1. H62 ordinary brass: has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy brazing and welding, corrosion resistance, but prone to corrosion cracking. In addition, it is cheap and is a common brass variety with frequent applications. It is used for various deep extension and bending parts, such as pins, rivets, washers, nuts, conduits, pressure gauge springs, screens, radiator parts, etc.
2. H65 ordinary brass: its performance is between H68 and H62, and its price is cheaper than H68. It also has higher strength and plasticity, can withstand cold and hot pressure processing well, and has a tendency to corrosion cracking. It is used for small hardware, daily necessities, small springs, screws, rivets and mechanical parts.
3. H68 ordinary brass: has extremely good plasticity (the best among brasses) and high strength, good machinability, easy welding, and is not stable to general corrosion, but prone to cracking. It is the most widely used variety among ordinary brass. Used for complex cold stamping and deep stamping parts, such as radiator shells, conduits, bellows, shells, gaskets, detonators, etc.
4. H70 ordinary brass: has extremely good plasticity (the best among brasses) and high strength, good cutting performance, easy to weld, non-resistant to general corrosion, but prone to cracking. Used for complex cold stamping and deep stamping parts, such as radiator shells, conduits, bellows, shells, gaskets, detonators, etc.
5. H75 ordinary brass: has quite good mechanical properties, process properties and corrosion resistance. It can be well processed under hot and cold pressure. It is between H80 and H70 in performance and economy. Used for low-load corrosion-resistant springs.
6. H80 ordinary brass: has similar performance to H85, but has higher strength and better plasticity, and has higher corrosion resistance in the atmosphere, fresh water and sea water. Used for papermaking nets, thin-walled pipes, bellows and house construction supplies.
7. H85 ordinary brass: It has high strength, good plasticity, can withstand cold and hot pressure processing well, and has good welding and corrosion resistance. It is used for condensation and heat dissipation pipes, siphons, serpentine pipes, and cooling equipment parts.
8. H90 ordinary brass: The performance is similar to H96, but the strength is slightly higher than H96, and it can be plated with metal and enamel. It is used for water supply and drainage pipes, medals, artworks, water tank belts and bimetallic strips.
9. H96 ordinary brass: It has higher strength than red copper (but it is the lowest among ordinary brass), good thermal conductivity and electrical conductivity, high corrosion resistance in the atmosphere and air, and good plasticity. It is easy to process cold and hot pressure, easy to weld, forge and tin, and has no tendency to stress corrosion cracking. It is used as conduits, condensers, radiator tubes, heat sinks, automobile water tank belts and conductive parts in general machinery manufacturing.
10. HA177-2 aluminum brass: It is a typical aluminum brass with high strength and hardness, good plasticity, can be press-processed in hot and cold states, has good corrosion resistance to seawater and salt water, and is resistant to impact corrosion, but has a tendency to dezincification and corrosion cracking. It is used as condenser pipes and other corrosion-resistant parts in ships and coastal thermal power plants.
11. HA177-2A aluminum brass: The performance and composition are similar to HA177-2. Due to the addition of a small amount of arsenic and antimony, the corrosion resistance to seawater is improved. Due to the addition of a small amount of beryllium, the mechanical properties are also improved. The use is the same as HA177-2.
12. HMn58-2 manganese brass: It has high corrosion resistance in seawater, superheated steam and chlorides, but has a tendency to corrosion cracking; good mechanical properties, low thermal conductivity and electrical conductivity, easy to press-process in hot state, and acceptable pressure processing in cold state. It is a widely used brass variety. It is used for important parts working under corrosive conditions and weak current industrial parts.
13. HPb59-1 lead brass: It is a widely used lead brass. It is characterized by good machinability, good mechanical properties, ability to withstand cold and hot pressure processing, easy brazing and welding, good stability to general corrosion, but has a tendency to corrosion cracking. It is suitable for various structural parts made by hot stamping and cutting, such as screws, washers, gaskets, bushings, nuts, nozzles, etc.
14. HSn62-1 tin brass: It has high corrosion resistance in seawater, good mechanical properties, cold brittleness during cold processing, and is only suitable for hot pressing processing. It has good machinability, easy welding and brazing, but has a tendency to corrosion cracking (seasonal cracking). It is used as ship parts or other parts in contact with seawater or gasoline.
15. HSn70-1 tin brass: It is a typical tin brass, with high corrosion resistance in the atmosphere, steam, oil and seawater, and good mechanical properties. It has decent machinability, is easy to weld and braze, has good pressure processing in cold and hot states, and has a tendency to corrosion cracking (seasonal cracking). Used for corrosion-resistant parts on ocean-going vessels (such as condensers), pipes in contact with seawater, steam, and oil, and thermal equipment parts.
