低温グレードのニチノールとして分類される形状記憶は、高温の工業用途での使用により適しています。 形状記憶グレードはまた、ニチノールアクチュエーターでの利用でも注目されつつあります。
形状記憶の特性は工業用用途だけにとどまりません。 医療用では体温(37°C (98.6°F))での相変態を利用する設計がされています。
形状記憶グレードの使用例:
NiTi #5 is commonly used in high temperature actuators.
NiTi #6 is commonly used in high temperature actuators.
NiTi #8 is typically used in applications that require a phase transformation at body temperature.
All binary Nitinol grades meet the chemistry requirements set forth by ASTM F2063 for use in surgical implants.
Our unique product offerings could be just what you're looking for if the typical grades of Nitinol aren't quite right. From ultra-smooth oxide free Silk® Nitinol, to ultra-stiff USN® wire, you'll find all kinds of material solutions right here.
Actuator wire can perform work through a phase transformation. Simply put, a bias load or force will elongate the wire, and a phase change induced using heat or electricity will cause the wire to contract. As the material cycles, contracting as heat is applied and elongating as it cools, the actuator performs work, which could include pulling a release valve, lifting loads, or otherwise applying force. Using a wire to perform work has several advantages. At the forefront is its high work density, meaning it can generate a large amount of work for a relatively small footprint. Another benefit is its comparative silence by eliminating the need for noisy motors.

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. |
