Aluminum Bronze – Materials and norms

This aluminum bronze alloy has high strength and wear resistance and is therefore suitable for cog and worm gears, bushings or bearings.

This aluminum bronze alloy has been especially developed to be used in forming rolls and bending and wiping blocks. It exhibits outstanding hardness, great compressive strength and good friction properties at the same time.

AMPCO83 is an alloy of copper, beryllium, cobalt and nickel. It can be used in electrical and welding components where good electrical or thermal conductivity and solid mechanical properties are required.

CuAl9 (CC330G) exhibits high tensile strength and good elongation properties, making it suitable for applications requiring durability and flexibility This alloy is commonly used in the manufacturing of ingots and castings for various industrial applications, including structural components and machinery parts. Additionally, CuAl9 (CC330G) is favored for its good thermal and electrical conductivity. Specific applications of CuAl9 (CC330G) include valve bodies, propeller hubs, worm gears, propeller blades, and wear plates.

CuAl9Fe3 is comparable to CuAl10Fe2 (CC331G). This alloy exhibits high strength and ductility as well as high wear-, corrosion- and erosion resistance. It is used for heavy duty components, e.g. in gears (pinions), bushings, grommets, sleeves, spacers etc. 

CuAl9Mn2 is a durable aluminum bronze which is used in production of gears, bushings or plastic injection

CuAl10Fe2 (CC331G) is an extremely hard and tough bronze that can withstand not only static and dynamic loads, but also seawater, corrosion and erosion. It works well even at higher temperatures. It is used in transmissions (shafts, worm and gear wheels, rims, bearings), but also for sliding elements, components of control systems in hydraulics (guide bushes), screws, bolts, nuts, valve seats and forgings.

CuAl10Fe3Mn2 (CW306G) is suitable for the construction of engine components that must withstand dynamic loads, vibrations or shocks. It is used in transmissions (shafts, worm and gear wheels, rims, bearings), but also for sliding elements, components of control systems in hydraulics (guide bushes), screws, bolts, nuts, valve seats and forgings.

CuAl10Fe4Ni4 is an older Czech designation for CuAl10Ni5Fe4 (CW307G). It is one of the most popular aluminum bronzes. This material has high strength (even at temperatures around 400°C), resistance to erosion, cavitation, abrasion, corrosion (even in seawater) and good fatigue life. However, the machinability is quite poor. Sliding properties are good if enough lubrication is provided. It is used in components exposed to high mechanical or chemical stress such as bearing bushes and pressure nuts, as well as on steam fittings, slip rings, cog and worm gears, mechanical joints, bushings, condenser plates and heat exchangers, etc. CuAl10Ni5Fe4 is similar to CuAl10Fe5Ni5.

CuAl10Fe5Ni5 (CC333G) is similar to CuAl10Ni5Fe4 and CuAl10Ni. It is one of the most popular aluminum bronzes. This material has high strength, resistance to erosion, cavitation, abrasion, corrosion (even in seawater) and good fatigue life. However, the machinability is quite poor. Sliding properties are good if enough lubrication is provided. It is used in components exposed to high mechanical or chemical stress (shocks, friction, corrosion environment at higher temperatures) such as bearing bushes and pressure nuts, as well as steam fittings, slip rings, cog and worm gears, mechanical joints, bushings, etc. 

CuAl10Ni is the German designation for CuAl10Fe5Ni5 (CC333G). It is one of the most popular aluminum bronzes. This material has high strength, resistance to erosion, cavitation, abrasion, corrosion (even in seawater) and good fatigue life. However, machinability is more difficult. Sliding properties are good as long as sufficient lubrication is ensured. However, the machinability is quite poor. Sliding properties are good if enough lubrication is provided. It is used in components exposed to high mechanical or chemical stress (shocks, friction, corrosion environment at higher temperatures) such as bearing bushes and pressure nuts, as well as steam fittings, slip rings, cog and worm gears, mechanical joints, bushings, etc. CuAl10Ni is similar to CuAl10Ni5Fe4.

CuAl10Ni5Fe4 (CW307G) is one of the most popular aluminum bronzes. This material has high strength (even at temperatures around 400° C), resistance to erosion, cavitation, abrasion, corrosion (even in seawater) and good fatigue life. However, the machinability is quite poor. Sliding properties are good if enough lubrication is provided. It is used in components exposed to high mechanical or chemical stress such as bearing bushes and pressure nuts, as well as steam fittings, slip rings, cog and worm gears, mechanical joints, bushings, condenser blades, heat exchangers, etc. CuAl10Ni5Fe4 is similar to CuAl10Fe5Ni5 and CuAl10Ni.

CuAl11Fe6Ni6 (CW308G, CC334G) has almost the same properties as CuAl10x alloys. It has even greater strength and resistance to cavitation and wear, so it can be used in extremely heavy duty bearings, worm gears, valves, cover plates, dies or high-pressure steam fittings. CuAl11Fe6Ni is also used in production of ship components.

This material has high strength, resistance to erosion, cavitation, abrasion, corrosion (even in seawater) and good fatigue life. It is used on valves (bushings, seats, pistons), pumps, bolts, worm gears, sliding plates, welding jaws, bearings, rings, gears and generally on components that are exposed to saline water.

Hovadur B20 is a special aluminum bronze alloy that combines high tensile strength with resistance to wear, corrosion and cavitation. Slower wear of tools during machining is an advantage. It is used for heavy duty bearings, guide bushes, sliding elements, mold cores, etc.
