The application of ordinary brass: The use of ordinary brass is extremely wide, such as water tank belt, water supply and drainage pipe, medal, bellows, serpentine pipe, condensate pipe, bullet shell and various complex shapes of punching products, small hardware, etc. With the increase of zinc content from H63 to H59, they can withstand hot processing well, and are mostly used in various parts of machinery and electrical appliances, stamping parts and musical instruments.

H65 brass has sufficient mechanical properties and process performance, good cold and hot pressure performance, golden color, and is mostly used in various hardware products, lighting, piping accessories, zippers, plaques, rivets, springs, sedimentation filters Wait.

It has good plasticity and high strength, good machinability, easy welding, corrosion resistance, and good hot and cold processing performance. Generally used for various cold and deep-drawing parts, radiator shells, bellows, waveguides, doors, lamps, etc.

It can be used for various deep-drawing and bending manufacturing parts, radiator shells, ducts, bellows, bullet shells, gaskets, etc. Has good mechanical properties, good plasticity in the hot state, acceptable plasticity in the cold state, good machinability, easy fiber welding and welding, corrosion resistance, is a widely used brass variety.

the tensile strength of nickel brass alloy in the soft state is 400MPa, and the elongation is 65%. Weldability. Used to manufacture metal coins, pressure gauge tubes, paper nets, marine condensate tubes and other corrosion-resistant and pressure-resistant pipe fittings.

Lead brass is an extremely important and most widely used complex brass. It has excellent cutting performance, wear resistance and high strength. It is mainly used for various connectors, valves, Stem bearing maintenance, in which hot forged valve blanks, lock manufacturing, and watch industry are the three major markets, the low cost of lead brass is an important prerequisite for its wide application, and its alloy composition can contain a variety of alloy elements, and the content The requirements are relatively loose, which has laid the foundation for the comprehensive utilization of copper alloy raw materials.

HPb59-3 lead brass has good cold and hot workability and excellent machinability. It is usually used to make various pins, screws, gaskets, hardware, pipe fittings, bearing retainers, etc.

it is a widely used lead brass, which is characterized by good machinability, good mechanical properties, can withstand cold and hot pressure processing, easy welding, good fiber welding It has good stability to general corrosion, but has a tendency to corrode and crack. It is mainly used for air conditioning valves and hardware machinery.

Manganese brass is widely used in ships and marine engineering due to its good strength and cold and hot processing properties. It can also be used as a wear-resistant material for high-pressure pump friction pairs and automobile synchronization gear rings.

HMn58-2 manganese brass has high corrosion resistance in seawater, superheated steam and chloride, but has a tendency to corrosion cracking; good mechanical properties, low thermal conductivity, easy to be in the hot state Under the pressure processing, the cold workability is acceptable, and it is a widely used brass variety. HMn58-2 manganese brass is used for important parts working under corrosive conditions and weak current industrial parts.

HA160-0-1 aluminum brass has high ground strength, good corrosion resistance in the atmosphere, fresh water and seawater, but it is sensitive to corrosion cracking and good pressure workability in hot state. Cold plasticity is low. HA160-0-1 aluminum brass is used for structural parts requiring corrosion resistance, such as gears, worm gears, bushings, shafts, etc.

Tin brass generally has high strength and hardness, the biggest feature is the excellent resistance to seawater corrosion, so it is widely used in the marine industry and can be used to make terminals, instrument clips, spring washers, Spring bushings for vehicles, high-strength corrosion-resistant condensers for ships and thermal power plants, welding electrodes for marine structures, parts, etc.

Silicon brass has good mechanical properties, high corrosion resistance, no corrosion cracking tendency, and wear resistance is also available. It has good workability under cold and hot conditions, easy to weld and braze, and Cutting ability is good Thermal conductivity is the lowest in brass. Mainly used for ship parts, steam pipes and water pipe fittings.

Iron brass has high strength, toughness, and good friction reducing properties. It has high corrosion resistance in the atmosphere and seawater, but has a tendency to corrode and crack, and has good plasticity in the hot state. Iron brass is used to make structural parts that work under friction and corrosion by seawater.
