 Chinese Brass brand features 1, H59 common brass; the price is cheaper, the strength and hardness are high, but it can withstand pressure processing well under heat treatment, with good corrosion resistance. Other properties are similar to H62. For general machine parts, welding parts, hot stamping and hot stamping parts.





2. H62 common brass has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy soldering and welding, corrosion resistance, and low price. It is a common brass used frequently. Used for all kinds of deep drawing and bending parts, such as pins, rivets, washers, nuts, conduits, barometer springs, screens, radiator parts, etc.




3. H63 national standard brass, suitable for cold pressure processing, Jinguang brass is suitable for welding and brazing. Easy polishing is the main alloy for wire drawing, binding and bending. Round roller for screw and pickling, etc.




4. H65 national standard brass, with properties between H68 and H62, is cheaper than H68, has higher strength and plasticity, and can withstand cold and hot pressure processing well. For hardware, daily necessities, small springs, screws, rivets and mechanical parts.



5. H68 national standard brass, with excellent plasticity (the better one among brass) and high strength, good cutting performance, easy welding, non bearing stability for general corrosion, but easy to crack. It is a kind of common brass widely used. For complex cold stamping and deep stamping parts, such as radiator shell, conduit, bellows, shell, gasket, etc.




6. H70 neutral brass: it has excellent plasticity (the best one among brass) and high strength. It has good cutting performance and is easy to weld. It is not stable for general corrosion. It is used for complex cold stamping parts and deep stamping parts, such as radiator shell, conduit, bellows, shell and gasket.




7. H75 neutral brass has good mechanical properties, technological properties and corrosion resistance. It can be processed under hot and cold conditions. It is between H80 and H70 in performance and economy. For low load corrosion resistant spring.




8. The properties of H80 high-precision brass are similar to those of h85, but its strength is higher, its plasticity is better, and its corrosion resistance is higher in atmosphere, fresh water and sea water. It is used for papermaking net, thin wall pipe, corrugated pipe and house building supplies.




9. H85 high-precision brass, with high strength and good plasticity, can well withstand cold and hot pressure processing, welding and corrosion resistance. Used for condensing and cooling pipes, siphons, serpentine pipes, cooling equipment parts.



10. H90 high-precision brass, similar to H96 in performance but slightly higher in strength, can be plated with metal extrusion enamel. For water supply and drainage pipes, medals, works of art, water tank belt and bimetal sheet.





11. H96 brass has higher strength than red copper (but in common brass, it is lower), good conductivity and thermal conductivity, high corrosion resistance in atmosphere and fresh water, good plasticity, easy to cool
