CarTech® Low Expansion 43-PH
The alloy's constant modulus of elasticity, inherent high strength, good formability, adjustable elastic coefficient and low mechanical hysteresis have been factors in its consideration for use in a wide variety of applications in precision devices in which the effects of ambient temperature variations must be held to low limits.
Due to its insensitivity to temperature changes, the temperature compensation of CarTech Low Expansion 43-PH is extremely reliable and, in some cases, mechanical linkage corrections may be unnecessary.
The thermal elastic coefficient (TEC) of this alloy can be adjusted to zero, or some value near zero, by varying the aging temperature and the degree of prior cold work applied to the material.
Applications:
CarTech Low Expansion 43-PH could be considered for use in many precision devices where a stressed member must maintain a constant stiffness or deflection, deliver a constant force, or where a vibrating member must maintain a constant frequency regardless of the ambient temperature in the range of -50°F to 150°F (-47°C to 66°C).
Typical applications have included springs, diaphragms and supports in timing and measuring devices, continuous weighing systems, flow meters, gyro suspensions, motor speed switches, bourdon tubes and tuning forks.
