Non Ferrous Alloys

The proximity to the most important Italian espresso coffee machines producers and the long relationships with renewed international brands of sanitary faucet’s producers allowed Rubinetteria GST to have a deep experience about ecological Non Ferrous Alloys with low or zero Lead content. More than 10% of the production is dedicated to the Silicon Cu-Si ECObrass®/CuPHIN® (CW724R) necessary to comply the more strict American standards (Pb<0.2% on the part in contact with sanitary water) and European standard (10 mg/l di Pb). The ability in supply customers in different industrial sectors gave to GST the possibility to use and machine a very large range of Cu-Zn alloys.

For about two years GST realizes Aluminum components, especially in the automotive sector with 6000 series alloys.
