Product Details

Titanium and titanium alloys are attractive structural materials due to their high strength, low density, and excellent corrosion resistance. However, even though titanium is the fourth most abundant element in the Earth’s crust, the cost of titanium is high due to its high melting point and extreme reactivity. The high cost includes both the mill operations (extraction, ingot melting, and primary working) as well as many of the secondary operations conducted by the user. The advantages of titanium include:
The high strength-to-weight ratio of titanium alloys allows them to replace steel in many applications requiring high strength and fracture toughness. With a density of 4.5 g/cm3 (0.16 lb/in.3), titanium alloys are only about ½ as heavy as steel and nickel-base superalloys, yielding excellent strength-to-weight ratios.
Titanium alloys have much better fatigue strength than the other lightweight alloys, such as those of aluminum and magnesium.
Titanium alloys can operate at elevated temperatures, as high as 370 to 590 °C (700 to 1100 °F) depending on the specific alloy.
The corrosion resistance of titanium alloys is superior to both steel and aluminum alloys.
