FREE BRASS

The production of the new series of brass rods FREE BRASS, with a maximum lead content of 0,2% is an important development for the industry of FITCO, which now offers an innovative feedstock for the production of brass parts (for drinking purposes mainly) to the highest quality standards. New FREE BRASS alloys are certified under NSF / ANSI 372-G and are available from FITCO with the known standard round, hexagonal and square bars and are suitable for hot forging or machining. Due to the maximum lead content of 0.2% FREE BRASS products are fully compliant with the California Health and Safety Code (1953) and with Vermont Act 193 concerning lead in potable water systems but also based on Directive 2002/95/EC (RoHS), DM 174 del 06/04/2004, DIN 50930-6 Norm.

Properties

The characteristics of the FREE BRASS alloys are similar to those of lead-based alloys, which allow machining with slight modifications to the standard tools and almost the same machining parameters. Also, the returns of processing (swarf, pieces) can be recycled even if mixed with traditional lead-based alloys. It is also suitable for producing products to be used in gas industry, since these alloys exhibit minimal risk of sparking.
