The HERO BRONZE Series
Our special high-strength brass has great wear resistance. We produce Hero Bronze, our special high-strength brass series, using state-of-the-art equipment from start to finish. Hero Bronze has a long track record, and is particularly well known for its many years of use in the manufacture of hydraulic piston material. The Hero Bronze series allows you to select from a family of extremely high quality alloys that are exceptionally machinable, caulkable and forgeable.

Features and applications
| Type | Applications | Features |
|---|---|---|
| Hydraulic parts | Pump shoes | HB-71 copper alloy provides high wear resistance as well as excellent machinability and caulking. High wear resistance is developed by dispersing and precipitating intermetallic compounds and fine lead particles throughout the basic crystalline structure of α+β brass. Various production processes – hot extrusion, cold drawing and heat treatment – make the crystal grains finer. This results in material with the desired strength, that is especially machinable, caulkable, forgeable and drawable. |
| Cylinder blocks | ||
| Piston shoes | ||
| Rolling machine parts | Slipper bearings | With HB-91 copper alloy, you get high strength and wear resistance as well. The great strength and wear resistance of HB-91 copper alloy is produced by adding several elements to α+β brass. Its special features are great durability and strength against fatigue. It is suitable for materials that encounter friction and sliding under heavy loads, and it also sustains high impacts. |
| Liners | ||
| Thrust bearings | ||
| Guide bushings | ||
| Car parts | Synchronizer rings | HB-92 copper alloy has great wear resistance, strength and caulking. HB-92 is a copper alloy that was recently developed by modifying HB-91. It has improved caulking , due to slightly increased softness, in addition to improved strength and wear resistance. |
