4, requirement
4.1 brands, condition, classification

The brand of the product, condition, classification should accord with a watch the regulation of 1

Express 1
Standards of alloy name state (Mm)
Ply width length coils internal diameter Φ %
1100, 8011, 8111, 3003, 5052H14, h24, h16, h26, h180.2-0.350-1500500-2000200
Note: 1, be like need other alloy, condition and norms board strip, both sides of supply and demand can talk things over separately and make clear in the contract.
2, when offerring money with 3003 alloy, should add after alloy brand " S " namely " 3003S " .

4.2 mark give typical examples
With the H26 position that 8011 alloy create, ply is 0.23mm, width is for the strip mark of 610mm:
Take 8011H26 0.23*610*C EL/*273-1999

4.3 chemical composition

Board, the chemical composition of strip should accord with GB/T3190 regulation.

4.4 over all dimension reach tolerance
