This 0.012" Flexinol® Actuator Wires (aka shape memory Nitinol) is a one foot long piece of nickel-titanium alloy that can flex and contract when a specific amount of heat or current is applied to it and are made specifically for linear actuators to replace small motors or solenoids. If you are asking yourself “What sorcery is this?!” We assure you, this isn’t magic, it’s just simple science thanks to shape memory and a change between the wires weaker, low temperature form (martensitic) and its stronger, high temperature form (austenite).

When the Flexinol® is in its martensitic form, it can be formed and bent into different shapes. However, when an electrical current of ~200mA is applied to the wire, or is heated to ~100C it reverts to austenite form and recovers its previous shape with great force. Additionally, you can anneal at ~500C (use an industrial furnace or simply a lighter) it to whatever shape you would want, next once that current or heat is applied it will return to that new shape.

Note: These are the “HT” type wires.

Features:

  • Length: 305mm
  • Diameter: 0.30mm
  • Current Required for Austenite Form: 1.5A
  • Pull Force: 2.83lbs
  • Resistance: 0.31 ohms/inch

這個0.012“Flexinol®器電線(又名形狀記憶鎳鈦諾 )是一英尺長的一塊鎳鈦合金,可以彎曲和收縮時的熱特定量或電流施加到它,並且特別提出了線性致動器,以取代小型電機或螺線管。如果你問自己:“什麼妖術這是?!”我們向你保證,這不是魔術,它只是簡單的科學得益於形狀記憶和導線之間較弱的變化,低溫形式(馬氏體)其較強,高溫形態(奧氏體)。

當Flexinol®處於其馬氏體的形式,它可以形成並彎曲成不同的形狀。然而,當〜為200mA的電流被施加到金屬絲,或加熱到〜100℃它會恢復到奧氏體形式,並恢復其先前的形狀產生很大的壓力。此外,還可以在500℃〜退火(使用工業爐或者乾脆打火機),它到任何的形狀,你會想,接下來的一次應用,目前或熱將返回到新的形狀。

注意:這些是“HT”型的電線。

特徵:

  • 長度:305毫米
  • 直徑:0.30毫米
  • 所需的電流為奧氏體形式:1.5A
  • 拉力:2.83lbs
  • 阻力位:0.31歐姆/英寸
