いたりして、仕上がり精度が悪いという問題があった。(Problems to be Solved by the Invention) By the way, the above spring electrode is made of Pt-Ir30w.
After the t% alloy wire is processed into a coil, it returns due to springback, which causes the coil pitch to be uneven, the coil diameter to vary, and the coil length to vary, resulting in poor finishing accuracy. There was a problem.

であることが判った。Therefore, the present inventor investigated that the Pt-Ir 30wt% alloy wire returns by springback after being processed into a coil shape, and found that the mechanical properties of the PtPt-1000% alloy are a hardness of 450 HV and a tensile strength of 150 kg. ,/-
It turned out to be.

ＨＶ。(Means for Solving the Problems) A method for manufacturing a spring electrode of the present invention to solve the above problems is to heat-treat a Pt-Ir 20-40wt% alloy wire at 900-1200°C to have a hardness of 350-400°C.

-Ir 20~40wt% alloy wire is heat treated to hardness 3
50-400HV, tensile strength 100-130kg/
The reason for - is that the hardness is 400HV and the tensile strength is 1'3.
If it exceeds 0kg/nni, the coil will not return to the specified dimensions after being processed into a coil, and the hardness will be less than 350HV and the tensile strength will be 100kg.
This is because if it is less than /-, the hardness and springiness necessary for use as a spring electrode cannot be obtained.

The reason for this is that outside this range, HV350~4
This is because a hardness of 0.00 and a tensile strength of 110 to 130 kg/- cannot be obtained.

t-Ir 20-40wt% alloy wire is heat treated to have a hardness of 350-400HV and a tensile strength of 100-130k.
Since the spring electrode is processed into a coil after g/lTr[l, the resulting spring electrode has an equal coil pitch, a constant coil diameter, and a constant coil length, resulting in high finishing accuracy.
