AS41b Magnesium Alloy AS41b Magnesium Alloy AS41b Magnesium Alloy Price AS41b Magnesium Alloy Properties
Magnesium alloy is an alloy composed of magnesium as the base and other elements added. Its characteristics are: low density (about 1.8g/cm3 magnesium alloy), high specific strength, high specific elastic modulus, good heat dissipation, good shock absorption, greater ability to withstand impact loads than aluminum alloy, and good resistance to organic matter and alkali corrosion. The main alloying elements include aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium. Currently, magnesium aluminum alloy is widely used, followed by magnesium manganese alloy and magnesium zinc zirconium alloy. Mainly used in industrial sectors such as aviation, aerospace, transportation, chemical industry, rockets, etc. In practical metals, magnesium is a lightweight metal with a specific gravity of approximately 2/3 that of aluminum and 1/4 that of iron. It is a lightweight metal among practical metals, with high strength and rigidity.
characteristic
Low density, good specific performance, good shock absorption performance, good electrical and thermal conductivity, good processability, poor corrosion resistance, easy oxidation and combustion, and poor heat resistance.
The stability of magnesium alloy parts is higher than that of high-pressure castings, and the dimensional accuracy of the casting line is higher, which can be used for high-precision mechanical processing.
Magnesium alloy has good die-casting performance, with a wall thickness of up to 0.5mm for die-casting parts. Adapt to manufacturing various types of die-casting parts for automobiles
According to the forming method, it can be divided into two categories: deformed magnesium alloys and cast magnesium alloys.
1. Alloy name
The alloy name of magnesium alloy is based on the main added alloying elements and their percentages.
2. Composition of main alloys (ASTM specifications)
