What distinction do pure aluminium ingot and aluminium alloy have

Pure aluminum ingots and aluminum alloy are different as follows:

Pure aluminum ingots: aluminum exists in the surface, in addition to iron (Fe) content of the second metal element, since the invention of electrolysis, human beings from the surface to obtain bauxite, refined high purity (99.7% or more) of aluminum, is pure aluminum ingots. If directly used for casting, it has good toughness but no strength and poor physical properties.

Alloy ingot: pure aluminum and recycled aluminum as raw materials, according to international standards or special requirements to add other elements, such as: GUI (Si), copper (Cu), magnesium (Mg), iron (Fe)... , improve pure aluminum in casting, chemical and physical properties of the insufficient allocation of alloy. Suitable for casting and can give good casting performance.
