and whether or not they contain modifier zirconium.

• Based on chemical composition, based on five main alloying elements Mn, Al, Zn, Zr and rare earths: Mg-Mn, Mg-AL-Mn, Mg-Al-Zn-Mn, Mg-Zr, Mg-Zn-Zr , Mg-Re-Zr, Mg-Ag-Re-Zr, Mg-Y-Re-Zr.
• 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.
• Zirconium has a strong grain refining effect on magnesium alloys. According to whether the magnesium alloy contains zirconium or not, it is divided into two categories: zirconium-free magnesium alloy and zirconium-containing magnesium alloy.

Features:

• The specific strength and specific stiffness are large, and the specific strength of magnesium alloys is not only higher than some high-strength steels but even higher than aluminum alloys;
• Good thermal conductivity, large expansion coefficient, low elastic modulus, slightly inferior to general aluminum alloys, 300 times that of general engineering materials, and low temperature dependence, can be used to manufacture electronic products that require good heat dissipation performance;
• It has good damping performance, strong absorption capacity, and strong shock absorption. It can be used in occasions with severe vibration, and it can enhance the safety and comfort of automobiles when used in automobiles;
• Magnesium alloy is a non-magnetic shielding material with good electromagnetic shielding performance and strong anti-electromagnetic wave interference ability, which can be used in communication products such as mobile phones;
• Has good machinability;
• Excellent casting performance, high casting rate, easy to form complex shapes, good appearance and texture, can be used to make notebook computers, cameras and other shells;
• The shrinkage rate of magnesium alloy wire is small, the size is stable, and it is not easy to change due to environmental changes (relative to engineering plastics);

Application:

Structural parts with magnesium alloy as the base material are mainly used in special environments with strict requirements on the strength of structural parts, light equipment weight (design weight is smaller than aluminum alloy), high electromagnetic shielding requirements, shock absorption, compression resistance and impact resistance. 

Such as: aviation parts, aerospace electronic equipment structural parts, unmanned aerial vehicle structural parts, reinforced computer structural parts, medical equipment structural parts, communication equipment structural parts, heat sinks, shielding boxes, electronic disks, heat conduction plates, cameras, GPS positioning equipment, Radar receiving equipment, various handles, control panels, switches, etc.
