What are the differences between aluminium magnesium alloy, aluminum alloy and plastic steel?

Answer:

In the fireworks production process plays a very important role in reducing agents, but also as a white light agent and lighting agentMagnesium 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.
An alloy based on aluminum. The main alloying elements are copper, silicon, magnesium, zinc and manganese. The minor alloying elements are nickel, iron, titanium, chromium, lithium and so onAluminum alloy low density, but relatively high strength, close to or higher quality steel, plastic good, can be processed into various profiles, with excellent conductivity, thermal conductivity and corrosion resistance, widely used in industry, the use of only steelAluminum Alloy divided into two categories: cast Aluminum Alloy, cast under; deformation Aluminum Alloy, can withstand the pressure processing, mechanical properties than cast. Aluminum Alloy material can be processed into various forms and specifications. Mainly used in the manufacture of aviation equipment, daily necessities, building doors and windows.
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.Have a great impact on the quality of production safety and product content of magnesium, aluminum magnesium alloy standard in all about how many of the fireworks aluminum content of 50%. activity. But now the production of magnesium alloy for many enterprises and private enterprises, in recent years the aluminum ingot is more expensive than the magnesium spindle, driven by interests, are not in accordance with GB production. Now in the magnalium powder the aluminum content is generally less than 50%, some low aluminum content to increase the properties of 40%. magnesium alloy content makes the properties close to magnesium, so the pyrotechnic impact sensitivity and friction sensitivity increase, pyrotechnics is more sensitive, thereby increasing the risk. We may use the following chemical mechanism to test the content of magnesium alloy in aluminum.
