Standard aluminum is an aluminum ingot, containing 99.7% aluminum and registered on the London market. Aluminum oxide (AlO) is a high-hardness compound with a melting point of 2054 and a boiling point of 2980. It is an ionic crystal that can be ionized at high temperatures. It is commonly used in the manufacture of refractory materials. Industrial alumina is made from alumina (Al2O 33H2O) and diaspore. For alumina requiring high purity, chemical methods are generally used to prepare it.
Raw aluminum is collectively referred to as electrolytic aluminum in market supply and is the raw material for the production of aluminum materials and aluminum alloy materials. Aluminum is a metal with low strength and good plasticity.
In addition to using some pure aluminum, it is formulated into alloys in order to improve strength or comprehensive performance. Adding an alloy element to aluminum can change its structure and properties, making it suitable for various processing materials or casting parts. Commonly added alloying elements include copper, magnesium, zinc, and silicon.
