To guarantee its non-stick properties and deep drawing properties,

The flatness standard of aluminium discs will strictly follow the table below:

thickness/mm Total unflatness
d/D
Partial unflatness (R> 300mm)
d/R
> 0.2~0.5 negotiable
> 0.5~3.0 ≤ 0.5% ≤ 0.4%
> 3.0~6.0 ≤ 0.4% ≤ 0.35%
> 6.0~12.0 ≤ 0.4% ≤ 0.3%
> 12~50 ≤ 0.4% — —
> 50~150 ≤ 0.3% — —
Note: D is the diameter of circle, R is random chord, d is the wave height
