Tungsten is known for its high strength and hardness, which makes it a suitable material for microscale mechanical applications. Tungsten has a tensile strength of around 550-620 MPa, which is higher than that of most other common materials used in microscale mechanical applications, such as stainless steel and titanium. In addition, tungsten has a high modulus of elasticity, which means it can resist deformation under stress better than other materials. This makes tungsten needles an ideal choice for microscale mechanical applications that require high strength and stiffness, such as microscale actuators and sensors.
