What is magnesium aluminum alloy and what is its use?

Answer:

Magnesium ingot and aluminium in the above 1150K, reaction of aluminum and oxygen in the air to form a-Al2O3, the crystal chemical properties of alumina is inert, a barrier and isolation. Less than 1150K, in the B-Al2O3 and the crystal reaction with acid magnesium alloy not inner protection.
Magnesium alloy is magnesium ingots and aluminum ingots in protective gas melted into. For a long time about the structure of Al Mg alloy with two kinds of argument. One theory is that magnesium alloy is a simple physical mixture; another is magnesium alloy changes inside the crystal structure, is not a simple physical mixture.
Magnesium alloy molecular formula: Mg4Al3 molecular weight: 178.22 color is brown, the proportion is about 2.15g/cm3, the melting point of 463 DEG C, when combustion temperature reaches 2000 DEG -3000 DEG. In fireworks production process plays a very important role in reducing agent, can also be used as white lighting agent and agent.
