01 / What We Fabricate
Phosphor Bronze Stamping Services for Custom OEM Parts
This product page owns the commercial phosphor bronze stamping and supplier quotation scope for finished springs, clips, terminals and precision parts. The related DFM article covers coil, grain, burr and tooling decisions, while the bronze material page compares alloy families; neither replaces the manufacturing RFQ.
Clips and Terminals
Stamped retention and electrical terminal parts with controlled forming and plating zones.
Shield Fingers
Repeat conductive spring fingers and grounding clips for electronic assemblies.
Washers and Precision Plates
Flat or lightly formed bronze spacers, washers and small plates with lot identity.
Our scope: released phosphor bronze stampings
DRAmetal manufactures and inspects the released stamped part. The OEM owns electrical rating, contact-force targets, fatigue life, plating-system suitability, mating design and final assembly validation.
02 / Bronze Stamping Types
Contact Springs, Clips, Shield Fingers and Washers
The OEM defines electrical, mechanical and life-cycle requirements; DRAmetal controls the released stamped geometry and records.

04 / Manufacturing Process
From Strip Specification to Protected Stamped Parts
01
Function Boundary
Confirm released electrical, spring, retention and mating requirements.
02
Material Review
Lock alloy, temper, thickness, grain and finish or plating requirements.
03
Tooling Study
Review pitch, carrier, burr direction, form sequence, springback and tool access.
04
Tool Tryout
Validate blank, forms, restrike features and part removal without deformation.
05
First Article
Report drawing CTQs and approved functional measurements against tool revision.
06
Production and Packout
Maintain strip lot and protect spring forms from nesting or damage.
05 / Why It Matters
Why Bronze Stampings Depend on Material and Burr Control
Parts with the same outline can behave differently when temper, grain, burr or plating changes.
Temper Variation
Spring behavior depends on the exact released material condition.
Burr Direction
Burr orientation can affect mating, wear and electrical contact interfaces.
Form Springback
Tool compensation must remain tied to alloy, temper and strip direction.
Packout Deformation
Fine contacts and shield fingers require protected handling after stamping.

Why OEMs Use DRAmetal for Phosphor Bronze Stampings
01
Material-lot control
Alloy, temper and strip identity remain connected to production records.
02
Tooling progression
Prototype parts can inform compound or progressive die release.
03
Functional CTQ mapping
Spring profile, burr and mating geometry drive inspection.
04
Protected packout
Part orientation and packaging can be defined to prevent form damage.

09 / FAQ
Phosphor Bronze Stampings FAQ
What phosphor bronze stamped parts do you manufacture?
We manufacture build-to-print contact springs, clips, terminals, shield fingers, washers, shims and small formed parts.
How do I request custom phosphor bronze stamping?
Send the part drawing, phosphor bronze alloy and temper, strip thickness, grain and burr direction, annual volume, tooling ownership, plating or finish zones, inspection requirements and order quantity. The manufacturing route is confirmed against the released project requirements.
Can alloy and temper be lot traced?
Yes. Material identity and supplier records can be maintained against the production lot according to the agreed quality plan.
Can you control burr direction?
Yes. Burr direction should be specified relative to the mating or contact surface and considered in the strip and die layout.
Do you validate electrical contact life?
No. The OEM owns contact-force, electrical, wear and life-cycle validation. We control the released geometry and material records.
What should a phosphor bronze stamping RFQ include?
Send drawings, alloy and temper, strip thickness, grain and burr direction, annual volume, tooling plan, finish or plating requirements, CTQs and quantities.
