I've also used the fin(s) out of old copper heat sinks for these as well 
as for the "hairpin" parasitic suppressors.
it's easy to cut with a pair of hears. NOTE many metal shears will leave 
a rough or serrated edge while a good pair of scissors will leave a nice 
clean edge.
These are easy to bend, easy to punch or drill holes (use a high speed 
so the drill doesn't catch, but *be careful*) and hold their shape well.
some of the newer ones are copper plated Aluminum and nearly all current 
models are Aluminum with some being very large. If those were copper the 
motherboards probably wouldn't support them.  They just barely fit into 
most full size tower cases.
