Thank you for your question. Our faucets are made of several materials, and may depend on which model they are asking about. For example, the 559HA-DST's metal components: The top cap is bronze or 36000 brass, the bonnet nut is 36000 brass, the undercover plate is either stainless steel or 260 brass,the escutcheon is zinc.
We can't provide that level of detail every time. And specific amounts are considered proprietary (trade secret).
But in general, the faucet may contain:
Brass (36000, 260) (hub, handle, body, tube, fittings)
Zinc (escutcheon, hub, handle)
Stainless Steel (undercover plate, seat liner, set screw)
PEX-C (puck and tubing)
Synthetic rubber - EDPM, Santoprene (hoses)
