Impurities: 1 (%) Hardness :105-175 (HRB) copper content :57.5-60 .5 (%) Name: Pure Brass Origin: Zhejiang Trademark: H59 H59 brass for the cheapest price, strength, high hardness and plasticity is good, but in the hot state still well withstand pressure processing, corrosion resistance in general, other properties and H62 similar. Mechanical properties of brass, zinc content, mechanical properties are not the same, Figure 7 is a brass mechanical properties vary with the zinc content of the 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. H62 (ie forty-six brass) at room temperature β phase much harder than α, which can be used to bear a greater load of parts. α + β two-phase brass at above 600 ℃ thermal processing. α + β brass two-phase microstructure: α solid solution for the bright white, β is the CuZn-based ordered solid solution. ● Purpose: ordinary brass extremely versatile, such as water tanks with water supply and drainage, medals, bellows, serpentine tube condenser, shell and various forms of complex impulse products, hardware, etc. With zinc content increases from H63 to H59, they can well withstand thermal processing, and more for a variety of mechanical and electrical 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 Impurity: 1 ● Mechanical Properties: Tensile strength: (σb / MPa) 294 Elongation: (δ10 /%) ≥ 10 Vickers hardness: (HV) 105-175 (thickness ≥ 0.3) Note: the thickness 0.3-10
