NBM Model 3 Free Machining DZR (Dezincification-Resistant) "Lead Free" Brass
With legislation looming for January 2010 requiring the change and replacement of
traditional free machining brass (C36000) with a lead free alternative, NBM is proud
to announce the development of new lead free grades that have been performing
with flying colors! Over the last 18 months we have been involved with the R&D for
this alternative, and we now have the solution.
