Abstract

A wear-resistant alloy having a complex microstructure is provided. The microstructure includes a range of about 28 to about 38 wt % of zinc (Zn),a range of about 1 to about 3 wt % of tin (Sn), a range of about 6.2 to about 9.4 wt % of silicon (Si), 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 28 to about 38 wt % of zinc (Zn);   a range of about 1 to about 3 wt % of tin (Sn);   a range of about 6.2 to about 9.4 wt % of silicon (Si); 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 a range of 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 28 to about 38 wt % of zinc (Zn);   a range of about 1 to about 3 wt % of bismuth (Bi);   a range of about 6.2 to about 9.4 wt % of silicon (Si); and   a balance of aluminum (Al).
