What is the difference between aluminum coil and copper coil?

Aluminum coil and copper coil are both metal coils used in various industries, but they have distinct properties. Aluminum coil is lighter, more corrosion-resistant, and less expensive than copper coil. It is often used in applications where weight and cost are concerns, such as in construction and electrical wiring. Copper coil, on the other hand, has superior electrical conductivity and is more ductile, making it ideal for electrical applications where high conductivity is required, such as in power transmission cables and wiring for electronics. Copper is also used in plumbing due to its resistance to corrosion. In summary, the choice between aluminum and copper coil depends on the specific requirements of the application, including factors like conductivity, weight, cost, and resistance to corrosion.
