Common Brass Category:


H59 ordinary brass; the cheapest price, strength, high hardness and poor plasticity, but in the hot state can still withstand the pressure processing, corrosion resistance in general, other properties and H62 similar. For general machine parts, welding parts, hot and hot bar parts.

H62 ordinary brass; have good mechanical properties, hot plastic under the plastic, cold plastic can also be, good cutting, easy brazing and welding, corrosion, but easy to produce corrosion cracking. In addition, cheap, is the application of an ordinary breed of brass. For a variety of deep drawing and bending manufacturing of the ritual parts, such as pins, rivets, washers, nuts, ducts, barometers springs, screens, radiator parts.

H63 ordinary brass; suitable for cold under pressure processing, suitable for welding and brazing. Easy to polish, is the drawing, barning, bending and other molding to the main alloy. For the screw, pickling with the round roller.

H65 ordinary brass; performance between H68 and H62, the price is cheaper than the H68, but also a high strength and plasticity, can withstand good cold, hot pressure processing, corrosion cracking tendency. For small hardware, daily necessities, small springs, screws, rivets and mechanical parts.

H68 ordinary brass; has a very good plasticity (the best in brass) and high strength, good cutting performance, easy welding, corrosion of the general non-bearing, but easy to produce cracking. Is the most widely used in a variety of brass varieties. For the complex cold and deep pieces, such as radiator shell, catheters, bellows, shells, gaskets and so on.

H70 ordinary brass; has a very good plasticity (the best in brass) and high strength, good cutting performance, easy welding, corrosion of the general non-bearing, but easy to produce cracking. For complex cold and deep pieces, such as radiator shell, catheters, bellows, shells, gaskets.

H75 ordinary brass; have quite good mechanical properties, process performance and corrosion resistance. Can be well in the hot and cold under pressure processing. In the performance and economy living in H80, H70 between. For low load corrosion resistant springs.

H80 ordinary brass; performance and H85 similar, but the higher strength, plastic is also better in the atmosphere, fresh water and seawater have a higher corrosion resistance. For the paper network, thin-walled tube, bellows and housing construction supplies.


hpb 57-3 brass


H85 ordinary brass; with high strength, good plasticity, can withstand good cold, hot pressure processing, welding and corrosion resistance are also. For condensing and cooling tubes, siphon, serpentine, cooling equipment parts.

H90 ordinary brass; strength higher than the copper (but in ordinary brass, it is the lowest), conductive, good thermal conductivity, in the atmosphere and fresh water has a high corrosion resistance, and a good plastic, easy to cold , Hot press processing, easy welding, forging and tinning, no stress corrosion cracking tendency. Hot working temperature 850 ~ 950 ℃; annealing temperature 650 ~ 720 ℃; elimination of internal stress low temperature annealing temperature of 200 ℃.

H96 ordinary brass; H96 brass strength than copper (but in ordinary brass, it is the lowest), conductive, good thermal conductivity, in the atmosphere and fresh water has a high corrosion resistance, and a good plastic , Easy to cold, hot pressure processing, easy welding, forging and tinning, no stress corrosion cracking tendency.
