TBE0.6-2.5

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/T 5231-2012, Table 2, row 4, designation C17500; scanned original PDF, PDF physical page 6 (printed page 4). Where Cu is marked as balance, no numerical range is invented; a dash means unspecified and is not replaced with zero. Clause 2.2: single impurity values in the table are maxima. Manufacturer supply and compliance with this standard's chemical composition require separate confirmation. Note a to Table 2 defines high-copper alloys as containing copper between 96.0% and 99.3%; this does not guarantee cold-heading wire supply. The total of table-listed impurities is ≤1%; this is not a maximum for each individual unlisted element.
