Brass alloy

Abstract

The present invention provides an environmental friendly brass alloy, including 0.4 to 0.8 wt % of aluminum; 0.6 to 1.6 wt % of nickel; 0.8 to 2.0 wt % of tin; more than 95.6 wt % of copper and zinc; and less than 0.1 wt % of iron, lead, phosphorous and impurities, wherein the copper is present in an amount ranging from 60 to 68 wt %.

1 . A brass alloy, comprising:
 0.4 to 0.8 wt % of aluminum;   0.6 to 1.6 wt % of nickel;   0.8 to 2.0 wt % of tin;   more than 95.6% of copper and zinc; and   less than 0.1 wt % of iron, lead, phosphorous and impurities.   
     
     
         2 . The brass alloy of  claim 1 , wherein the aluminum is present in an amount ranging from 0.5 to 0.6 wt %. 
     
     
         3 . The brass alloy of  claim 1 , wherein the nickel is present in an amount ranging from 0.8 to 1.4 wt %. 
     
     
         4 . The brass alloy of  claim 1 , wherein the tin is present in an amount ranging from 1.2 to 1.6 wt %. 
     
     
         5 . The brass alloy of  claim 1 , wherein the copper is present in an amount ranging from 60 to 68 wt %. 
     
     
         6 . The brass alloy of  claim 1 , wherein the copper is present in an amount ranging from 61 to 64 wt %. 
     
     
         7 . The brass alloy of  claim 1 , wherein the lead is present in an amount less than 0.05 wt %.
