Aluminum alloy

Abstract

Disclosed is an aluminum alloy, which is made of a composition including about 0.7˜7.5 wt % of Ti, about 0.2˜1.5 wt % of B and a residue of Al as a main component, wherein the aluminum alloy is formed by melting the composition at about 950˜1000° C.

What is claimed is: 
     
         1 . An aluminum alloy, which is made of a composition comprising about 0.7˜7.5 wt % of Ti, about 0.2˜1.5 wt % of B and a residue of Al as a main component, wherein the aluminum alloy is formed by melting the composition at about 950˜1000° C. 
     
     
         2 . An aluminum alloy, which is made of a composition comprising about 5˜10 wt % of Ti, about 0.2˜1.5 wt % of B and a residue of Al as a main component, wherein a ratio of Ti to B is about 3.5˜5:1. 
     
     
         3 . The aluminum alloy of  claim 1 , wherein the melting temperature is maintained for about 20˜30 minutes. 
     
     
         4 . The aluminum alloy of  claim 2 , wherein the aluminum alloy is formed by melting the composition at about 950˜1000° C. 
     
     
         5 . The aluminum alloy of  claim 4 , wherein the melting temperature is maintained for about 20˜30 minutes. 
     
     
         6 . A method of forming an aluminum alloy comprising:
 Providing a composition comprising about 0.7˜7.5 wt % of Ti, about 0.2˜1.5 wt % of B and a residue of Al as a main component; and   melting the composition at about 950˜1000° C.   
     
     
         7 . The method of  claim 6 , wherein a ratio of Ti to B is about 3.5˜5:1. 
     
     
         8 . The method of  claim 6 , wherein the melting temperature is maintained for about 20˜30 minutes.
