5.Other Materials we can supply--- GR1, GR3, GR5, GR7, GR9, GR11,GR12, GR16,GR17.
GR1—Ti Grade 1 is the softest titanium with the highest ductility, good cold formability which gives Gr1 an excellent resistance from mild to high oxidization.
GR5—Ti Grade 5 has very high strength but relatively low dectility. The main application of this alloy is in aircraft and spacecraft.Offshore use is growing. The alloy is weldable and can be precipitation hardened.
GR7---Ti Grade 7, most corrosion-resistant titanium alloy offering outstanding resistance to general and localized crevice corrosion in a wide range of oxidizing and reducing acid enviroments including chlorides, with a good balance of moderate strength, reasonable ductility and excellent weldability. Physical and mechanical properties equivalent to Grade 2.
GR9---Ti Grade 9 is sometimes referred to as “half 6-4". It offers 10~50%higher strength than C.P. grades but is more formable and weldable than Ti-6Al-4V. Gr9 combines strength, weldability and formability. The alloy has excellent formability plus higher tensile strength than the strongest unalloyed grade.
GR12—Ti Grade 12 is highly weldable, exhibiting improved strength allowable at increased temperatures, combined with superior crevice corrosion resistance, and excellent resistance under oxidizing to mildly reducing conditions, especially chlorides.
GR16---Ti Grade 16 is corrosion-resistant material offering outstanding resistance to general and localized crevice corrosion in a wide range of oxidizing and reducing acid environments including chlorides. Has a good balance of moderate strength, reasonable ductility and excellent weldability.
Overview
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.
