| NiTinol wire is supplied in a
wide variety of different alloys, sizes, conditions and surfaces. For
a complete specification, the following parameters have to be defined: Alloy types: NiTinol is available in different alloy compositions, some of which are superelastic materials (Alloy N, S and C) and others are used as actuator materials (Alloy B, M, H and Flexinol). Thermomechanical condition (as cold worked, straight annealed, shape annealed or actuator optimized). Surface quality (standard dark grey oxide, light blue oxide, ground, polished or ultra-fine polished surfaces). Tolerances: standard tolerances are dependant on the diameter. For example a wire of 0,30 to 0,61 mm typically is supplied with a tolerance window of ±0.01 mm. Conditions: • Af-temperatures between -100°C up to +120°C (standard alloys -25°C up to +120°C) • alloy fabrication possible upon special request • Surface conditions from shiny black oxide, amber/brown oxide over ground up to ultra-fine polished surfaces • Thermomechanical Conditions from as cold-worked with different degrees of coldwork to straight annealed or set into specific shapes (springs, hooks, etc.)
