The functions of high-purity aluminum mainly include the following aspects:

Corrosion resistance: High-purity aluminum has a strong characteristic of resisting external reactants, that is, it has a strong corrosion resistance, which is about 9 times more than ordinary raw aluminum.
Reflectivity: High-purity aluminum has high light reflectivity.
Conductivity: High-purity aluminum has excellent conductivity.
Thermal conductivity: High-purity aluminum has good thermal conductivity.
Superconductivity: Aluminum with a purity of more than 99.99% becomes a superconductor at extremely low temperatures (1.1~1.2K).
Processing performance: The higher the purity of aluminum, the lower its tensile strength and yield strength, the greater its ductility, the stronger its softness, and the higher its toughness.
Electronic paste: High-purity aluminum can be used to make conductive coatings and electronic pastes for photovoltaic cells.
Medicine and pesticides: High-purity aluminum is also used in the fields of medicine and pesticides.
Chemical catalysts: High-purity aluminum can be used as chemical catalysts, antiperspirants, etc.
Superhard materials: High-purity aluminum can be used to make superhard materials.

Anode foil for electrolytic capacitors: Industrial high-purity aluminum is mainly used as anode foil for electrolytic capacitors.
Integrated circuit wires: Industrial high-purity aluminum is used to make integrated circuit wires.
Vacuum evaporation materials: Industrial high-purity aluminum is used to make vacuum evaporation materials.
Stable conductors for superconductors: Industrial high-purity aluminum is used to make stable conductors for superconductors.
Disk alloys: Industrial high-purity aluminum is used to make disk alloys.
Matrix metal for high fracture toughness aluminum alloys: Industrial high-purity aluminum is used to make matrix metal for high fracture toughness aluminum alloys.
