Wire Bending & Shaping

Hi, i am looking for some guidance possible from all you jewellery workers out there, regaring wire bending and shaping. I am planning making some kinetic sculptures (posh mobiles) which need some decent / attractive wire supports. Currently i am thinking of using half hard, 18 gauge stainless steel has anybody had experience with this material and its malleability? Or could suggest a possible suitable alternative which is workable, attractive and tarnish free. Thanks in anticipation.
