Aluminum coated steel wire is commonly used for electric fences. 
Although proper practice is to install it with low tension (as per 
vendor and MFG) that is not because of any failing in the wire's 
strength or resilience. It can take significant tension and last a good 
long time.  One issue is the skin effect.  Your lowest frequency of 
interest will penetrate into the wire to the greatest depth. You will 
get better performance if your skin depth does not exceed the thickness 
of the aluminum outer layer.  I cant quote the formula for skin depth 
from memory but it is readily available.

There has been a lot of this aluminum coated steel wire used for 
antennas with good success.
