Foreword
This standard GB/T 1.1-2009 rules drafted.
This standard mainly with reference to the United States ASTMB49-10 "electrician copper billet" European EN1977.1998 "Copper and copper alloys - Copper
Blank "standard. The major differences are.
--- Improve the "mechanical properties, torsional properties, electrical properties' performance, anti-fracture revolutions go, not less than 30,25,20 times;
--- Conductive performance, is divided into two grades, the volume resistivity (ρ20 ° Ω · mm2/m), respectively. 0.01707,0.01724.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Ganzhou, Jiangxi Tungsten Alloy New Material Co., Ltd.
