what metal is mixed with silver to make sterling silver

Sterling silver is made by mixing pure silver with another metal, most commonly copper.

What metal is added?

  • Standard sterling silver is 92.5% pure silver and 7.5% copper by weight.
  • Other metals like zinc or tin are sometimes used in small amounts, but copper remains the typical main additive.

Why copper is used

  • Copper makes soft pure silver harder and more durable, so jewelry and cutlery resist bending and wear better.
  • The silver–copper mix keeps a bright, attractive shine while being strong enough for everyday use.

Extra note on “925”

  • The “925” or “.925” stamp means the alloy is 92.5% silver and 7.5% other metals, usually copper, which is the standard for sterling silver.
