The Dynalloy Muscle Wires® Actuator Wire 375 µm HT, 5m is a high-performance actuator wire designed for precise applications requiring controlled movement. This wire activates at a temperature of 90°C and offers a resistance of 8.3 ohms per meter, making it suitable for various engineering and robotics projects. It is engineered to handle a recommended current of 2250 mA and can exert a pull force of up to 2250 grams, with a deformation range of 3-5%. Note: This item is not for resale.
Works well, but it doesn't really have any benefits over thinner wires in terms of performance and it's harder to work with, so I would recommend buying the thinner ones.
