The properties of magnesium
Magnesium is a kind of qualitative light, silver into strips, or the neutral hardness of powder metal elements, burning with very bright white flame, used for alloy in the field of architecture, fireworks, flash or a Molotov cocktail. Atomic number 12; Atomic weight of 24.312. Melting point of 6490 c; Boiling point of 10900 c; Specific gravity 1.74 = 200 c (T); Valence 2, silvery white in color.
Magnesium alloy characteristics
Light weight: the proportion of magnesium alloy is 2.7, aluminum 2/3, iron 1/4.
The vibration absorption is good: magnesium alloy has good vibration absorption. In the absorption of vibration, reduce noise and prolong the life of the machine has the effect of.
Good dimensional stability: Die Casting with AZ series alloy melt in the range of about 435 degrees Celsius, in the initial stage with a small shrinkage phenomenon, the organization will not change after the solidification. Magnesium alloy products in the case of long heating to 100 degrees Celsius, the size of the shape is almost no change. It can be seen that the dimensional stability of the product is very good.
Absorption of radiation is good: the conductive properties of magnesium alloy is very good, so the performance of absorbing electromagnetic wave is excellent. At present, the majority of mobile phone method is used in the plastic shell on the conductive paint spray, process control is not good, the partition effect is not ideal.
High strength:compared with iron, magnesium alloy and other alloy Aluminum Alloy, unit weight of strength (strength) than the best intensity is about 1.5 times that of steel.
Environmental protection: magnesium alloy is harmless to the environment, the world considers green materials in twenty-first Century.
