792 Nickel Silver Product Guide
Applications | Specifications | Mechanical and Chemical Data | Tolerances
Overview
Nickel Silver is neither nickel, nor silver, it’s mostly copper and zinc, though with some nickel alloyed as well. It’s also often called German Silver for historical reasons, but again, it’s not silver, and was not discovered by Germans. 792 nickel silver has good strength, a silvery appearance, and excellent resistance to corrosion and tarnish. It is typically used for decorative and ornamental applications. 792 has exceptional solderability and good electrical conductivity. The main difference between the 770 and 792, is that the 770 is almost exclusively used in sheet whereas 792 is often used in round bars.
