Aluminum Electropolishing
Aluminum electropolishing involves removing a very thin layer from the metal's surface. While Bama has the technology to perform this process, it is not applicable to mass-produced items. Custom projects can be evaluated based on client needs.
Process Details
Bama performs aluminum electropolishing within its production site.
Though typically done on stainless steel, this process is also applied to aluminum due to its numerous benefits.
Aluminum electropolishing involves removing a thin layer from the metal surface, eliminating all types of burrs and roughness and resulting in a perfectly smooth and polished surface on a microscopic level.
Advantages
Aluminum electropolishing not only smooths surfaces but also provides several additional benefits.
Primarily, it enhances the aesthetic appearance of aluminum. The process also significantly increases the material's corrosion resistance, expanding its applications and extending the object's lifespan.
Aluminum electropolishing is even more effective when preceded by degreasing, pickling, and passivation processes.
These preliminary steps ensure a deeply cleaned (degreasing and pickling) and protected (passivation) surface.
The technique used for aluminum electropolishing is immersion.
The object is placed in a tank filled with a chemical solution, usually composed of sulfuric and phosphoric acids, and connected to a positive pole.
A current passes through, causing surface ions to detach and smooth out any unevenness.
This process does not reduce the object's volume, as the removed layer is only 5 to 15 microns thick.
As with stainless steel, this phase is particularly useful for creating products that are easy to clean and corrosion-resistant, ideal for pharmaceutical, chemical, medical, and food industries.
