Each of the aforementioned three metals has its advantages and disadvantages. For example, nickel has a low-cost property, but its emission characteristics of emitted electrons are poor. Crane (M) has high temperature resistance and good electron emission characteristics, but tungsten or molybdenum has the disadvantage of being too costly. Therefore, it is still practical to use low cost 'but electron emission characteristics and lifetime phase, poor recording (Ni) Electrode discharge cup. β Ideal method is to make the discharge cup with alloy, and achieve good electron emission characteristics, and is resistant to temperature and long life. For example, nickel-iron-molybdenum alloy is used as the discharge cup, which can reduce the cost and achieve good results. Emission characteristics Although iron-molybdenum alloys have good performance in terms of material cost, electron-emitting characteristics or high-temperature resistance characteristics, nickel-iron-indium alloys have high hardness, and the punching ratio is relatively difficult to process. That is to say, when a nickel-iron-molybdenum alloy discharge cup is produced by stamping, it is only possible to produce a discharge cup having a relatively short length. In addition to the aforementioned high cost of tungsten, cranes (W) or cans cannot make two press ratios. The discharge cup.
