What grades of brass do you know?

1, H62 ordinary brass: has good mechanical properties, good plasticity in hot state, plastic can also be cold state, 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. Used for all kinds of deep drawing and bending parts, such as pins, rivets, washers, nuts, conduits, barometer springs, screens, radiator parts, etc.

2, H65 ordinary brass: the performance is between H68 and H62, the price is cheaper than H68, but also has higher strength and plasticity, can withstand cold and hot pressure processing well, there is a tendency to corrosion rupture. Used for hardware, daily necessities, small springs, screws, rivets and mechanical parts.

3, H68 ordinary brass: has very good plasticity (is the best in brass) and high strength, good cutting performance, easy to weld, general corrosion is not stable, but easy to crack. It is the most widely used variety of common brass. Used for complex cold and deep drawing parts, such as radiator shell, conduit, bellows, cartridge, gasket, detonator, etc.

4, H70 common brass: has very good plasticity (is the best in brass) and high strength, good cutting performance, easy to weld, general corrosion is not stable, but easy to crack. Used for complex cold and deep drawing parts, such as radiator shell, conduit, bellows, cartridge, gasket, detonator, etc.

5) H75 common brass: has quite good mechanical properties, process properties and corrosion resistance. Can be well processed under hot and cold pressure. Between H80 and H70 in terms of performance and economy. For low load corrosion resistant springs.

6, H80 common brass: performance and H85 similar, but high strength, plasticity is also good, in the atmosphere, fresh water and sea water has a high corrosion resistance. Used for paper mesh, thin wall pipe, corrugated pipe and building supplies.

7, H85 common brass: has 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.

8, H90 common brass: performance and H96 similar, but the strength is slightly higher than H96, can be gold-plated extrusion of enamel. Used for water supply and drainage pipes, MEDALS, artwork, tank bands and bimetal sheets.

9, H96 common brass: strength is higher than copper (but in ordinary brass, she is the lowest), good thermal and electrical conductivity, high corrosion resistance in the atmosphere and but, and good plasticity, easy to cold and hot pressure processing, easy to weld, forge and tin plating, no stress corrosion rupture tendency. It is used as conduit, condensing tube, radiator tube, radiator fin, automobile water tank belt and conductive parts in general mechanical manufacturing.

10, HA177-2 aluminum brass: is a typical aluminum brass, has high strength and hardness, good plasticity, can be processed under hot and cold pressure, seawater and salt water has good corrosion resistance, and impact corrosion resistance, but there is dezincification and corrosion rupture tendency. Used as condensing tubes and other corrosion-resistant parts in ships and coastal thermal power plants.

11, HA177-2A aluminum brass: performance, composition and HA177-2 similar, due to the addition of a small amount of arsenic, antimony, improve the corrosion resistance to seawater, and due to the addition of a small amount of beryllium, mechanical properties are also improved, the use of HA177-2.

12, HMn58-2 manganese brass: in seawater and superheated steam, chloride has high corrosion resistance, but has a tendency to corrosion rupture; Good mechanical properties, low thermal conductivity, easy to carry out pressure processing in hot state, cold state pressure processing is acceptable, is a widely used brass variety. Important parts for working under corrosive conditions and industrial parts with low current.

13, HPb59-1 lead brass: It is a widely used lead brass, it is characterized by good machinability, good mechanical properties, can withstand cold, hot pressure processing, easy brazing and welding, general corrosion has good stability, but there is a tendency to corrosion rupture, suitable for hot stamping and cutting processing of various structural parts, such as screws, washers, gaskets, bushings, nuts, nozzles and so on.

14, HSn62-1 tin brass: in seawater has high corrosion resistance, has good mechanical properties, cold processing when cold brittle, only suitable for hot pressing processing, good machinability, easy welding and brazing, but there is a tendency of corrosion rupture (seasonal crack). Used as Marine parts or other parts in contact with seawater or gasoline.

15, HSn70-1 tin brass: is a typical tin brass, in the atmosphere, steam, oil and seawater oil high corrosion resistance, and has good mechanical properties, machinability is acceptable, easy welding and brazing, in the cold, hot state of pressure processing is good, there is corrosion rupture (seasonal crack) tendency. Used for corrosion resistant parts (such as condensing pipes) on Marine vessels, conduits in contact with seawater, steam and oil, thermal equipment parts.
