DSC-3N / DSC-3N HC
Related standardsJASO JC100
ApplicationsHeat sink bases, heat spreaders, high current terminals, busbars, lead frames, etc.
Copper alloy that is superior in strength and heat resistance to pure copper.
Ideal for heat sink bases, high current terminals, busbars, etc.
DSC-3N (DOWA Super Copper) is a 99.9% copper alloy containing trace amounts of additive elements.
It has better strength and heat resistance than C1020. It also has high thermal conductivity (350 W/m･K and higher).
In addition, we also have DSC-3N HC, which combines improved thermal conductivity to the superior characteristics of DSC-3N.
DSC-3N is a low-cost alloy and provides good balance of characteristics, suitable for high current terminals, busbars and thermal devices such as heat sink bases.
