Ti-6Al-4V is the most widely used of all the titanium alloys. The alloy can be supplied either in the solution annealed condition or age hardened. Used extensively in aerospace, medical, marine and chemical processing. It is used for connecting rods in internal combustion engines. It is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties (excluding thermal conductivity, which is about 60% lower in Grade 5 Ti than in CP Ti). Among its many advantages, it is heat treatable. This grade is an excellent combination of strength, corrosion resistance, weld and fabricability. In consequence, its uses are numerous such as for military aircraft or turbines. It is also used in surgical implants. Generally, it is used in applications up to 400˚C. Its properties are very similar to those of the 300 stainless steel series, especially 316.

Hastelloy C-276: This nickel alloy has a particularly high molybdenum level which, combined with the tungsten additions, gives it a very good crevice and pitting corrosion resistance. This makes it a particularly suitable material for use in severe environments such as pollution control and chemical processing.

Waspaloy is an age hardening austenitic nickel-based superalloy. The alloy is typically used in high temperature applications, particularly in gas turbines.
Waspaloy is an age hardening austenitic nickel-based superalloy. The alloy is typically used in high temperature applications, particularly in gas turbines.
It is an age-hardenable, nickel-based superalloy with excellent strength properties through temperatures of roughly 1800°F (980°C). Other characteristics of Waspaloy include good corrosion resistance, as well as being relatively impervious to oxidation making it well suited for service in extreme environments.
Waspaloy has useful strength at temperatures up to 1400-1600°F (760-870°C), and good oxidation resistance in gas turbine engine atmospheres up to 1600°F (870°C). The creep rupture strength of Waspaloy is superior to that of Alloy 718 at temperatures above 1150-1200°F (620-650°C). Short time hot tensile strength is inferior to RA718 at temperatures up to 1350°F (730°C).
Waspaloy is often encountered in extreme environments. It is common in gas turbine blades, seals, rings, shafts and turbine disks.
