GB/T 26007-2017Copper alloys strip and foil for springs and connectors (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 26007-2010 "Copper band for elastic elements and connectors".

The main technical changes compared to GB/T 26007-2010 are as follows.

--- "1/4 hard (Y4), half hard (Y2), hard (Y), special hard (T), hard (TY)" state change to "1/4 hard (H01) 1/2 hard (H02), hard (H04), hard (H06), elastic (H08) ";

--- Thickness range from "0.1mm ~ 1.5mm" expanded to "0.07mm ~ 2mm";

--- width range from "3mm ~.200mm" expanded to "6mm ~ 620mm";

--- increased the symbol of the alloy;

--- increased the H62, H66, H68 grades and related regulations;

- the provisions of "the method of analysis of chemical composition of strip material in accordance with YS/T 482, YS/T 483" are added;

--- increased the "strip size measurement according to GB/T 26303.3 provisions" requirement;

--- "the preparation of the sample according to the provisions of YS/T 815" provisions;

- the addition of the "sampling method according to the provisions of YS/T 668" requirement;

--- to improve the "strip side of the curvature of the" requirements;

--- to improve the "strip width tolerance" requirements;

--- to improve the "strip thickness tolerance" requirements.
