Round Aluminum Conductor 2.5mm Enameled Wire is a wire with a round aluminum conductor of 2.5mm diameter, insulated by coating with an insulating varnish. This wire is typically used for low power applications or for electrical connections in specific situations.

Compared to a copper conductor of the same wire diameter, an aluminum conductor will have a higher resistance. This is due to the fact that aluminum has a lower conductivity than copper, so under the same current conditions, the aluminum conductor will have a higher resistance value. Therefore, the electrical conductivity of aluminum conductors needs to be taken into account when designing circuits to ensure that they are able to withstand the required current load without excessive heat loss.

The thermal characteristics of aluminum conductors are slightly different from those of copper conductors. The coefficient of thermal expansion of aluminum conductors is greater than that of copper, so at high temperatures, aluminum conductors may expand more. This needs to be taken into account in the design to account for the effect of thermal expansion on connections and fixings.

Aluminum conductors have a lighter weight relative to copper conductors of equivalent conductivity. This makes it possible to reduce the overall weight in some applications, especially where weight is limited, by choosing aluminum conductors.


Aluminum conductors are susceptible to oxidation. When exposed to air, an oxide layer forms on the surface of aluminum, which can affect conductivity. Therefore, when using aluminum conductors, it is necessary to take appropriate anti-corrosion measures, such as choosing specially treated enameled wire or using other protective measures.

Round aluminum conductor 2.5mm enameled wires are typically used in low power applications such as small electronic devices, light duty circuits, and some household appliances. In these applications, the light weight and relatively low cost of aluminum conductors make it a viable option.

Compared with copper conductors, aluminum conductors have better corrosion resistance, especially in some special environmental conditions, such as humid or corrosive gas environment.

Round aluminum conductor 2.5mm enameled wire applications are relatively narrow, mainly for low power and economic requirements of higher occasions. For high power applications and where higher conductivity is required, copper conductors are usually chosen.

When selecting and using round aluminum conductor 2.5mm enameled wire, it is recommended to follow the relevant electrical standards and codes to ensure that it meets safety and performance requirements. In addition, depending on the specific application requirements, calculations and evaluations of current loading and wire diameter selection may be required to ensure the reliability and performance of the electrical connection.
