GB/T 32286.1-2015 English PDF (GBT32286.1-2015)

This part of GB/T 32286 specifies the classification, order content, dimensions, appearance, technical requirements, test methods, inspection rules, packaging, marking and quality certification for nickel-iron soft magnetic alloy materials. This Part applies to cold-rolled strips, cold-drawn wires, cold-drawn (rolled) pipes, hot-rolled (forged) rods and flat bars of higher permeability and higher saturation magnetic induction intensity nickel-iron alloys 1J46, 1J50, 1J54 and high permeability nickel-iron alloys 1J76, 1J77, 1J79, 1J80, 1J85, 1J86; cold-rolled sheets of high permeability nickel-iron alloys 1J79 and 1J85; cold-rolled strips of nickel-iron rectangular magnetic alloys 1J34, 1J51, 1J52, 1J65, 1J67, 1J83, 1J403; cold-rolled strips of magnetic temperature compensation nickel-iron alloys 1J30, 1J31, 1J32, 1J33, 1J38; and cold-rolled strips of permanent permeability nickel-iron alloy 1J66. This Part does not apply to high hardness, high resistance and high permeability nickel-iron alloy materials, corrosion-resistant nickel-iron alloys and nickel-iron alloy materials for magnetic heads.
