H68 GB brass wire, all soft annealed copper wire, all soft brass wire, copper wire drawing

Brass is an alloy of 70, with high strength, good plasticity, can well withstand cold, hot pressure processing, welding and corrosion resistance are also used for condensing and cooling pipes, siphons, serpentine cooling equipment parts. H85 brass electrical conductivity, thermal conductivity, and has high corrosion resistance in the atmosphere and fresh water, and there is good plasticity, H85 easy to cold and hot pressure processing, easy welding, forging, and tin, no stress corrosion cracking tendency. Chemical composition (%): Cu: 84-86 Fe: ≤0.5 Pb: ≤0.03 Ni: ≤0.3 Zn: the sum of the margin of impurities: ≤0.1 Mechanical Properties: Tensile strength σb (MPa): ≥315 Elongation δ10 ( %): ≥25 Elongation δ5 (%): ≥30 Note: The vertical bars at room temperature tensile mechanical properties of the sample size: the diameter or on the side away from> 12 to 40 Heat Specifications: thermal processing temperature of 750 ~ 830 ℃; annealing temperature 520 ~ 650 ℃; alloys to eliminate the stress of low temperature annealing temperature of 260 ~ 270 ℃ ordinary brass from copper and zinc. When the zinc content of less than 39% of zinc can be dissolved to form a single-phase copper a, known as single-phase brass, plastic, suitable for hot and cold pressure processing. When zinc is greater than 39% when there is a single-phase as well as in b copper and zinc-based solid solution, called duplex brass, b and the tensile strength of the plastic small rise, if only for thermal pressure processing continues to increase zinc The mass fraction, the tensile strength decreased, no use value code with "H + digital" represents, H is brass, numbers indicate the mass fraction of copper. H68 expressed as the amount of 68% copper, 32% zinc brass, cast brass in front codenamed "Z" word, such as Zcuzn38 expressed ZH62 zinc content of 38%, the balance being copper casting brass. H90, H80 single-phase, golden yellow, it has a total gold Moreover, he called plating, decorations, medals and so on. H68, H59 brass are biphasic, widely used in structural parts on appliances, such as bolts, nuts, washers, springs, etc. In general, cold deformation with single-phase brass hot deformation processing phase brass.
