Food Grade Aluminum Circle Disc 1050 3003 3105 High Purity Deep Drawing Blank for LED Heat Sink

99.6% High Purity Food Grade Aluminum Circle Disc

Our aluminum circle disc is made from 99.6% high purity aluminum in 1050, 1060, 1070, 3003, 3004, 3105 and 5052 alloys. Produced through DC hot rolling and CC cold rolling lines, each disc is blanked to a strict diameter tolerance of 0.1mm for high precision deep drawing, spinning and stamping production.

Key Selling Points

• 99.6% High Purity Aluminum: High purity substrate delivers stable mechanical performance, excellent formability and a clean food grade surface.
• Food Grade: Complies with food contact requirements, ideal for cookware, frying pans, bakeware and tableware.
• High Thermal Conductivity: 190 W/m.K thermal conductivity supports efficient heat dissipation for LED heat sinks and automotive heat shields.
• Deep Drawing Blank: High elongation above 14% and burr-free edges prevent cracking during deep drawing and spinning.
• Tight Tolerance: Diameter tolerance 0.1mm and uniform thickness reduce trimming waste and improve production efficiency.
