Inconel X750 Spring Manufacturer

Inconel X-750 is a nickel-chromium-iron alloy quite similar to Inconel except that the addition of small amounts of aluminum, columbium, and titanium change it to a precipitation-hardenable alloy. It is often used in larger sizes than are customarily used for Inconel; it can withstand higher temperatures and is nonmagnetic.
