Product code Features
HD-10S
(Soft type)
Due to the high structual concentration and large surface area, this alloy to excel significantly in hardness, strength, wear resistance and corrotion resistance compared with other copper alloys. It also has good workability.
HD-10H
(Hard type)
The composition is the same as HD-10S, but by changing the percentages of each component a stronger alloy with better wear resistance, corrosion resistance is achieved. It also has excellent spring properties.
HD-11SP This alloy has strength equivalent to 42 alloy of iron and nickel and has excellent heat resistance, thermal radiation and good workability for cold forging.
HD-12S
(Soft type)
An age hardened copper alloy, with good heat resistance and high electric conductivity. It is a Cu-Ti-Fe titanium alloy with good workability in bending, drawing and spring etc.
HD-12H
(Hard type)
Small modifications were made to the composition components of HD-12S to achieve a high strength, highly electric conductive alloy with better hardness and strength.
HD-13TE This alloy has high thermal conductivity and electric conductivity, with exellent resistance to thermal stress relief; It also has good heat resistance due to both the Peltier Effect and Seebeck Effect.
