3. Why Choose 3003 Alloy as the Core Material?
-
Food-Grade Safety: 3003 is a manganese-based alloy with no risk of heavy metal leaching.
-
Superior Deep Drawing: Our 3003-O discs exhibit excellent ductility, preventing bottom cracking during high-speed stamping.
-
Uniform Heat Distribution: Aluminum‘s thermal conductivity prevents “hot spots,” ensuring consistent cooking results.

6. FAQ: Frequently Asked Questions
Q1: What is the difference between 3003 and 1060 discs?
A: 3003 has higher hardness and corrosion resistance due to Manganese, making it the standard for coated cookware. 1060 is softer and suited for simple utility items.
Q2: Can I get a custom diameter (e.g., 1005mm)?
A: Yes. We specialize in custom blanking sizes to minimize your scrap rate.
Q3: Are samples available?
A: We provide 3-5 free sample discs for your engineering team to verify drawing performance.
