Aluminum disc for lampshade
Aluminum disc for lampshades refer to aluminum discs used to make lampshades.
Due to the special properties of aluminum discs, they are very suitable for making lampshades, lamp cover.
We have anodized quality aluminum discs, and painted aluminum discs for making different lamp shade, such as recessed lighting, high bay Industrial lighting, low bay industrial lighting, low bay Industrial lighting, traffic light reflectors, sports lighting.
Anodized aluminum disc for lampshade
Some of the current applications for our aluminum circle products are：recessed lighting, high bay industrial lighting, low bay industrial lighting, street lighting, traffic light reflectors, sports lighting.
Alloys of lampshade aluminum disc
Aluminum disc for lampshades generally do not have high requirements on material strength, but do have certain requirements on reflectivity and quality.
Therefore, 1000 series aluminum discs are the best choice.
1100 aluminum cricle disc
1000 series aluminum alloy has the advantages of low density, mature production technology and low price.

Production process and quality control
1. Manufacturing process
The production of aluminum discs mainly includes the following steps:
Melting and casting: Aluminum ingots and alloy elements are smelted and then DC cast to form aluminum slabs.
Hot rolling and cold rolling: The billet is thinned to the target thickness (0.3-6.0 mm) through multiple rolling passes.
Punching and annealing: After the disc is punched, it is annealed to eliminate internal stress and improve ductility.
2. Key quality indicators
Dimension tolerance: Diameter range 20-1500 mm, thickness error controlled within ±0.08 mm.
Surface treatment: No scratches, oxidation spots, and burrs on the edges are required to ensure the adhesion of subsequent coatings.
