Super alloy L605 (aka Haynes 25) is a cobalt, nickel, chromium and tungsten alloy originally developed for use in the airplane industry. A non-magnetic, stainless steel alloy with an exceptionally hard surface, L605 can be polished to a high, mirror like sheen. Because it maintains its strength at temperatures up to 1800 degrees Fahrenheit, it is often used in mufflers, high temperatures kilns and gas turbine engines. L605’s excellent ductility and welding properties also make it an ideal material for drug-eluting stents. Tube Hollows International drills custom tubing starting hollows for customers across the globe. Our ability to provide highly concentric, high depth-to-ID ratio L605 custom tubing has positioned us as a world leader in drilling this alloy.
