Ecobrass is a term for brass alloys that contain less than 0.1% lead. Thus, they comply with current standards for use in contact with drinking water.

The alloy exhibits similar mechanical properties to other lead-containing brass grades. It is suitable for both casting and forming processes. Its notable properties include good machinability, corrosion resistance, resistance to stress corrosion cracking, polishability, and good hard and soft solderability.

These properties result from the significantly lower zinc content compared to Ms58 and the additions of silicon and phosphorus. This combination largely compensates for the absence of lead for machinability and the softer α-structure, compared to the harder α-β-structure of Ms58.

The silicon in the alloy leads to increased hardness and good machinability. The low phosphorus content deoxidizes the melt and makes it more fluid. Silicon and phosphorus also counteract zinc evaporation during melting. Nevertheless, the use of slag binders for copper alloys during the melting process is recommended.

Therefore, if it is important to produce lead-free castings or if you want to cold or hot form the casting later, this alloy is preferable to Ms58.
