Abstract

The present disclosure provides an aluminum (Al) alloy, for general casting, and a technique for producing the same. The Al alloy includes Al, Si in the range of 5 to 13 wt %, Ti in the range of 2 to 7 wt % and B in the range of 1 to 3 wt %. According to the disclosure, a TiB 2 compound may be formed in the Al alloy, where the ratio of Ti:B may range from 2 to 2.5 wt %. The Al alloy of the disclosure has improved elasticity, and is suitable for general casting processes such as, for example, high pressure casting process.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An aluminum alloy, comprising: Al, Si in the range of 5 to 13 wt %, Ti in the range of 2 to 7 wt %, and B in the range of 1 to 3 wt %. 
     
     
         2 . The aluminum alloy of  claim 1 , wherein a TiB 2  compound is formed therein. 
     
     
         3 . The aluminum alloy of  claim 1 , further comprising: Fe in the range of 1.0 to 1.5 wt %, Cu in the range of 1.5 to 3.5 wt %, Mn in the range of 0.5 wt % or less, Mg in the range of 0.3 wt % or less, Ni in the range of 0.5 wt % or less, and Zn in the range of 1 wt % or less. 
     
     
         4 . The aluminum alloy of  claim 3 , wherein the amount of Mg, Ni, and Zn is more than 0 wt %. 
     
     
         5 . The aluminum alloy of  claim 1 , further comprising Fe in the range of 0.2 wt % or less, Cu in the range of 0.2 wt % or less, Mn in the range of 0.1 wt % or less, Mg in the range of 0.25 to 0.45 wt %, Ni in the range of 0.05 wt % or less, and Zn in the range of 0.1 wt % or less. 
     
     
         6 . The aluminum alloy of  claim 5 , wherein the amount of Fe, Cu, Mn, Mg, Ni, and Zn is more than 0 wt %. 
     
     
         7 . The aluminum alloy of  claim 1 , wherein the ratio of B:Ti is 1:2˜2.5. 
     
     
         8 . The aluminum alloy of  claim 7 , wherein the ratio of B:Ti is 1:2. 
     
     
         9 . The aluminum alloy of  claim 7 , wherein the ratio of B:Ti is 1:2.1. 
     
     
         10 . The aluminum alloy of  claim 7 , wherein the ratio of B:Ti is 1:2.2. 
     
     
         11 . The aluminum alloy of  claim 7 , wherein the ratio of B:Ti is 1:2.3. 
     
     
         12 . The aluminum alloy of  claim 7 , wherein the ratio of B:Ti is 1:2.4. 
     
     
         13 . The aluminum alloy of  claim 7 , wherein the ratio of B:Ti is 1:2.5. 
     
     
         14 . A method for producing the aluminum alloy of  claim 1 , comprising:
 mixing a molten Al—Ti-based alloy comprising Ti in the range of 5 to 10 wt % and a molten Al—B-based alloy comprising B in the range of 2 to 10 wt % together, thereby forming the aluminum alloy.   
     
     
         15 . The method of  claim 14 , wherein a TiB 2  compound is formed in the aluminum alloy. 
     
     
         16 . The method of  claim 14 , wherein the ratio of B:Ti is 1:2. 
     
     
         17 . The method of  claim 14 , wherein the ratio of B:Ti is 1:2.1. 
     
     
         18 . The method of  claim 14 , wherein the ratio of B:Ti is 1:2.2. 
     
     
         19 . The method of  claim 14 , wherein the ratio of B:Ti is 1:2.3. 
     
     
         20 . The method of  claim 14 , wherein the ratio of B:Ti is 1:2.4. 
     
     
         21 . The method of  claim 14 , wherein the ratio of B:Ti is 1:2.5.
