How to Test and Tell if an Ethernet Cable is CCA or Pure Copper Using the Flame Test

To determine if an Ethernet cable is CCA or pure copper, perform a flame test on the wire.

Understanding CCA vs. Pure Copper Ethernet Cables

Ethernet cables can be constructed from either pure copper or copper-clad aluminum (CCA). CCA cables are less expensive but have inferior electrical properties.

Electrical Properties of CCA and Pure Copper

The electrical conductivity of pure copper is approximately 59.6 S/m, while CCA has a conductivity of around 30 S/m. This difference significantly affects performance, especially in high-speed data transmission.

Physical Characteristics of CCA and Pure Copper

Pure copper wires exhibit a bright orange color when cut, while CCA wires appear silver or dull. The weight of pure copper is also greater than that of CCA for the same gauge wire.

Conductivity and Resistance Calculations

The resistance of a wire can be calculated using the formula: R = ρ(L/A). Here, ρ is the resistivity, L is the length, and A is the cross-sectional area. For a 100-meter length of 24 AWG copper wire, resistance is approximately 0.084 ohms.
