Foreword
This Standard adopts the Japanese industrial standards JIS H3100-2006 Copper and Copper Alloy Sheets, Plates and Strips and JIS H3110-2006 Phosphor Bronze and Nickel Silver Sheets, Plates and Strips by modification; adopts the EU standard BS EN 1652:1998 Copper and Copper Alloys - Plate, Sheet, Strip and Circles for General Purposes by reference.
This Standard serves as a replacement of GB/T 2059-2000 Strips of Copper and Copper Alloys, GB/T 2067-1980 Tin-zinc-lead-bronze Strips, GB/T 2069-1980 Aluminum-copper-nickel Alloy Strips, GB/T 11089-1989 Leaded Brass Strips for Special Purpose and GB/T 15714-1995 Brass (H65) Strip for Welded Tube.
In comparison with GB/T 2059-2000, GB/T 2067-1980, GB/T 2069-1980, GB/T 11089- 1989 and GB/T 15714-1995, the main changes are as follows:
---Four designations (H63, H85, QSn8-0.3 and BZn18-17) are added. In addition, Designation C2300 in JIS H3100-2006 and Designation CuZn15 in the EN
standard are used to specify the mechanical properties of Designation H85; Designation C5212 in JIS H3110-2006 is used to specify the mechanical
properties of Designation QSn8-0.3; Designation C7521 in JIS H3110-2006 is used to specify the chemical composition and mechanical properties of
Designation BZn18-17;
---For pure copper, the extra-hard (T) state is added; the mechanical properties of the hard (Y) state are accordingly modified;
---The elastic-hard (TY) state is added to H70, H65, H65 and QSn6.5-0.1; JIS H3100-2006 and JIS H3110-2006 are used to modify the tensile strength values; ---The lower limit of the available thickness of the strip is modified from ?€?0.05 mm?€? to ?€?greater than 0.15 mm?€?; for pure copper and ordinary brass, the upper limit of the width of strip with a thickness of 0.5 mm ~ 3.0 mm is expanded from ?€?1,000 mm?€? to ?€?1,200 mm?€?;
---The overall dimensions and tolerances shall comply with the stipulations of GB/T 17793;
---The hardness test is modified from ?€?an optional reference item?€? into ?€?a routine inspection item?€?; it is also stipulated that ?€?choose either tensile test or hardness test, and when there are no special instructions, provide tensile test?€?; ---The measurable thickness of the tensile test is modified from not less than ?€?0.3 mm?€? into not less than ?€?0.2 mm and 0.15 mm?€?; the thickness requirements for the hardness test are deleted (that is, all specifications may be tested); Strip of Copper and Copper Alloy
