Product Description

1. Description
 
Copper-Nickel-Zinc alloy, also called nickel silver, German silver, new silver, nickel brass, albata, or electrum, is a copper alloy with nickel and often zinc. Nickel silver is named for its silvery appearance, but it contains no elemental silver unless plated.
