Properties of common conductor materials. Resistivity determines how much a wire resists current flow; density affects weight; the temperature coefficient shows how resistance changes with heat.
The standard conductor for electrical wiring. Excellent conductivity, ductility, and corrosion resistance.
Lighter and cheaper than copper but requires larger gauge for equivalent ampacity. Common in utility and feeder applications.
Highest electrical conductivity of any metal. Used in specialized high-performance applications.
Excellent corrosion resistance and reliable contact properties. Used for connectors and thin plating.
High-temperature resistance and corrosion resistance. Used in thermocouples and heating elements.
Nickel-chromium alloy with very high resistance. The standard material for heating elements.
High tensile strength but poor conductivity. Used where mechanical strength matters more than electrical performance.
Copper wire coated with tin for improved corrosion resistance. Standard for marine and harsh environments.
