Description
Phosphor Bronze Electrical Contact Strip is a precision-stamped conductive component designed for reliable electrical connections. Manufactured from high-quality phosphor bronze, it offers excellent electrical conductivity, high elasticity, and superior fatigue resistance, ensuring stable contact performance over repeated mating cycles.
This contact strip features strong spring force, low contact resistance, and good corrosion resistance, making it ideal for long-term use in demanding electrical and electronic applications. It can be supplied with various surface finishes such as tin, nickel, silver, or gold plating to improve solderability, wear resistance, and service life.
Widely used in connectors, PCB assemblies, sockets, battery contacts, and automotive electronics, phosphor bronze electrical contact strips are suitable for both manual and automated assembly. Custom designs, thicknesses, and shapes are available to meet specific application requirements. OEM and ODM services are supported.

1. Consistent and Stable Product Quality
We apply standardized production processes and strict tooling control to ensure stamped metal parts maintain stable quality across different batches.
2. High Precision Tolerance Control
Through optimized die design and springback compensation, we consistently meet tight dimensional tolerances required for reliable assembly and fit.
3. Clear Material Specification and Traceability
All products are manufactured strictly according to specified materials such as H62 brass. Incoming material inspection and batch traceability prevent material mismatch issues.
4. Effective Burr and Edge Control
Optimized die clearance, regular tool maintenance, and deburring processes ensure smooth edges, improved safety, and reduced secondary processing costs.
5. Reliable Surface Finishing Quality
We offer tin, nickel, and silver plating with controlled pretreatment and plating parameters to ensure strong adhesion, uniform thickness, and corrosion resistance.
Q1: What are common quality issues in stamped brass contacts?
Common issues include burrs, dimensional deviation, surface scratches, and inconsistent spring force. These are typically caused by improper die clearance, tool wear, or unstable material properties.
Q2: How are burrs controlled in stamped brass contacts?
Burrs are minimized by optimizing stamping die clearance, maintaining sharp tooling, and using secondary deburring processes such as tumbling or vibratory finishing.
Q3: Why do stamped contacts sometimes have dimensional variation?
Dimensional variation is often related to material springback, die wear, or forming stress. Precision progressive dies and in-process inspections help ensure stable tolerances.
Q4: How is spring performance ensured in brass contacts?
Spring performance depends on material selection, thickness control, and forming design. Fatigue testing and insertion cycle tests are conducted to verify long-term reliability.
