0.5-1.5 | 0.05 -0.25 | Remainder |
Mechanical Properties | Tensile Strength: ~ 450 – 600 MPa (depending on temper and heat treatment) Yield Strength: ~ 350 – 500 MPa Hardness: ~ 120 – 160 HV (up to 180 HV after aging treatment) Excellent Wear Resistance: Retains hardness and surface integrity in high-load and sliding conditions Good Fatigue Resistance: Reliable under repeated stress cycles |
Electrical and Thermal Conductivity | Electrical Conductivity: ~ 80 – 90% IACS, significantly higher than most high-strength copper alloys Thermal Conductivity: High, ensuring efficient heat dissipation in demanding environments Conductivity Retention at Temperature: Maintains good conductivity even after extended exposure to elevated temperatures |
Corrosion and Oxidation Resistance | Resistant to softening and oxidation at elevated service temperatures Better corrosion resistance than many other high-strength copper alloys Suitable for use in industrial, marine, and aerospace environments |
High-Temperature Stability | C18150 is notable for its ability to maintain strength and hardness at elevated temperatures (up to ~500 °C). This makes it especially suitable for resistance welding electrodes and thermal transfer components that are exposed to cyclic heating. |
Processing and Workability | Can be hot- and cold-worked before final aging treatment Readily machinable compared to beryllium-containing alloys Suitable for joining processes such as brazing and welding, though machining is often preferred for critical components Can be surface-treated (e.g., plating) for enhanced service life |
Resistance Welding | Widely used in resistance spot welding (RSW) electrodes, seam welding wheels, and projection welding tips Provides longer electrode life compared to pure copper due to its hardness and wear resistance Maintains high conductivity, which ensures efficient current transfer and reduces heat generation at contact points |
Aerospace Industry | Used in components exposed to high thermal and mechanical stresses, such as: Rocket engine parts Electrical connectors in spacecraft Components in turbines requiring both conductivity and high-temperature stability |
Automotive Manufacturing | Welding electrodes and holders for automotive body assembly lines Components in electric vehicles (EVs) requiring efficient heat dissipation and electrical performance High-performance connectors for hybrid systems |
Electrical and Power Generation | Electrical contacts and terminals where low resistance and mechanical durability are required Components in high-voltage switchgear Busbars and connectors in power plants and renewable energy systems |
Mold and Die Applications | Frequently used in plastic injection molds, especially where rapid heat removal is needed for cycle efficiency Cooling inserts for die casting and extrusion molds Balances wear resistance with excellent thermal conductivity for long tool life |
Industrial Equipment | Non-magnetic, wear-resistant components in industrial machinery Heat exchangers and cooling plates in heavy-duty equipment Bearings and bushings subjected to combined mechanical and thermal stresses |
Additive Manufacturing & Advanced Manufacturing | Used as a base material in 3D printing (additive manufacturing) of copper alloys, especially for aerospace and defense components that demand high conductivity and strength. Also applied in conformal cooling channels within molds, where rapid heat removal is critical for improving production efficiency. |
