Magnesium Alloy Product Datasheet
Embedded Files
A wrought magnesium alloy offering good properties:
Light weight, high specific strength, high specific modulus of elasticity, impact resistance, wear resistance, good processing performance, fast heat dissipation, certain corrosion resistance and dimensional stability, easy to recycle; good weldability, good thermal conductivity, good electrical conductivity, non-magnetic, good shielding and non-toxic characteristics.
the following types of products:
Due to the aforementioned characteristics, AZ31B material has been successfully used to produce various products including:
Aircraft fuselage, aircraft hub, rocker arm, and hatch
Missile instrument compartment, tail compartment, and engine bracket
Various engine gear cases, oil pumps, and oil pipes
Auto parts, wheel hubs, parts housings, communication equipment, clutch housings, valve covers, gearbox bodies, cylinder heads, air conditioner housings, steering wheels, seats, steering brackets, and brake brackets
3C products such as mobile phones, cameras, notebook computer casings, and navigator casings that meet the requirements of the electronics and computer industry for RFI and EMI shielding
Dockboards, grain shovels, and gravity conveyors
Glasses, engraving, hot stamping plates, shoe molds, radiators, outdoor products, and stroller frames
Various tool structures, luggage, ladders, textile machinery structures, concrete tools, and machinery vibration damping structures.
AZ31B wrought magnesium alloy material is mainly available in the form of sheets, profiles, and bars. The chemical composition of AZ31B and other magnesium alloys is shown in Table 1, as specified by GB/T5153-2016.
In addition to the above-mentioned round ingots, we can also provide hot extruded rods, hot extruded profiles, hot rolled or cold rolled thin plates and strips, welding wire, electrodes, and customized products. Based on the physical and mechanical properties of AZ31B, it is suitable for products such as complex-shaped forgings, die forgings, alloy powders, alloy particles, and structural components under medium load.
Machinability
It has good machinability, but It is combustible in powder form, and should be handled with care during processing. Cutting fluid should be used during processing, and good ventilation ensured. Mechanics should wear appropriate protective equipment and continuously monitor the operation.
Forming
Can be formed by preheating at about 260°C (500°F).
welding
Welding can be performed using metal arc welding and gas tungsten arc welding techniques.
Excellent weldability using gas shielded arc.
Annealing
Stress relief at about 149°C (300°F) for 30 to 60 minutes followed by air cooling. Full annealing can be done at about 344°C (650°F) followed by slow cooling in the furnace. Magnesium alloys should maintain a neutral atmosphere in the heating furnace or pass a protective gas to prevent combustion.
Surface treatment
AZ31B can be protected with various coatings including
Chromizing, Anodizing, Electroplating, Electronic Coating, Paint, and Plasma.
Plasma Electrolytic Oxidation (PEO).
