NBM Lead Free Machining 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.
