Foreword

This revised standard adopts the International Standard ISO 9724.1992 "nickel and nickel alloy wire and drawing a blank." The number of standard clauses ISO 9724.1992 reg number of the standard controls see Appendix A, specific technical differences between this standard, see Appendix B. This standard replaces GB/T 3120-1982 "Nickel wire" and GB/T 3121-1982 "power vacuum devices with nickel and nickel alloy wire." The standard Registration and GB/T 3120-1982 and GB/T 3121-1982 compared to the main changes are as follows. --- New addition N5 (NW2200), N7 (NW2201), NCu30 (NW4400), NCu30-3-0.5 (NW5500), NMn3, NMn5 six grades of nickel alloy products. And an increase in their respective technical requirements. --- The maximum diameter of the wire (on the margin) increased from 6mm extended to 10mm. --- Increasing the winding wire torsion testing and test, and the test methods and results of the corresponding regulations. --- Wire dimensions and tolerances identical with ISO 9724. The Standard Appendix A, Appendix B is an informative annex. The standard proposed by China Nonferrous Metals Industry Association. This standard Nonferrous Metals by the National Standardization Technical Committee. This standard by the Shenyang-Copper Industry Co., Ltd., China Nonferrous Metals Industry Standards and Metrology and Quality Institute of Jinchuan Group Ltd negative Responsible for drafting.
