It is a question concerning the IRIDIUM POWER that is often.
|
||
|---|---|---|
| Iridium is the same type of precious metal as platinum. It is characterized by its extremely high melting point and great strength. |
 |
 |
| Melting point |
| The melting point of iridium is approximately 680°C higher than that of platinum and is difficult to melt even in the high temperatures produced by electrical discharges and combustion. |
|
| Strength |
| Iridium has high material strength compared to other materials and provides stable performance under heavier driving conditions. |
|
| Electrical resistance |
| Because the electrical resistance is lower than platinum and the base material of electrodes, nickel, iridium is suitable for use in spark plug electrodes. |
|
| Hardness |
| Iridium is harder than other materials and has great material strength. |
