* Depends on the grade.
1 For thickness >0.65 mm please enquire separately.
2 Material in sheet form available only for standard widths. For other requirements, please enquire seperately.
3 Negative tolerance available on specific agreement prior to ordering.
The specified tolerances on thickness, width and length can be customized to suit individual requirments on specific agreement prior to ordering.
Edge camber:
The edge camber shall not exceed for a measuring length of 1m.
- 0.5mm for a nominal width >150 mm.
Flatness:
Flatness does not apply to materials of width less than or equal to 100mm.
The wave factor expressed as ratio of wave height to wavelength in percentage will be below 1.5%.
Burr level:
The burr level of CR slit edge will be 50 microns max. typically it will be 30 microns.
