초탄성 나이티놀

체온 또는 실온 정도로 서늘한 환경에서 초탄성 나이티놀의 상 변환 덕분에 이와 같이 더 차가운 그레이드는 의료 기기 또는 기타 저온 응용 분야에서 보다 널리 사용됩니다.

초탕성 나이티놀의 사용 사례:

NiTi #1 is commonly used for applications requiring superelasticity at room and body temperature. Typical applications include guidewires, stents, stylets, forming mandrels, stone retrieval baskets, and orthodontic files.

NiTi #2 is a ternary grade of Nitinol containing additions of chromium (0.2-0.3% Cr by weight) and is often used in applications requiring increased loading and unloading plateau stresses and decreased transformation temperatures.

NiTi #3 is a ternary grade of Nitinol containing additions of cobalt (1.0-2.0% Co by weight) and is often used to maximize loading and unloading plateau stresses over other Nitinol grades. Decreased transformation temperatures also allow this grade of Nitinol to remain superelastic in colder temperature applications.

NiTi #4 has the warmest transformation temperatures of our superelastic grades, resulting in decreased modulus and plateau stresses and improved fatigue performance at room and body temperatures when compared to other superelastic Nitinol grades with equivalent previous cold work and heat treatments.

NiTi #9 is the coldest grade of binary Nitinol that we offer and is used for applications requiring superelasticity at colder temperatures.

After an appropriate heat treatment, superelastic Nitinol will accommodate strain of up to 8% in tension without significant permanent deformation, when tested at room temperature which is above the transformation temperature of the material.

All Binary Nitinol grades meet the chemistry requirements set forth by ASTM F2063 for use in surgical implants.

Permanent set < 0.5% after strained to 8%. Results are typical for round wire diameters from 0.03 mm to 1.02 mm [0.001 in to 0.04 in]. All mechanical testing conducted at 22°C ± 2°C [71.6°F ± 3.6°F]. Our video library can help you learn about active Af testing using the Fort Wayne Metals Manual Method and test methods conforming to ASTM F2082, such as LVDT or the vision system. You can compare the two test methods by reading the whitepaper. Please note that a correlation study may be required to switch test methods on an existing part.
