Flexible circuit options include polyester (PET) that uses silver ink as the circuit element, and flexible PCB (FPC) that uses copper as the conductive element. Form, fit, and function is very similar for both though their respective costs and reliability can drastically differ.
Most people are aware of how excellent copper is as a conductor of electricity. That’s why copper is frequently used in wires, circuit boards, etc. The flexible circuit membrane switches make no difference.
If there is a concern with resistance, such as your max circuit resistance needs to be 200Ω or less, you may want to consider a polyimide circuit versus a PET circuit. Just as in a bulk cables’ conductor, the circuit resistance of a membrane switch is a function of the trace cross section, material, and length.
