Nitinol Superelastic Wire ASTM F2063 All Sizes

Order in any length by selecting the diameter, increments (feet or meters) and entering the quantity desired. Longer quantities automatically ship on a spool.

Superelastic nitinol is capable of stretching up to 30% of its length without permanent deformation.

The formulation is almost identical to our shape memory alloys, but this material is super elastic at above freezing temperatures and it will not change its shape upon application of heat. If you are looking for wire that changes shape upon application of heat, use the link above. Technically, superelastic nitinol exhibits a very mild memory effect, with a transition phase at approximately -10ºC, so if you intend to use the material in a very cold environment, we recommend you test a sample to see how it behaves. It will become soft at around -15 to -20°C. If you need wire to remain springy at such cold temperatures, such as fishing in the arctics, you should try the -20°C alloy available here instead.

CHARACTERISTICS

The wire has a lustrous titanium color (dark grey) with a bluish oxide tint on its surface. When freshly cut, the inner core is nickel white. Nitinol is very abrasion resistant and has self-healing properties, so the wire is quite hard to cut and kink. It does not require any special handling or protections from oxidation or moisture, and is non-toxic.

PURCHASE OPTIONS

Select your desired unit of measure, and use the quantity selector to choose your ideal length in metric, imperial or by weight.Choose your desired diameter. 0.5mm is 24 gauge, 0.8mm = 20 gauge, 1mm = 18 gauge, and 2mm = 12 AWG.
When you order multiple quantities we will cut one long section off of the pictured roll so you can procure uncut sections and cut later as you please.
