718 Nickel Bar, Wire, Rod
Alloy 718 is a precipitation-hardening nickel-chromium alloy containing significant amounts of iron, columbium, and molybdenum, along with lesser amounts of aluminum and titanium. It is sometimes referred to as a “super alloy”.
718 is commonly used in High temperature bolts, nuts and fasteners, Airframe parts, Gas turbine engines, Cryogenic tanks and Nuclear engineering applications.
