Physical Properties
Heat Treatment Process
Solution Treatment: Heat the copper alloy evenly to 780~800°C until the whole section reaches temperature. Then quench rapidly in water.
Annealing: Heat the copper alloy to 620~660°C, hold it well at temperature, and then let it cool slowly inside the furnace.
Aging: Aging temperature 310~330°C, hold for 2–3 hours.
Application Fields
Plastic mold inserts, mold cores, hot runner components, electrical springs, connectors, contact parts, bellville washers, instrument bearings, aerospace bushings.
