Aluminium vs. Copper: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 14, 2024
Aluminium is a lightweight, silvery metal with high corrosion resistance. Copper is a reddish-brown metal known for its high thermal and electrical conductivity.

Key Differences

Aluminium is a lightweight metal, making it ideal for applications where weight is a concern, such as in aerospace. In contrast, copper is heavier but excels in electrical conductivity, making it a primary choice for electrical wiring.

Aluminium is notable for its ability to form strong lightweight alloys with other metals, broadening its range of applications. Copper is less frequently alloyed, as it's often valued more for its pure form's properties, especially in electrical and thermal applications.
