What is claimed is: 
     
         1 . A titanium alloy comprising:
 about 5 to about 33 percent by weight copper;   about 1 to about 8 percent by weight iron; and   balance titanium and impurities.   
     
     
         2 . The titanium alloy of  claim 1  wherein said copper is present at about 13 to about 33 percent by weight. 
     
     
         3 . The titanium alloy of  claim 1  wherein said copper is present at about 15 to about 30 percent by weight. 
     
     
         4 . The titanium alloy of  claim 1  wherein said copper is present at about 17 to about 25 percent by weight. 
     
     
         5 . The titanium alloy of  claim 1  wherein said copper is present at about 18 to about 22 percent by weight. 
     
     
         6 . The titanium alloy of  claim 1  wherein said iron is present at about 2 to about 7 percent by weight. 
     
     
         7 . The titanium alloy of  claim 1  wherein said iron is present at about 3 to about 6 percent by weight. 
     
     
         8 . The titanium alloy of  claim 1  wherein said iron is present at about 3 to about 5 percent by weight. 
     
     
         9 . The titanium alloy of  claim 1  wherein said iron is present at about 4 percent by weight. 
     
     
         10 . The titanium alloy of  claim 1  wherein:
 said copper is present at about 13 to about 33 percent by weight, and 
 said iron is present at about 3 to about 6 percent by weight. 
 
     
     
         11 . The titanium alloy of  claim 1  wherein:
 said copper is present at about 15 to about 30 percent by weight, and 
 said iron is present at about 3 to about 5 percent by weight. 
 
     
     
         12 . The titanium alloy of  claim 1  wherein:
 said copper is present at about 17 to about 25 percent by weight, and 
 said iron is present at about 3 to about 5 percent by weight. 
 
     
     
         13 . The titanium alloy of  claim 1  wherein oxygen is present as an impurity at a concentration of at most about 0.25 percent by weight. 
     
     
         14 . The titanium alloy of  claim 1  wherein nitrogen is present as an impurity at a concentration of at most about 0.03 percent by weight. 
     
     
         15 . The titanium alloy of  claim 1  consisting of said copper, said iron and said titanium. 
     
     
         16 . The titanium alloy of  claim 1  having a solidus temperature and a liquidus temperature, wherein a difference between said solidus temperature and said liquidus temperature is at least 50° C. 
     
     
         17 . The titanium alloy of  claim 1  having a solidus temperature and a liquidus temperature, wherein a difference between said solidus temperature and said liquidus temperature is at least 50° C. 
     
     
         18 . The titanium alloy of  claim 1  having a solidus temperature and a liquidus temperature, wherein a difference between said solidus temperature and said liquidus temperature is at least 100° C. 
     
     
         19 . The titanium alloy of  claim 1  having a solidus temperature and a liquidus temperature, wherein a difference between said solidus temperature and said liquidus temperature is at least 150° C. 
     
     
         20 . The titanium alloy of  claim 1  having a solidus temperature and a liquidus temperature, wherein a difference between said solidus temperature and said liquidus temperature is at least 200° C.
