Az31b Aluminum Magnesium Alloy Bar ASTM Mg Wrought Alloy

Good Conductivity High Strength Magnesium Alloy Bar For Automobile Industry

Introduction:

Compared with cast magnesium alloys, wrought magnesium alloys have greater development potential. Through the control of material structure and the application of heat treatment processes, wrought magnesium alloys can obtain higher strength, better ductility and more diverse mechanics. performance, so as to meet the application requirements of diverse engineering structural parts. Wrought magnesium alloys often need to be heated to a certain temperature and processed by hot forming techniques such as extrusion, rolling and forging.

Features:

• Low density, the density of pure magnesium is only 1.74g/cm3, which is about 2/3 of aluminum and 1/4 of steel, close to the specific gravity of engineering plastics. It is the lightest structural alloy, which can effectively reduce the weight of components and save energy. energy consumption;
• 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 requiring good heat dissipation performance;
• It has good damping performance, strong absorption capacity and strong shock absorption, which can be used in situations with severe vibration, and 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;

Classification:

According to the classification of processing technology, magnesium alloys can be divided into two categories: cast magnesium alloys and wrought magnesium alloys. There are great differences in composition and tissue properties between the two. Compared with cast magnesium alloys, wrought magnesium alloys have higher strength, better plasticity and more style specifications.

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, automobile, construction, electrical, chemical, and machinery manufacturing. and other industries. High-strength magnesium alloy bars are an indispensable and important structural material for many military and civil aircraft and vehicles.

Magnesium alloy die castings are mainly used to manufacture automobile instrument panels, seat frames, transmission housings, steering wheel control system components, engine parts, door frames, wheel hubs, brackets, clutch housings, body brackets, etc.
