New AMPCO HD - A material with low coefficient of friction and superior mechanical characteristics
The AMPCO Group presents the AMPCO® HD which combines high ductility with high hardness and
exceptional sliding properties.
This material is based on the Cu-Mn binary system, with the adoption of some micro alloying elements to achieve
unique properties and exceed the performance of phosphor bronze alloys, aluminum bronzes and brasses.
Unlike bronze and brass alloys, this material has a bright silver color allowing it to be easily identified among other
copper-based alloys.
Typical applications are worn parts such as bushes, rings, nuts and rulers, as well as special applications where
controlling noise and vibration is important.
Pilot quantities are now being produced at AMPCO METAL for evaluation in a variety of applications.
