Copper AlloySheet/Plate
Description (English)
H60 brass combines the high ductility of higher-copper brasses with improved strength and machinability at a more economical cost. It has good cold working characteristics, excellent polishability, and good solderability,making it suitable for a wide range of industrial and decorative applications.The alloy is non-magnetic, has good electrical and thermal conductivity,and exhibits good corrosion resistance in normal atmospheric conditions and fresh water. For marine or severe chloride environments, additional protection or higher-copper alloys are recommended.
