Abstract

A wear-resistant alloy is provided that has a complex microstructure. from the microstructure includes a range of about 8 to about 17 wt % of zinc (Zn), a range of about 5 to about 8 wt % of tin (Sn), a range of about 1.0 to about 2.0 wt % of iron (Fe), and a balance of aluminum (Al).

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A wear-resistant alloy having a complex microstructure, comprising:
 a range of about 8 to about 17 wt % of zinc (Zn);   a range of about 5 to about 8 wt % of tin (Sn);   a range of about 1.0 to about 2.0 wt % of iron (Fe); and   a balance of aluminum (Al).   
     
     
         2 . The wear-resistant alloy of  claim 1 , further comprising:
 a range of about 1 to about 3 wt % of copper (Cu).   
     
     
         3 . The wear-resistant alloy of  claim 1 , further comprising:
 a range of about 0.3 to about 0.8 wt % of magnesium (Mg).   
     
     
         4 . The wear-resistant alloy of  claim 1 , further comprising:
 a range of about 1 to about 3 wt % of copper (Cu) and from about 0.3 to about 0.8 wt % of magnesium (Mg).   
     
     
         5 . A wear-resistant alloy having a complex microstructure, comprising:
 a range of about 8 to about 17 wt % of zinc (Zn);   a range of about 5 to about 8 wt % of bismuth (Bi);   a range of about 1.0 to about 2.0 wt % of iron (Fe); and   a balance of aluminum (Al).
