1. Low density • Titanium has a density of about 4.5 g/cm³, which is much lower than many common metals such as iron 7.87 g/cm³ and copper 8.96 g/cm³. Therefore, titanium is lighter in the same volume.

2. High strength • The tensile strength of titanium is very high, usually between 450-900 MPa, depending on the specific alloy composition and heat treatment process. This means that titanium can withstand large loads without plastic deformation. Titanium also has a high yield strength, usually between 350-800 MPa, which allows it to hold its shape when stressed.

3. High strength-to-weight ratio • Due to titanium's low density and high strength, its strength-to-weight ratio is very good. This property makes titanium very popular in many applications requiring lightweight and high strength, such as aerospace, automotive, sports equipment and other fields.

4. Corrosion resistance • Titanium has excellent corrosion resistance, even in a humid or salty environment is not easy to rust or corrosion. This further extends the service life of the titanium material, allowing it to maintain strength during long-term use.

5. Toughness • Titanium has good toughness and can absorb energy when subjected to impact or vibration without breaking. This makes titanium perform well under dynamic loads, such as in aerospace and sports equipment.






6. Temperature stability - Titanium can still maintain high strength and toughness at high temperatures, which makes it reliable to use in high temperature environments, such as engine parts and high temperature pipes.

• Titanium alloys are used in the manufacture of aircraft structural parts, engine components, etc., because they are light and strong and can withstand the harsh conditions of high altitude and high speed flight.


Titanium alloys are used in the manufacture of high-performance automotive components, such as connecting rods, valves, etc., to reduce weight and improve performance. Titanium alloys are used to make high-performance sports equipment such as golf clubs and bicycle frames because they are light, strong and resistant to corrosion.

The reason why titanium is both light and strong is that it has low density, high strength, high toughness and excellent corrosion resistance. These properties make titanium ideal for many high-performance applications.
