CW510L
CW510L Spec SheetCW510L is a lead-free material which is however quite suitable for machining Due to its structural constitution. CW510 can be therefore used as a cost-effective Replacement for conventional lead-containing machining brass provided that it must not meet high requirements as regards mechanical properties and corrosion Resistance.
