Characteristic as below：
With low frequency temperature coefficient and high mechanical quality factor .
3J40 is a high-hardness, high-strength, non-magnetic, corrosion-resistant, and highly elastic alloy.
3J40 elastic alloy is a precision alloy used to manufacture elastic components in precision instruments, such as elastic sensors, energy storage components, frequency components, etc. Longji tells you that in addition to good elastic properties, 3J40 elastic alloy also has properties such as non-magnetic, high plastic deformation resistivity, high hardness, low resistivity, low temperature coefficient of elastic modulus, and low internal friction. 3J40 elastic alloys include high elastic alloys and constant elastic alloys. The former has high elastic limit, low elastic effect and good heat resistance. The modulus of elasticity of the latter does not change much with temperature within a certain temperature range, so it is also called “Elinvar alloy”.
Heat treatment regime: heating at 600 degrees for five hours, then cooling to 300 degrees, and then turning off the process energy. Cool naturally to 200 degrees (the door cannot be opened during the cooling process), and then take it out
Processing conditions and application:
It is used to make various forms of mechanical filter vibrator.
