4.Characteristics:
Small frequency, constant temperature coefficient, elastic alloy.
High elastic modulus and strength, low temperature coefficient of elastic modulus,
good wave velocity uniformity.
5.Applications:
Between the temperature range of- 40 ℃ ~ 80 ℃ 3J53 has low frequent temperature coefficient,
used in the mechanical filter in oscillator, words such as the leaf spring in vibration relay component.
Therefore, can be used to make mechanical oscillator, a tuning fork, diaphragm filter and reed, etc.
In addition, in the field of materials, and 3J53 can be used to make round steel, forgings, flange, rod, tube and steel belt, and so on.
