The properties of copper-clad aluminium wire include:
- Less expensive than a pure copper wire
- Lighter than pure copper
- Higher electrical conductivity than pure aluminium
- Higher strength than aluminium
- Better solderability than aluminium, due to the lack of the oxide layer which prevents solder adhesion when soldering bare aluminium
- Electrical connections are typically more reliable than pure aluminium
- Typically produced as a 10% or 15% by copper volume product
