Silver provides the best electrical conductivity of all metals. It is an order of magnitude less expensive than gold, but it has a tendency to tarnish (oxidize). It is often used in low-loss waveguide components. The silver oxide layer is typically less than a skin depth so it has little effect on electrical loss. Silver pastes are often used in LTCC products in place of more expensive gold conductors.
