Aluminium and aluminium alloy with flux is generally composed of alkali metal and alkaline earth metal chloride and fluoride.
Aluminum strip, aluminum bar melting point is 660 ℃, generally aluminium casting temperature control at about 730 ℃, and even lower.
Aluminum is located in Ⅲ A group elements in the periodic table, is second only to K, Ca, Na, Mg of an active metal, under the condition of high temperature and oxygen, nitrogen, water vapor, carbon dioxide in the air, etc.
Aluminum ingot is the raw material for smelting and casting pure aluminum and aluminum alloy products (such as aluminum profiles, aluminum alloy castings, etc.).
Now the casting process of aluminum ingot china generally adopts the casting process, that is, the aluminum liquid is poured directly into the mold and taken out after cooling.
Oxidation of metal by oxygen in the air is rust. Aluminum ingot chemically reacts with oxygen to form alumina, which is aluminum rust.
