Bronze: Bearings Versus Spring Strip

Bronze covers multiple copper-alloy families and product forms. A bearing bronze and a phosphor-bronze contact strip answer different manufacturing questions. Material reference.

Bearings Versus Spring Strip

For sliding contact, start with C93200 or C95400 and the complete lubrication and load case. For a spring contact, investigate C51000, C51900 or C52100 with the required temper and plating. Do not compare these options on a single generic bronze property table.

Manufacturing and acceptance checks

Provide either the bearing's shaft, speed and lubricant details or the contact's force, deflection and electrical requirements. Request a complete alloy designation and relevant product specification. Compare finished-part acceptance and processing cost alongside stock price before selecting the material.
