Foreword
The revision of this standard adopts ISO/DIS 24373:2007 "Welding
consumables - Solid wires and rods for fusion welding of copper and copper
alloys - Classification" (English version).
This standard was re-drafted in accordance with ISO/DIS 24373:2007.
Considering the actual situation of copper and copper alloy wires and rods in
China, the following technical content modifications have been made to
ISO/DIS 24373:2007:
- DELETE the normative references ISO 544, ISO 4063, ISO 14344, ISO 31-
0:1992;
- ADD Appendix A and Appendix B, brief description of welding wire and
comparison table of main international standard models;
- ADD Tables 2, 3, 4, Figure 1.
For ease of use, this standard also makes the following editorial changes:
- CHANGE the standard name to "Copper and copper alloy wires and rods";
- In terms of standard structure, ADD the inspection rules, markings, quality
certificates;
- CHANGE "this international standard" into "this standard";
- USE the decimal point "." to replace comma "," which functions as a decimal
point;
- DELETE the foreword of international standard.
This standard is a revision of GB/T 9460-1988 "Welding wire and rods of copper
and copper alloys". Compared with GB/T 9460-1988, the main revisions are as
follows:
- The method of classification of welding wire and model division adopts
ISO/DIS 24373:2007;
- The chemical composition of the welding wire is consistent with the
requirements of ISO/DIS 24373:2007; add 18 models of welding wire;
- ADD the warpage and relaxation diameter requirements of welding wire;
- MAKE adjustment of the size of welding wire and packaging method
accordingly in accordance with the requirements of ISO/DIS 24373:2007;

alloys
3 Classification and model
3.1 Classification of welding wire
Welding wire is divided into 4 categories according to chemical composition:
copper, brass, bronze, nickel-copper.
3.2 Model classification
Welding wire’s model is divided by chemical composition (see Table 1).
3.3 Model designation
The welding wire’s model consists of three parts. The first part is the letter "SCu",
which means copper and copper alloy welding wire; the second part is a 4-digit
number, which indicates the welding wire’s model; the third part is an optional
part, which indicates the chemical composition code. For a brief description of
