Brass (Copper-Zinc): Good electrical conductivity and moderate strength, used for electrical components but has lower corrosion resistance. Bronze (Copper-Tin): High strength and good corrosion resistance, used for bearings and marine hardware but has lower conductivity. Copper-Nickel (Cu-Ni): Excellent corrosion resistance, high tensile strength and conductivity, commonly used in demanding energy applications.
Good thermal conductivity and corrosion resistance from the nickel content. Copper provides excellent electrical conductivity. Can be found as sheet, strip, rod, tube, and bar stock for fabricating energy components.

FAQ
The choice of alloy depends on the specific requirements of the application, including electrical conductivity, heat transfer, corrosion resistance, strength, and cost. Each alloy has unique properties and tradeoffs that must be considered to ensure the best performance and efficiency.
To ensure materials meet specs, suppliers should provide: Mill Test Certificate/Material Test Report, EN 10204 Type 3.1 Certificate, ISO 9001:2015 Certification, Heat Number/Code, Material Grade and Specification, 3rd-Party Inspection Reports, and Detailed Quality Test Certificates.
Typical forms include sheet metal (0.5-6mm thick), plate (>6mm), bar, and tube, each with specific tolerances. Optimal form/size depends on material properties, application requirements (load, environment, cost), and design considerations (geometry, structure, aesthetics).
Key properties: tensile strength, yield strength, elongation, hardness, ductility, toughness. Specify and verify by checking material specs, ASTM standards, certifications/reports, and supplier documentation to ensure materials meet requirements for the application.
Critical properties: thermal conductivity (W/m·K), electrical resistivity (Ω·m), temperature coefficient of resistance (Ω·m/K). Measured using techniques like 4-probe, van der Pauw, steady-state, or transient plane source methods. Reported in supplier datasheets at room temp and application-specific temps.
