Magnesium alloy die castings, magnesium alloy products
1. Magnesium
Magnesium (Mg), the 12th element on the periodic table, is a basic earth metal, ahead of aluminum (AL).Magnesium is one of the most abundant light metallic elements on earth, and is widely found in magnesite (magnesium carbonate), dolomite (calcium magnesium carbonate) and carnallite (magnesium potassium chloride hydrate).
2. Magnesium alloy
As the lightest structural material, magnesium alloy has low specific gravity (about 23% of steel and 64% of aluminum) and high specific strength and stiffness.Good thermal and electrical conductivity;With good electromagnetic shielding, damping, shock absorption, and cutting and die casting process performance.
Weight: magnesium alloy is 36% lighter than aluminum alloy, 73% lighter than zinc, and 77% lighter than steel.
Specific strength: magnesium alloy is equivalent to aluminum alloy and steel, much higher than fiber reinforced plastics;
Wear resistance: the wear resistance of magnesium alloy is much higher than that of die-cast aluminum alloy A380;
Damping performance: magnesium alloy is 30 times higher than aluminum alloy;
Others: magnesium alloy is 200 times higher than plastic in thermal conductivity, thermal expansion performance is only half of the plastic.
3. Application of magnesium alloys
As one of the metal structural parts with the smallest density at present, magnesium alloy is widely used in aerospace industry, military industry, transportation (automobile, aircraft, motorcycle, bicycle), 3C and other fields.
Europe is currently using and development of magnesium alloy automobile parts for more than 60 kinds of North America are using and are working on the magnesium alloy automobile parts has reached more than 100, ford motor company bike USES 45 mg alloy die casting, Chrysler with 20 mg alloy die casting, bike with magnesium amount to 20-40 kg.Ford has used up to 103kg of magnesium alloy parts per car in the 2000 concept model.Ford motor Co. plans to increase the amount of magnesium it USES in each vehicle to 113 kilograms over the next 20 years, according to a report from before 2010.
According to the report, Japan has successfully processed the automobile top box of flame retardant magnesium alloy material (length 200mm × width 670mm × height 270mm, weight about 12.5kg).Compared with the FRP (reinforced plastic) products on the market, the weight can be reduced by about 25%.
At present, magnesium alloy die casting products are used in automobile instruments, seat frames, directional operating system components, engine covers, gearboxes, intake pipes, wheel hubs, engines and safety components.
Magnesium alloy auto parts
advantages of magnesium alloy auto parts
1. Light weight: magnesium alloy is 1/3 lighter than aluminum alloy and 77% lighter than steel, which is the lightest structural metal material in common use.
2. High specific strength and strong rigidity: in the same shape, the rigidity of magnesium alloy products is more than 10 times that of plastics.Under the same rigid conditions, a pound of magnesium is as strong as 1.8 pounds of aluminum and 2.1 pounds of steel.If ABS plastic is replaced with magnesium alloy, the weight of the product can be reduced by 36% and the thickness can be reduced by 64%.
3. Impact resistance: excellent damping shock absorption performance: magnesium alloy resistance to vibration and reduce noise performance is excellent, 10-50 times of aluminum alloy.Magnesium alloy is strong enough to withstand impact, and its thickness is only 1/3 of that of plastic under the same resistance.
4. Good creep resistance.
5. In line with environmental protection: can be completely recycled.
6. Excellent die-casting formability: die-casting can be used to make parts with complex shapes and shell parts with ultra-thin thickness up to 0.45mm thick (ABS plastic 1.2-2mm, aluminum alloy 1.5-2mm).
Can be customized according to customer demand a variety of auto parts.
