C28000/H60/H62 has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy fiber welding and welding, corrosion resistance, but easy to produce corrosion cracking, in addition to cheap price, is a common brass variety widely used. Can do all kinds of deep drawing and bending manufacturing force parts, such as pins, rivets, washers, nuts, pipes, barometer springs, screens, radiator parts, etc.
Has a very good plasticity (brass is the best) and high strength, can be good machining performance, easy welding, the general corrosion is very stable, but easy to produce corrosion cracking.
C23000/H85 copper alloy is an irreplaceable strategic metal material in aviation, aerospace, military, electronics, nuclear energy and other fields. The copper alloy with good processing performance and excellent performance has the advantages of good thermal conductivity, electrical conductivity, heat resistance, wear resistance, corrosion resistance, non-magnetism, small elastic hysteresis, and no sparks during impact. It is widely used in national defense, instrumentation, Instruments, computers, automobiles, home appliances and other industries.
C12200/TP2 has good welding performance and cold bending performance. Generally, it has no "hydrogen disease" tendency. It can be processed and used in reducing atmosphere, but it is not suitable for processing and using in oxidizing atmosphere. It is mainly applied in pipe, and can also be supplied in plate, belt or bar and line. Used as gasoline or gas transmission pipe, drain pipe, condenser pipe, mine pipe, condenser, evaporator, heat exchanger, train parts.
C12000 welding performance and cold bending performance is good, generally no "hydrogen disease" tendency, can be processed in the reducing atmosphere, use, but not in the oxidizing atmosphere of processing, use, mainly to pipe applications, can also be plate, belt or bar, line supply. Used as gasoline or gas transmission pipe, drain pipe, condenser pipe, mine pipe, condenser, evaporator, heat exchanger, train parts.
C12000/TP1 has good welding performance and cold bending performance, generally has no "hydrogen disease" tendency, can be processed and used in reducing atmosphere, but should not be processed and used in oxidizing atmosphere, mainly for pipe application, but also for plate, belt or bar and line supply. Used as gasoline or gas transmission pipe, drain pipe, condenser pipe, mine pipe, condenser, evaporator, heat exchanger, train parts.
C10200/TU1 is a high-purity, oxygen-free, phosphorus-free deoxidized copper in vacuum without evaporating elements. It has high electrical and thermal conductivity, good welding performance and excellent welding performance attributes. It has excellent hot and cold forming properties, and has good compression resistance and corrosion resistance, especially in the atmosphere, due to the good adhesion of the oxide layer.
C11000/T2 is pure copper, also known as copper, copper has good electrical conductivity, thermal conductivity, corrosion resistance and processing performance, can be welded and brazed. Contains less impurities to reduce electrical conductivity, thermal conductivity, trace oxygen has little effect on electrical conductivity, thermal conductivity and processing properties, but it is easy to cause "hydrogen disease". It is not suitable for processing (annealing, welding, etc.) and use in a reducing atmosphere at high temperature (such as> 370 ℃).

C27000 brass has good mechanical properties and high strength and plasticity, can well withstand cold and hot pressure processing, and has a tendency to corrode and crack. Widely used in aerospace, electric power, petrochemical, shipbuilding, machinery, electronics, environmental protection and other industries.
C27400/H63 has good mechanical properties, plasticity can also be cold, good machinability, easy fiber welding and welding, corrosion resistance, but easy to produce corrosion cracking, in addition to cheap, is the most widely used a common brass varieties. Various deep-drawn and bent parts, such as pins. Rivets. Gaskets. Nuts. Catheters. barometer spring. A screen. Radiator parts, etc.
C26200/H68 has very good plasticity (brass is the best) and high strength, good machinability, easy welding, very stable for general corrosion, but easy to produce corrosion cracking in ammonia atmosphere. H68 is one of the most widely used varieties in brass. H68A with trace amounts of arsenic, can prevent brass dezincification, and improve the corrosion resistance of brass.
