Reduced iron powder application for iron additive tablets in aluminum alloys

Iron in Al - Cu - Mg - Ni - Fe in the forging of aluminum alloy, silicon in Al - Mg - Si is wrought aluminium and in Al - Si electrode and aluminum silicon alloy casting, all of the alloy elements and in the aluminum alloy, silicon and iron is a common impurity elements, have obvious influence on alloy properties they mainly exist in FeCl3 and free silicon in silicon is greater than the iron, the formation of beta FeSiAl3 (or Fe2Si2Al9) phase, while the iron is greater than the silicon to form alpha Fe2SiAl8 (or Fe3Si2Al12)When the ratio of iron and silicon is not at the time, it will cause cracks in the casting, and the high content of iron in the cast aluminum will cause brittleness in the casting.

Aluminum alloy additives, also known as aluminum alloy flux;This product is a gray powder additives, used to adjust the content of the different type aluminum alloy iron used instead of intermediate alloy, can reduce melting temperature can simplify aluminium alloy smelting process, save energy and raw materials, reduce production cost, improve product quality, and has a high metal content, small volume, convenient for storage and transportation and then use, etc.
