It is a lead-free alternative alloy for sanitary fittings.

Alloy can be used as a medium-hard construction material.

The addition of phosphorus and sulfur replaces the lead in traditional machining materials.

Application: This alloy can be used for drinking water products, mainly used in the valve parts industry and as pipe connectors.
