- tough pitch copper having high conductivity and high thermal conductivity is used as a copper material for electrical components.
- the conductivity of tough pitch copper JIS C1100 is 100% IACS or higher according to the JIS.
- heat resistance of tough pitch copper is unknown, when processing rate is high, there is concern about softening by holding for a long time in an atmosphere at 80 ° C.
- the power distribution member for a car
- the power distribution member will be exposed to a relatively high temperature environment for a long time. Therefore, it is required that the physical strength does not deteriorate even if exposed to such a harsh environment for a long time.
- the strength of the wire crimping portion depends on the yield strength of the material. Therefore, for example, when a material having poor heat resistance such as tough pitch copper is used, a reduction in proof stress due to recrystallization easily occurs. As a result, the crimp strength of the crimped part is reduced and the reliability for the required quality is inferior. It will be.
- the same characteristic is calculated
- copper alloys having high conductivity and good heat resistance will be used for applications that are exposed to a relatively high temperature environment as described above for a long time, such as iron-containing copper, tin-containing copper, etc.
