The difference between pure aluminum ingot and alloy aluminum ingot
[China Aluminum Industry Net] Pure aluminum ingots: Aluminum is the metal element that exists in the ground surface, with the exception of iron (Fe), which ranks second in the world. After the invention of the electrolytic method, humans obtained bauxite from the surface and extracted high purity. (99.7% or more) aluminum is a pure aluminum ingot. If used directly for casting, the toughness of the casting is good but it has no strength and physical properties are not good.
Aluminum alloy ingot: pure aluminum and recycled aluminum as raw materials, add other elements in accordance with international standards or special requirements, such as: (Si), copper (Cu), magnesium (Mg), iron (Fe) ..., improve the pure aluminum Castability, chemical and physical properties of the alloy formulated. Suitable for casting and can make castings perform well.
