Phosphor Bronze Wire for Custom Springs & Custom Wire Forms
Please note that we do not sell phosphor bronze or any other materials in raw form. Phosphor bronze wire is a material option for custom springs, etc., manufactured by Peninsula Spring.
Phosphor bronze wire exhibits good physical properties and fair electrical conductivity. Round, square, flat, and special-shaped phosphor bronze wire is ideal for custom springs and custom wire forms, as well as electrical contacts and connectors. The material is also a popular, lower-cost alternative to Beryllium copper for many applications.
To discuss material requirements for your custom manufacturing project, contact Peninsula Spring today.

Heat Treating Phosphor Bronze
This material is delivered in pre-tempered condition, and no further hardening can be obtained via heat treating. However, depending on your application, completed phosphor bronze springs and wire forms will undergo a stress-relieving process.
Manufacturing Custom Phosphor Bronze Springs & Wire Forms
Phosphor bronze is cold worked to the required temper. This material is extremely well-suited to spring and wire form applications that require corrosion resistance and/or electrical conductivity.
