A drawn wire is a wire that has undergone cold working and is the last stage in the Nitinol wire manufacturing process. Drawn wire is very stiff, and to facilitate shape-setting it must be annealed in a furnace. The advantage of purchasing drawn wire is its lower price.
Price: ₪49 (0.25 mm)
The price listed above is for a 0.25 mm diameter wire, 1 metre in length. As noted, the wire arrives in a stiff state that makes shape-setting difficult; it must therefore be annealed at 250°–300°C for 10–15 minutes. Oxide can supply the wire after annealing — please submit a quote request.
