| Conductivity | Excellent | Lower than copper |
| Corrosion Resistance | Very Good | Prone to corrosion, especially in the presence of moisture |
| Ductility | Excellent | Lower than copper, more prone to breakage during bending |
| Heat Resistance | Excellent | Expands and contracts more with temperature changes |
| Connection Stability | Very Good | Prone to loosening at connections due to expansion/contraction |
| Safety | Generally considered safer | Requires special installation techniques and anti-oxidant compounds |
| Cost | Generally more expensive initially | Generally less expensive initially |
As you can see, while aluminum may offer a lower initial cost, it also presents several challenges that can impact wiring safety and long-term reliability. Aluminum's higher expansion and contraction rate with temperature changes can lead to loose connections over time, increasing the risk of arcing and electrical fires. Furthermore, aluminum's susceptibility to corrosion can further compromise its conductivity and safety.
If your home has aluminum wiring, it's crucial to have it inspected by a qualified electrician. They may recommend retrofitting the connections with copper pigtails and using special anti-oxidant compounds to mitigate the risks associated with aluminum.
Key Factors in Choosing Safe Conductors
