CW510L
DESCRIPTION
CW510L is a lead free material which is however quite suitable for machining due to its structural constitution. CW510 can be 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.
