Abstract

The present invention, in an embodiment, is cast product in the form of an aluminum alloy strip. The aluminum alloy strip includes 4 wt. % to 28 wt. % zinc and a variation of a weight percent of the zinc is 15% or less between a surface and a thickness center of the aluminum alloy strip.

Claims

exact text as granted — not AI-modified
We claim: 
     
         1 . A cast product comprising:
 an aluminum alloy strip;   wherein the aluminum alloy strip comprises:
 4 wt. % to 28 wt. % zinc; and 
   wherein a variation of a weight percent of the zinc is 15% or less between a surface and a thickness center of the aluminum alloy strip.   
     
     
         2 . The cast product of  claim 1 , wherein the aluminum alloy strip comprises 6 wt. % to 28 wt. % zinc. 
     
     
         3 . The cast product of  claim 1 , wherein the aluminum alloy strip comprises 8 wt. % to 28 wt. % zinc. 
     
     
         4 . The cast product of  claim 1 , wherein the aluminum alloy strip comprises 10 wt. % to 28 wt. % zinc. 
     
     
         5 . The cast product of  claim 1 , wherein the aluminum alloy strip comprises 4 wt. % to 15 wt. % zinc 
     
     
         6 . The cast product of  claim 1 , wherein the aluminum alloy strip comprises 6 wt. % to 12 wt. % zinc. 
     
     
         7 . The cast product of  claim 1 , wherein the aluminum alloy strip comprises 4 wt. % to 10 wt. % zinc. 
     
     
         8 . The cast product of  claim 1 , wherein the aluminum alloy strip comprises 4 wt. % to 8 wt. % zinc. 
     
     
         9 . The cast product of  claim 6 , wherein the variation of the zinc weight percent is 12% or less between the surface and the thickness center of the aluminum alloy strip. 
     
     
         10 . A cast product comprising:
 an aluminum alloy strip;   wherein the aluminum alloy strip comprises:
 (i) 4 wt. % to 28 wt. % zinc; 
 (ii) 1 wt. % to 3 wt. % copper; and 
 (iii) 1 wt. % to 3 wt. % magnesium; 
   wherein a variation of a weight percent of the zinc is 15% or less between a surface and a thickness center of the aluminum alloy strip.   
     
     
         11 . The cast product of  claim 10 , wherein the aluminum alloy strip comprises 4 wt. % to 15 wt. % zinc 
     
     
         12 . The cast product of  claim 10 , wherein the aluminum alloy strip comprises 4 wt. % to 12 wt. % zinc. 
     
     
         13 . The cast product of  claim 10 , wherein the aluminum alloy strip comprises 4 wt. % to 10 wt. % zinc. 
     
     
         14 . The cast product of  claim 10 , wherein the aluminum alloy strip comprises 1 wt. % to 2.5 wt. % copper. 
     
     
         15 . The cast product of  claim 10 , wherein the aluminum alloy strip comprises 1 wt. % to 2.0 wt. % copper. 
     
     
         16 . The cast product of  claim 10 , wherein the aluminum alloy strip comprises 1 wt. % to 1.5 wt. % copper. 
     
     
         17 . The cast product of  claim 10 , wherein the aluminum alloy strip comprises 1 wt. % to 2.5 wt. % magnesium. 
     
     
         18 . The cast product of  claim 10 , wherein the aluminum alloy strip comprises 1 wt. % to 2.0 wt. % magnesium. 
     
     
         19 . The cast product of  claim 10 , wherein the aluminum alloy strip comprises 1 wt. % to 1.5 wt. % magnesium. 
     
     
         20 . A cast product comprising:
 an aluminum alloy strip;   wherein the aluminum alloy strip comprises:
 (i) 4 wt. % to 28 wt. % zinc; and 
 (ii) 1 wt. % to 3 wt. % copper; 
   wherein a variation of a weight percent of the zinc is 15% or less between a surface and a thickness center of the aluminum alloy strip.
