Commercially important metals are those that play a vital role in industry due to their availability, performance characteristics, and economic value. These include widely used structural metals like steel and aluminum, as well as specialized metals such as copper, titanium, and nickel alloys. Their properties—such as strength-to-weight ratio, corrosion resistance, electrical conductivity, and workability—make them essential across sectors including construction, transportation, electronics, and energy. Understanding these metals and their common uses helps engineers and manufacturers choose the most effective materials for a given application, balancing performance, cost, and manufacturability.
