[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.
Ningxia Carbon
Coal is the dominant mineral resource in Ningxia. The distribution area of coal-bearing strata in this area is 17,000 square kilometers, accounting for a quarter of the total area of Ningxia. coal has been hailed as black gold, industrial food. Elements that form the coal's organic matter are mainly carbon, hydrogen, oxygen, nitrogen and sulfur, in addition, there is a very small amount of phosphorus, fluorine, chlorine and arsenic and other elements.
