Titanium alloys are light, which makes them very useful. They weigh only 4.51 g/cm³, which is about half the weight of steel. This low weight gives them a high strength-to-weight ratio. This means they are great for jobs where saving weight is important. Engineers can make thinner frames and structures without losing strength. The table below shows how titanium compares to other materials:
Material | Weight Comparison | Strength-to-Weight Ratio |
|---|---|---|
Titanium | Half the weight of monel | Highest among metallic elements |
Monel | Standard weight | Lower than titanium |
Aluminum | 60% heavier than titanium | Twice as strong as aluminum |
Titanium alloys help create new designs that focus on performance while being light.
