Abstract
One exemplary embodiment includes a cast alloy including Al present in an amount of about 6.5 wt % to about 9.0 wt %; Sn present in an amount of about 1.0 wt % to about 3.0 wt %; Ce present in an amount of about 0 wt % to about 1.0 wt %; and, Mg comprising a balance of the alloy minus an amount of minor and trace elements wherein Mg is present at an amount of greater than about 85 wt %.
Claims
exact text as granted — not AI-modified1 . A cast alloy comprising:
Al present in an amount of about 6.5 wt % to about 9.0 wt %; Sn present in an amount of about 1.0 wt % to about 3.0 wt %; Ce present in an amount of about 0 wt % to about 1.0 wt %; Y present in an amount of about 0 wt % to about 1.0 wt %; and, Mg comprising a balance of the alloy minus an amount of minor and trace elements wherein Mg is present at an amount of greater than about 85 wt %.
2 . The alloy of claim 1 , wherein at least one of Ce or Y is present in an amount of about 0.01 wt % to about 1.0 wt %.
3 . The alloy of claim 1 , wherein Ce is present in an amount of about 0.05 wt % to about 0.8 wt %, or wherein Y is present in an amount of about 0.1 wt % to about 0.5 wt %.
4 . The alloy of claim 1 , wherein Ce is present in an amount of about 0.2 wt % to about 0.5 wt %, or wherein Y is present in an amount of about 0.1 wt % to about 0.3 wt %.
5 . The alloy of claim 2 , wherein Sn is present at a level of about 1.0 wt % to about 2.5 wt %.
6 . The alloy of claim 2 , wherein Sn is present at a level of about 2.5 wt % to about 3.0 wt %.
7 . The alloy of claim 2 , wherein Al is present at a level of about 6.8 wt % to about 8.0 wt %.
8 . The alloy of claim 2 , wherein Al is present at a level of about 8.0 wt % to about 9.0 wt %.
9 . The alloy of claim 1 , further comprising Zn present at a maximum level of about 0.3 wt %.
10 . The alloy of claim 1 , further comprising Mn present at a level of about 0.2 wt % to about 0.6 wt %
11 . A cast alloy comprising:
Al present in an amount of about 6.5 wt % to about 9.0 wt %; Sn present in an amount of about 1.0 wt % to about 3.0 wt %; Ce present in an amount of about 0.01 wt % to about 1.0 wt %; Y present in an amount of about 0 wt % to about 1.0 wt %; and, Mg comprising a balance of the alloy minus an amount of minor and trace elements wherein Mg is present at an amount of greater than about 85 wt %.
12 . The alloy of claim 11 , wherein Ce is present in an amount of about 0.05 wt % to about 0.8 wt % or wherein Y is present in an amount of about 0 wt % to about 1 wt %.
13 . The alloy of claim 11 , wherein Ce is present in an amount of about 0.1 wt % to about 0.5 wt % or wherein Y is present in an amount of about 0.1 wt % to about 0.5 wt %.
14 . The alloy of claim 11 , wherein Ce is present in an amount of about 0.2 wt % to about 0.5 wt % or wherein Y is present in an amount of about 0.1 wt % to about 0.3 wt %.
15 . The alloy of claim 12 , wherein Sn is present at a level of about 1.0 wt % to about 2.5 wt %.
16 . The alloy of claim 12 , wherein Sn is present at a level of about 2.5 wt % to about 3.0 wt %.
17 . The alloy of claim 13 , wherein Al is present at a level of about 6.8 wt % to about 8.0 wt %.
18 . The alloy of claim 13 , wherein Al is present at a level of about 8.0 wt % to about 9.0 wt %.
19 . The alloy of claim 11 , further comprising Zn present at a maximum level of about 0.3 wt %.
20 . The alloy of claim 11 , further comprising Mn present at a level of about 0.2 wt % to about 0.6 wt %.Join the waitlist — get patent alerts
