What is high purity aluminum

Purity means that the purity of aluminum is greater than 99.8%. This kind of pure aluminum is called high-purity aluminum, highly pure aluminum.

High-purity aluminum is produced by using high-quality crystalline aluminum liquid as raw material and then refining this refined aluminum liquid by directional solidification.

High-purity aluminum can be of different types:

Sub-ultra-high purity aluminum has an aluminum content of 99.95%~99.9959%.

Ultra-high purity aluminum has an aluminum content of 99.996%~99.999%.

Ultra-high purity aluminum has an aluminum content of more than 99.999%.

The color of high-purity aluminum is silver-white, the surface is very smooth, there are very clear crystal lines, and there are no impurities.

High-purity aluminum has very low deformation resistance, that is, it is very easy to deform.

High-purity aluminum also has a very high conductivity, that is, it conducts electricity very quickly and very well, and consumes very little power.

High-purity aluminum also has good plasticity, so it is easy to be pressed and extruded.

High-purity aluminum is mainly used in scientific research, electronic industry, chemical industry, manufacturing high-purity aluminum alloys, laser materials and some other special uses.

High-purity aluminum is generally supplied in semi-circular ingots or long plate ingots. The weight of each semi-circular ingot is not less than 45 kg, and the weight of each long plate ingot is not more than 25 kg. The cross-sectional size of the long plate ingot is generally 200mm×65mm, and the length is not more than 600mm.
