Medical Nitinol wire for guide wire

The ingredients are strictly subdivided to reduce the phase change temperature fluctuation, so that the performance of the material and equipment is more consistent

 

As one of the key indicators of superelasticity of nickel-titanium alloys, the actual action Af temperature is often used to evaluate the effective performance of superelasticity. ASTM F2063-18 stipulates that the nickel content is 54.5~57.0mass%, but because the actual action Af temperature is very sensitive to the composition, it is extremely important to subdivide the composition of the nickel-titanium alloy. Therefore, AprilTi uses the subdivision alloy code to identify the alloy.

Alloy Code A B S C D E J K L
Actual action temperature after heat treatment ℃ 70+/-10 30+/-10 25+/-5 17+/-7  10+/-7 0-15 +30+/-10 30+/-10 -20+/-15

Delivery status:

Straightening the hyperelastic state (SE)

Cold-worked condition (CW), requiring subsequent heat treatment

 

Wire shape:

Nitinol round wire

Nickel-titanium flat wire, square wire
