So as to drive the price of the quartz crystal resonator bracket to be incapable of being reduced. The 4J50 material mainly comprises iron and nickel alloy, does not contain Co, is low in price and has a smaller thermal expansion coefficient than the 4J29 material, but when the material is used as a quartz crystal resonator bracket lead wire, the highest airtightness of a sintered product can only reach 1 x 10-6pa·m3The tensile strength can only reach 5Kg of load in the direction of the lead wire vertical to the substrate and the requirement of keeping 30s, the maximum hardness of the 4J50 material can only reach 185HV, and the conductivity can only be as low as 0.44 omega mm2Therefore, the 4J50 material is used as a lead wire of the quartz crystal resonator bracket, and the performance of the quartz crystal resonator bracket is still to be further improved.
