Platinum-clad strip and wire are used in electrical contacts, thermocouple sheaths, and chemical-process equipment where platinum's corrosion resistance and catalytic stability are needed but solid platinum would be cost-prohibitive. The cladding process bonds a thin platinum layer to a less expensive substrate, delivering surface performance at lower material cost.

Once platinum-clad material is fabricated into a finished article — such as a stamped electrical contact or a formed laboratory vessel — it generally moves to the heading covering that finished article rather than remaining in 7111. The 'not further worked than semimanufactured' condition is the key boundary; consult a customs broker or seek a binding ruling for finished components.
