青铜触指

Phosphor bronze (C51000, C52400) for spring duty, repeated flexing, plug-and-unplug action. Aluminum bronze (C95400) for sliding wear duty, disconnector contacts, isolator fingers. For new designs, send your duty cycle and we can recommend.

The CuW Contact Finger handles arc duty (making and breaking under load). The CuW tip resists arc erosion. Bronze contact fingers handle sliding or spring-action duty without arc: lower cost, no CuW tip, and the bronze alloy serves both spring and conduction.

Not by default, bronze fingers ship as machined. Silver plating on the contact face is available for low-resistance applications; specify thickness in your order.

Yes. Most legacy refurbishment orders work from the original drawing or a sample. Send what you have with your inquiry.
