Excellent corrosion resistance, high strength, low specific gravity
Titanium’s specific gravity is 4.51, approximately 50% that of copper or nickel and approximately 60% that of stainless steel. This makes it extremely lightweight, enabling the reduction of structural weight.
Pure titanium has a specific strength of 60-160 kgf/cm2, and up to 500°C, it has the highest specific strength of any metal.
Titanium’s corrosion resistance is particularly noteworthy.
The metal’s corrosion resistance is achieved by forming a protective oxide film that is difficult to break down. Titanium’s corrosion is uniform, with little evidence of pitting or other localized, severe corrosion.
Normally, titanium is not subject to stress corrosion, fatigue corrosion, particle corrosion, or galvanic corrosion.
Titanium’s corrosion resistance is superior to that of stainless steel or copper alloys under a wide range of service conditions. In seawater, it rivals platinum in corrosion resistance.
Advantages as a light metal
Titanium has a specific gravity of 4.51, which is about 50% of that of copper or nickel and about 60% of that of stainless steel, making it extremely light, allowing for the reduction of structural weight.
high strength
The strength of pure titanium is 30-75 kgf/㎠, and that of alloy titanium is 60-160 kgf/㎠, which makes it the highest strength-to-weight ratio among other metal materials up to 500℃.
Excellent corrosion resistance
- Titanium’s corrosion resistance is particularly noteworthy. The metal’s corrosion resistance is achieved by forming a protective oxide film that is difficult to break down.
- Titanium’s corrosion is uniform, with little evidence of pitting or other localized, severe corrosion. It is not normally subject to stress corrosion, fatigue corrosion, or galvanic corrosion.
- Titanium’s corrosion resistance is superior to that of stainless steels and copper alloys under a wide range of service conditions, and in particular, its corrosion resistance in seawater rivals that of platinum.
- Therefore, titanium is an indispensable material even in high-temperature, high-pressure, and highly corrosive environments.
Non-toxic
Titanium is a harmless metal used for transplanting body tissues such as heart valves and artificial bones, and has recently been widely used in various fields such as medicine and accessories.
