Aluminum seamless tubes are widely found in production of optical lens barrels, which are typically used in cameras, microscopes, telescopes and projectors.
This product is made by utilizing 5000 series aluminum alloy that is featured by good machinability, and subjected to anodizing surface treatment to provide superior look. Indirect extrusion process is carried out for seamless tube production.
These lenses are constructed with 6061-T6 aluminum alloy, featuring good machinability and high resistance to corrosion. The surface is subjected to anodizing surface treatment to provide superior look.
6061 and 6063 aluminum alloys are mainly used for their excellent machinability, corrosion resistance and welding performance. The surface is subjected to anodizing surface treatment to provide superior look.
