ZTE CARBONTM High Modulus tubes are specifically designed for extremely low CTE. Our precision processing and high stiffness materials makes them a good choice as affordable tubes for dimensionally stable structures such as optical benches, precision robotics and other similar structures.
Our tubes are specifically engineered to have essentially no residual distortion (hysterisis) in elongation, bend or twist after exposure to high or low temperatures in applications where such properties are required.
