Bare Aluminum Wire FAQ
What are the advantages of using Bare Aluminum Wire over copper?
Bare Aluminum Wire offers several advantages: it's significantly lighter (about 70% lighter than equivalent copper wire), more cost-effective (typically 50-60% of copper's price), and has excellent corrosion resistance. While its conductivity is about 61% that of copper, its lighter weight and lower cost make it ideal for long-distance power transmission where weight and cost are critical factors.
How should Bare Aluminum Wire be stored and handled?
Bare Aluminum Wire should be stored in a dry, well-ventilated area away from corrosive chemicals. Keep it on wooden pallets or plastic-covered surfaces to prevent ground contact. When handling, use clean gloves to prevent contamination, and avoid bending beyond the minimum bend radius (typically 10 times the wire diameter). For large reels, use proper lifting equipment to prevent mechanical damage.
What are the temperature limitations for Bare Aluminum Wire?
The continuous operating temperature for Bare Aluminum Wire is typically rated up to 90°C (194°F), with short-term overload capability up to 150°C (302°F). The melting point of aluminum is approximately 660°C (1220°F). For high-temperature applications, specially treated aluminum alloys or different materials may be more appropriate.
Aluminum vs Copper Wire Comparison
| Property | Bare Aluminum Wire | Bare Copper Wire |
