Due to the fact pure silver may be very delicate, most silver useful for these functions is alloyed with copper, with finenesses of 925/a thousand, 835/a thousand, and 800/a thousand remaining common. One disadvantage is the straightforward tarnishing of silver in the existence of hydrogen sulfide and its derivatives. Which includes valuable metals including palladium, platinum, and gold offers resistance to tarnishing but is fairly costly; foundation metals like zinc, cadmium, silicon, and germanium usually do not fully prevent corrosion and have a tendency to have an impact on the lustre and colour on the alloy.

Various hues of silver–copper–gold alloys Silver varieties alloys with most other aspects within the periodic table.

Silver is beneficial in the manufacture of chemical devices on account of its reduced chemical reactivity, significant thermal conductivity, and becoming conveniently workable. Silver crucibles (alloyed with 0.15% nickel to prevent recrystallisation in the metal at purple heat) are utilized for finishing up alkaline fusion.
