2.5mm round enameled aluminum wire is a wire that uses a round aluminum conductor with a diameter of 2.5mm and is coated with insulating paint for insulation. This wire is typically used for electrical connections in low power applications or in specific situations.

Aluminum conductors have a higher resistance than copper conductors of the same diameter. This is because aluminum has a lower conductivity than copper, so for the same current flow, an aluminum conductor will have a higher resistance. Therefore, the electrical conductivity of aluminum conductors must be considered when designing circuits to ensure that they can carry the required current load without excessive heat loss.

The thermal characteristics of aluminum conductors are slightly different than those of copper conductors. Aluminum conductors have a higher coefficient of thermal expansion than copper, so at high temperatures, aluminum conductors can expand more. This must be taken into account during the design process to account for the effects of thermal expansion on connections and fasteners.

Aluminum conductors are lighter than copper conductors of equivalent conductivity. Therefore, in some applications, especially where weight is limited, the overall weight can be reduced by selecting aluminum conductors.



Aluminum conductors are sensitive to the effects of oxidation. When exposed to air, an oxide layer forms on the surface of aluminum, which affects electrical conductivity. Therefore, when using aluminum conductors, appropriate anti-corrosion measures should be taken, such as using specially treated enameled wires or other protective measures.

2.5mm round enameled aluminum conductors are commonly used in low power applications such as small electronics, lightweight circuits and some household appliances. The light weight and relatively low cost of aluminum conductors make them a viable option in these applications.

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

The application range of 2.5mm round enameled aluminum wire is relatively narrow, and it is mainly suitable for low-power situations and situations that focus on economy. For high power applications and where higher conductivity is required, copper conductors are often chosen.

When selecting and using 2.5mm round aluminum enameled wire, it is recommended to follow current electrical standards and codes to ensure safety and performance requirements are met. In addition, depending on the needs of the specific application, current loading and wire size selection may need to be calculated and evaluated to ensure the reliability and performance of the electrical connection.
