COPPER & BRASS :

Quarter Hard – Hard enough to have some resistance, but soft enough to double seam without cracking.
 
Half Hard – A temper suitable for punching, blanking and simple forming. Will double seam on the lighter gauges.
 
Hard – Too stiff to be worked beyond a right angle bend. Used mostly for flat and straight work.
 
Spring – Hard enough to resume position after a definite deflection. Extra Spring – As hard as brass can be rolled. Used for extraordinarily stiff spring work.
 
Bending Temper – A special temper used in the manufacture of tubing; just soft enough to take ordinary bends without losing its shape or denting badly, and sufficiently close grained to take a high polish.
