HASTELLOY® X alloy is a nickel-chromium-iron-molybdenum alloy that has been in service in aerospace applications for nearly 50 years. The alloy offers very good balance of high-temperature strength, oxidation resistance, and fabricability. This alloy is widely used for aircraft and industrial gas turbine engine fabricated combustor and exhaust components, such as transition ducts, combustor cans, spray bars and flame holders, afterburners, and tailpipes.

HAYNES® Ti-3Al-2.5-V alloy
HAYNES® Ti-3Al-2.5-V alloy was developed for aircraft hydraulic and fuel systems transmission lines, primarily because of its high strength-to-weight ratio. This ratio proves to be a major advantage when used for hydraulic tubing lines to provide required strength levels, but more importantly, reducing weight by as much as 43% when compared to stainless steel.
