TU00
1 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.
Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Applicability and limitations
Mass fraction wt%; GB/T5231—2012, Table 1, row 1, designation C10100. A dash means unspecified and must not be entered as zero; The combined Cu+Ag minimum must not be split into independent minima for Cu and Ag. Table 1, note a: As, Bi and Sb need not be analyzed, but the supplier must guarantee that the respective limits are not exceeded. This standard covers wrought copper and copper-alloy designations and chemical composition; actual supply of cold-heading wire is not inferred. Table 1 Note b: This value is the copper content, obtained by the difference method when Cu≥99.99%; Te/Se/Mn/Cd upper limit is listed separately according to C10100.
