This 0.005" Muscle Wire® (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. 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 Muscle Wire® 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: The datasheet found below is for Flexinol® actuator wire, that isn’t exactly like all Muscle Wire® but it’s close. Flexinol® Actuators Wires are made specifically for linear actuators to replace small motors or solenoids.

Features:

  • Length: 305mm
  • Diameter: 0.127mm
  • Current Required for Austenite Form: 200mA
  • Pull Force: 0.49lbs
  • Resistance: 1.9 ohms/inch

這0.005“肌肉Wire®的(又名形狀記憶鎳鈦諾 )是一英尺長的一塊鎳鈦合金,可以彎曲和合同時的熱量的具體數額或電流施加到它。如果你問自己:”什麼是魔法這個?!“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弱,低溫形態(馬氏體)導線之間的變化及其強,耐高溫形式(奧氏體)。

當肌肉Wire®的是在其馬氏體的形式,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:下面找到數據表是Flexinol®致動器線,這是不完全像所有的肌肉Wire®的,但已經很接近了。 Flexinol®執行器導線是為線性驅動器,以取代小型電機或螺線管專門製作。

特徵:

  • 長度:305毫米
  • 直徑:0.127毫米
  • 所需的電流為奧氏體型:小於200mA
  • 拉力:0.49lbs
  • 阻力位:1.9歐姆/英寸
