Product Description

Active af temperature is one of the critical properties of Nitinol that can determine the effective super-elastic performance of the alloy. Although all the major Ni content in the range of 54.5~57.0mass% conforms the ASTM F2063-18 standard spec, its Af is very sensitive to the chemical composition, detailed grading of Nitinol composition is of crucial importance. This is why at Peiertech we use detailed and verified Nitinol code to identify the alloy.
