Bronze Precision Machined Component

Bronze precision part is the catch-all listing for bronze components that don't fit the standard form factors, bushing, contact finger, ring, commutator plate. If you have a drawing for a bronze geometry that's specific to your switchgear or assembly design, this is the right starting point.

Custom bronze parts cover a wide range of MV switchgear applications: spring carriers, terminal blocks, conductor adapters, mounting brackets that need bronze's conductivity and corrosion resistance, and the dozens of small machined parts in any modern switchgear assembly.

Applications

• Custom bronze geometries for MV switchgear OEMs with proprietary designs
• Replacement parts where the original SKU isn't cataloged and only the drawing or sample exists
• Specialized bronze components for non-standard switchgear applications
• One-off bronze parts for prototyping and engineering samples

Technical Notes

Bronze machining is CNC-friendly with carbide tooling. The alloys behave differently, phosphor bronze cuts cleanly, aluminum bronze is harder and slower, brass is the easiest to machine. Tolerance achievable depends on the alloy and the part complexity; standard machining tolerance covers most switchgear applications, with tighter tolerance possible for critical features.

For complex parts, we offer a design-for-manufacturability review before tooling. Submit your drawing and we'll flag any features that would benefit from a small geometry change, usually saving cost and improving yield. There's no obligation if you'd prefer to machine the drawing as-is.

For prototypes, single-piece orders are routine but disproportionately expensive per part compared to small-batch runs. If you're prototyping with intent to move to production, ordering a small batch (e.g. 10–20 pieces) is often more cost-effective.

Sourcing & OEM

Send drawings in DXF / PDF / STEP format with target quantity and alloy preference. We'll confirm feasibility, recommend any geometry tweaks, and quote.
