| (μΩm) | (Mpa) | (Gpa) | (g/cm3) | (×10 -6/ﾟC) |
| Electrode | 4.2-5.8 | 10.0-15.0 | 9.0-13.0 | 1.68-1.74 | 1.0-1.4 |
| Nippe | 3.0-4.0 | 20.0-30.0 | 15.0-21.0 | 1.80-1.86 | 0.9-1.2 |
Package
Separated package---The electrodes and nipples are packaged separately.
Pre-connection package--- The nipples are connected with one end of electrode body in advance, and then both of them are packaged by wooden rafters, strapped with steel bands outside, the threaded nipples and end faces are covered by foamed plastic caps in order to protect them from damage.
