Embodiment Construction
[0025] The inventors used the chromium copper (Cr: 0.84% by weight) used in the original contact tip and the invented product to form the four test samples in Table 1. First, 4 kinds of billets of test samples were cast and hot-extruded into rods with a diameter of 32 mm. Then, it was heat-retained at 960°C for about 1 hour for solution treatment, and stretched into a rod with a diameter of 25 mm and a length of 50 mm. After aging treatment at 455°C for about 3 hours, the desired sample is obtained. The HV hardness and electrical conductivity of the four samples after the aging treatment are shown in Table 1. The Te addition amount is in the range of 0.01-1.0% by weight, the electrical conductivity is slightly lower, and the HV hardness is slightly increased.
