Magnesium alloy is a commonly used material that brings good results, but it is important to know its advantages to ensure normal use in the later stage. And what material is magnesium alloy.
A. What material is magnesium alloy:
Magnesium alloy is an alloy based on magnesium with the addition of other elements such as aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium. Magnesium alloy has advantages such as low density, high strength, high elastic modulus, good heat dissipation, and good shock absorption. It also has a greater ability to withstand impact loads than aluminum alloy, and has good resistance to organic matter and alkali corrosion. In addition, magnesium aluminum alloys are widely used in industrial sectors such as aviation, aerospace, transportation, chemical engineering, and rockets.
B. What are the characteristics of magnesium alloys:
1. Dimensional stability: When taken out of the mold, the product only requires a small amount of casting residual stress, so annealing and stress relief treatment are not required. However, under load, this metal can also exhibit good creep resistance.
2. Cutting performance: Magnesium has better processing and cutting characteristics, making it the easiest material to machine.
3. High shock-absorbing performance: Magnesium has excellent hysteresis and shock-absorbing performance, which can absorb vibration and noise. This is very important for reducing noise propagation and preventing impact and dent damage when used as equipment casings.
4. Lightweight: Under the same stiffness, one pound of magnesium is equivalent to 1.8 pounds of aluminum and 2.1 pounds of steel in strength. Adding magnesium together can make the parts messy like aluminum, but the weight is only one-third lighter than the latter. The above characteristics are crucial for some modern portable products. As for the vehicle, this feature will significantly reduce its starting inertia and save fuel consumption.
5. High heat dissipation: Magnesium alloy has high heat dissipation, suitable for today's densely planned electronic products. Magnesium alloy has better thermal conductivity than general structural metals and can be used for rapid dispersion of heat sources.
