Review the complete catalog
The published General Clad grade directory includes 21, 25, 30, 32, 35, 40, 53 and 55% IACS. A discussion of three classes does not define the whole portfolio.
The 40% IACS round-wire listing gives 0.06–5 mm diameter; the other seven grade records give 0.06–6.54 mm. These are catalog references; confirm the current combination of diameter, condition and performance for your request.
