Lightweight metals are materials that have a low density, making them easier to handle and transport. Common examples include aluminum, magnesium, and titanium. These metals are often used in industries like aerospace and automotive because they help reduce overall weight, which can improve fuel efficiency and performance. In addition to their low weight, lightweight metals also offer good strength and corrosion resistance. This combination of properties makes them ideal for applications where both durability and weight savings are crucial. As technology advances, the use of lightweight metals continues to grow in various fields, including construction and sports equipment.
