Steel vs. Copper: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on November 23, 2023
Steel is a hard, strong alloy of iron with carbon and other elements, while copper is a reddish-brown, highly conductive metal used in electrical components and pipes.
Key Differences
Steel, an alloy primarily made of iron and carbon, is known for its strength and durability. Copper, however a pure element, is notable for its excellent electrical and thermal conductivity.
Steel is widely used in construction, automotive, and tool-making industries due to its strength and versatility. While, copper with its superior conductivity, is essential in electrical wiring, electronics, and plumbing.
While steel is strong, it is susceptible to corrosion unless treated or alloyed with other elements like chromium. Meanwhile, copper resists corrosion better and develops a green patina over time without losing its properties.
Steel typically has a shiny, silvery-grey appearance and can be polished to a high shine. On the other hand, copper has a distinctive reddish-brown color and is used for its aesthetic appeal in architecture and art.
Generally, steel is less expensive and more widely available than copper, which is more costly due to its electrical applications and demand in various industries.
