Impurities: 1 (%) copper content :58-60 (%) Tensile strength (σb / MPa): 286 Name: pure brass size: 0.035 (mesh) Origin: Shanghai Trademark: H59 elongation (δ10 /% ): ≥ 10 Hardness :105-155 (HRB) Shanghai B Wang Industrial Co., Ltd. specializes in producing all kinds of brass strip, length is generally 4M. High hardness, good processing performance, status and stability. Common specifications such as 4000 * 10 * 3,4000 * 8 * 8, which are inventory stocking, shelf, a large quantity can be customized production. H59 is the cheapest brass, strength, high hardness and good ductility, but in the hot state still well withstand pressure processing, corrosion resistance in general, other similar properties and H62 Brass is composed of copper and zinc alloys. If only the copper, zinc composition of the brass called ordinary brass When the amount is less than 39% zinc, the zinc can be dissolved copper to form single-phase a, known as single-phase brass, plastic, suitable for hot and cold press processing. When zinc is greater than 39%, there is a single-phase and the b-copper and zinc-based solid solution, said phase brass, b increase the plasticity is small and tensile strength, heat stress is only suitable for processing, if it continues to increase the mass fraction of zinc, then drop in tensile strength, no use value, code with "H + number" indicates, H represents brass, copper numbers indicate the mass fraction. Expressed as H68 copper content of 68%, 32% zinc, brass, cast brass in the code before the "Z" words, such as ZH62, Zcuzn38 expressed zinc content of 38%, the balance being copper cast brass. H90, H80 single-phase, golden yellow, so there were termed gold, known coating, decorations, medals and so on. H68, H59 belongs phase brass, widely used in electrical appliances on the structural parts, such as bolts, nuts, washers, springs, etc.. Generally, the cold deformation process with a single-phase brass hot deformation processing phase brass. Mechanical properties of brass, zinc content, mechanical properties are not the same, the mechanical properties of brass with zinc content varies curve. For α brass, with zinc content, σb and δ are constantly increased. For the (α + β) brass, the zinc content increased about 45%, room temperature strength continues to increase. Ruozai further increase the amount of zinc, due to the alloy appeared brittle larger r (to Cu5Zn8 compounds based solid solution, the intensity drastically reduced. (Α + β) brass room temperature ductility is always with zinc reduce the increase, so more than 45% zinc zinc alloy no practical value. ● Characteristics: ordinary brass, with good mechanical properties, good thermal state plastic, plastic cold state can be, good machinability, Easy brazing and welding, corrosion resistance, but easy to produce corrosion cracking. Besides cheap, widely used a variety of ordinary brass. ● Purpose: ordinary brass extremely versatile, such as water tanks with water supply and drainage, medals, corrugated tube, serpentine tube condenser, shell and various forms of complex impulse products, hardware, etc. With the increase in zinc content from H63 to H59, they can well withstand thermal processing, used for mechanical and electrical various parts, stamping parts and musical instruments, etc.. do all kinds of deep drawing and bending of the force components, such as pins, rivets, washers, nuts, catheters, barometer spring, screen, radiator parts ● Chemical Composition: Cu :57-60 Sb: 0.01 Fe: 0.3 Pb: 0.5 P: 0.01 Zn: margin impurities: 1 ● Mechanical Properties: Tensile strength: (σb / MPa) 286 Elongation: (δ10 /% ) ≥ 10 Vickers hardness: (HV) 105-155 (thickness ≥ 3)
