No, it's the other way round for Copper alloys compared to Steel.

Copper Alloys :
To Anneal, heat to dull red , hold for 1 hour per inch thickness, and quench.
To Harden, heat to dull red , hold for 1 hour per inch thickness, and cool slowly.

Steel Alloys :
To Anneal, heat to bright red, hold for 1 hour per inch thickness, and
cool very slowly.
To Harden, heat to bright red, hold for one hour per inch thickness
and quench in water, brine or oil, depending on grade. Temper while
still warm or it will be dangerously brittle.
