Product DescriptionProduct DescriptionC17500(CuCo2Be) COPPER COBALT BERYLLIUM INTRODUCTION:C17500, also referred to as Alloy 3 or UNS C17500, is a high-performance beryllium copper alloy that combines moderate strength with excellent electrical and thermal conductivity. It belongs to the family of precipitation-hardened copper alloys containing small amounts of beryllium and cobalt. C17500 is often considered a "conductivity grade" beryllium copper, designed to balance conductivity, strength, and durability, making it suitable for demanding electrical, electronic, and mechanical applications.CHEMICAL COMPOSITIONS(%)BeCoAlSiCu0.4-0.72.4-2.70.2(Max)0.2(Max)RemainderKEY CHARACTERISTICSMechanical PropertiesTensile Strength: ~ 620 – 930 MPa (90 – 135 ksi) after heat treatmentHardness: ~ 150 – 300 HV (depending on temper)Good wear resistanceRetains strength and spring properties over timeElectrical and Thermal ConductivityElectrical Conductivity: ~ 45 – 60% IACSThermal Conductivity: High, suitable for heat dissipation applicationsMaintains conductivity better than higher-strength alloys such as C17200Corrosion and Oxidation ResistanceExcellent resistance to corrosion in marine and industrial environmentsOxidation resistance at elevated temperaturesProcessing and WorkabilityGood machinability compared to harder beryllium copper gradesCan be cold-worked prior to age-hardeningCompatible with plating and surface finishingFatigue and Stress Relaxation ResistanceC17500 exhibits excellent fatigue resistance and maintains its mechanical properties under cyclic loading conditions. It also shows low stress relaxation, meaning it retains its spring force and contact pressure over long service periods, even at elevated temperatures. This makes it ideal for use in springs, connectors, and contact components that must deliver reliable performance over time.TYPICAL APPLICATIONSElectrical and Electronic applicationElectrical connectors and terminalsRelay and switch componentsContact springs and bushingsCurrent-carrying parts requiring both strength and conductivityResistance Welding and ElectrodesElectrode holdersWelding electrodes where moderate strength and higher conductivity are preferred over maximum hardnessAerospace and DefenseAvionics componentsAircraft electrical connectors and housingsHeat-resistant parts subjected to mechanical stressThermal ManagementHeat sinksCooling components in electronics and power systemsAutomotive IndustryHigh-performance ignition and electronic systemsElectric vehicle connectorsComponents in hybrid/electric drivetrains requiring high conductivity and durabilityOil & Gas IndustryDownhole drilling tools and non-sparking componentsEquipment for explosive or flammable environments where non-magnetic and spark-resistant properties are criticalMedical DevicesHigh-reliability electrical connectors for diagnostic equipmentPrecision instruments requiring both biocompatibility and electrical performancePRODUCT IMAGES AND FACILITIESCompany ProfileRich Base Technology Co., LimitedYour Trusted Partner in Copper Alloy Materials!Founded in 2007, Rich Base Technology Co., Limited is one of the leading manufacturers of copper alloy materials in China.
