Nickle silver alloys possess excellent strength and corrosion resistance as well as high thermal and electrical conductivity. Although it is named because of its silver color, it does not contain silver.

Due to its electrical properties, it is often used in anodes, fuel cells and battery casings. But one of the most common applications is to extrude nickel silver into elevator sills and the hardware used in elevators and other architectural applications. Its corrosion resistance also makes it
well suited for plumbing fixtures. 

Two of the most important mechanical properties are described below.

The tensile strength of a material is a measure of the amount of stress it can withstand while being pulled before it will break.

For the sake of comparison, the table below shows the tensile strength of two popular nickel silver alloys.

The yield strength of an alloy is defined as the point at which it begins to deform. It’s an indication of the limit of the alloy’s elastic behavior. Stretch it and it changes shape. Remove the stress and it returns to its original shape. At some point, it breaks.
