Sandvik F562 is a non-magnetic nickel-cobalt base alloy that has a unique combination of properties: ultra high strength, toughness, ductility and excellent corrosion resistance. Sandvik F562LTi is the low titanium version of Sandvik F562.

The alloy is cold worked to obtain strength level of 1790-2205 MPa (260 to 320 ksi). It can also be aged in the work hardened condition to achieve higher strengths. A leading material for permanent implants, Sandvik F562 is vacuum melted in multiple steps for extreme cleanliness.

Sandvik F562 is resistant to corrosion in hydrogen sulfide, salt water and other chloride solutions as well as mineral acids (nitric, hydrochloric, sulfuric).

In addition, it has exceptional resistance to crevice and stress corrosion cracking having been operationally proven in sea water and hostile environments.

For medical use, Sandvik F562 is delivered with the highest surface finish (Medical class) in order to maximize the fatigue strength, which is critical in implant devices such as lead wires for pacemakers and heart valve supports.
