3J53

Product Description:

3J53 is a constant elastic alloy used to make frequency components. The alloy has an austenitic structure and has high elasticity and strength, low elastic modulus temperature coefficient, and good wave speed consistency. It can operate at 60 to 100°C. The resonant frequency of internally produced components basically does not change with temperature, so it is widely used in instruments, meters, communications, measurement and other fields.
