Commercially pure titanium (CP) is known for its excellent corrosion resistance and formability. It is available in various grades, with Grade 1 offering the highest ductility and Grade 4 providing superior strength. These sheets are often used in the medical and chemical industries due to their biocompatibility.
2. Titanium Alloy Sheets
Titanium alloys, such as Ti-6Al-4V, combine titanium with other elements like aluminum and vanadium to enhance strength and other mechanical properties. These alloys are widely used in aerospace applications, where lightweight yet strong materials are essential.
3. Alpha and Beta Titanium Alloys
Alpha alloys, such as Ti-3Al-2.5V, are known for their high-temperature strength and good weldability. Beta alloys, like Ti-15V-3Cr-3Sn, offer excellent ductility and are commonly used in aerospace and defense applications. These materials are designed to withstand extreme conditions while maintaining structural integrity.
4. Titanium Composites
These sheets combine titanium with other materials to enhance performance characteristics, making them ideal for specialized applications such as sports equipment and high-stress components.
