Copper wire:
1. HIGH CONDUCTIVITY: Copper is an excellent conductive material with a high electrical conductivity. This means that copper wire is able to transmit current efficiently and create less resistance, allowing heating coils to efficiently convert electrical energy into heat.
2. High Temperature Resistance: Copper wire has good resistance to high temperatures and is able to operate for long periods of time in high temperature environments without losing performance. This makes copper wire suitable for applications requiring high temperature heating, such as industrial heating and smelting processes.
3. Mechanical Strength: Copper wire has high mechanical strength and corrosion resistance, and is able to withstand high tensions and stresses. This makes copper wire easier to handle and connect during the manufacturing and installation of heating coils.


Aluminum wire:
1. Lightweight: Compared to copper wire, aluminum wire has a lower specific gravity and is therefore lighter. This makes aluminum wire a preferred choice in weight-sensitive applications such as heating coils in the aerospace and automotive industries.
2. Good electrical conductivity: Although aluminum has a lower electrical conductivity than copper, aluminum wire still provides adequate electrical conductivity, especially in applications with lower current requirements. Aluminum wire can also be used to reduce resistance by increasing the diameter to meet specific current transfer requirements.
3. Oxidation Resistance: Aluminum has good resistance to oxidation and corrosion. This is especially important in high-temperature environments, where high temperatures and oxygen contact can cause the metal to oxidize. As a result, aluminum wire has an advantage in heating coils that need to operate for long periods of time in oxidizing environments.

The choice of copper or aluminum wire depends on specific application needs and considerations such as budget, current requirements, heating temperature, coil size and mechanical requirements. In making your choice, you should refer to the relevant engineering specifications and recommendations, and consult with a specialist heating coil manufacturer or supplier for further advice and evaluation. They can provide the best advice and solutions for your specific needs.
