Friends who have learned about copper know that the difference between brass and copper is very big, the composition of copper is mainly copper, and the composition of brass has copper and zinc, suitable for cold pressure processing, suitable for welding and brazing, because the material composition of brass is a lot, many people do not know the advantages of brass material when buying, the following for everyone to share the advantages of brass material.
Brass is made of copper and zinc alloy made of objects, because of the yellow name, copper content of 56% to 68% brass, its melting point is 934 to 967 degrees. The mechanical properties and wear resistance of brass are very good, and can be used to manufacture precision instruments, ship parts, gun shells and so on. In general, the amount of precision copper parts such as auto parts, medical parts, electrical parts is more.
Advantages of brass material:
1, with high strength, good plasticity, can well withstand cold and hot pressure processing, welding and corrosion resistance are also. For condensing and cooling pipe, siphon, snake pipe, cooling equipment parts.
2, has very good plasticity and high strength, good cutting performance, easy to weld, the general corrosion is not stable, but easy to crack. It is the most widely used variety of common brass. For complex cold and deep drawing parts, such as radiator shell, conduit, bellows, shell, gasket, etc.
3, the cheapest price, high strength, hardness and poor plasticity, but in the hot state can still withstand pressure processing, corrosion resistance is general, other properties and H62 similar. Used for general machine parts, welding parts, hot stamping and hot tying parts.
4, has good mechanical properties, good plasticity in hot state, cold state plasticity can also be good machinability, easy brazing and welding, corrosion resistance, but easy to produce corrosion rupture. In addition, the price is cheap and is a common brass variety used by repeat offenders.
5, with high strength, toughness, good anti-friction, high corrosion resistance in the atmosphere and sea water, but there is a tendency to corrosion rupture, good plasticity in hot state. It is used to make structural parts that work under conditions of friction and corrosion by seawater.
