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.

Aluminum fence wire stretches easily under load. It needs to be
supported every ten feet or so, not ideal for long wire antennas. I
won't even use it for electric fences ;-)

I think I'll pick up some aluminum fence wire at Lowes tonight on the
way home from work.
