Foreword
This standard is GB/T 13808-1992 "copper and copper alloy extruded rod" for the industry to adjust the revised standard and GB/T 13809-
1992 "Copper and copper alloy rectangular stick" extruded rod portion included in the standard. Revision, with reference to the Japanese Industrial Standard JISH3250.1992
"Copper and copper alloy rods."
This standard and GB/and GB/T 13809-1992, compared T 13808-1992 main changes are as follows.
--- Increased QA110-5-5, BFe10-1-1, QSn4-0.3 four grades;
--- Adjust some of the product specifications. relaxed class copper and HSn62-1, HMn58-2, HFe59-1-1, H62, HPb59-1,
QAl9-2, QAl9-4, QAl10-3-1.5, QAl10-4-4, QSn4-3, QSn7-0.2, QSn6.5-0.1, QSn6.5-0.4 round
The upper limit for the diameter of the rod; T2, T3 square, hexagonal rod diameter lower limit for the "30mm" adjusted "20mm"; increase
The QAl9-2 grades square, hexagonal rods SPECIFICATIONS.
--- Rod diameter to allow deviation margins expressed as a percentage;
--- Roundness tolerances equivalent diameter of the rod, to the margins of tolerance;
--- Added "end cut allow no more than 3mm cut slope" requirement;
--- Diameter of not more than 120mm rod straightness were tightened, and the shaped rod straightness were prescribed;
--- The "When selecting the hardness test, tensile test results for reference only" to "When selecting the hardness test, tensile test is not";
--- Tensile test specimens long deleted provisions;
--- Increased TU1, TU2, TP2, H59, H80, QSi3.5-3-1.5, QCr0.5 grade mechanical performance requirements;
--- H96 Elongation rate of "33%" to "35%;
--- Increased diameter (on the margin) is not greater than QAl9-2 grades Brinell hardness of 45mm;
--- The grades QAl10-5-5 QAl10-4-4 and performance requirements into one file, while the Brinell hardness from "170 to 240"
Changed to "170 to 260";
--- Remove the "rod diameter of less than 16mm can not Brinell hardness test" requirement;
--- Remove the oxygen free copper predetermined Metallographic detection.
