Brass stamping parts:The precision manufacturing and reliable connection solutions in the new energy era
Feb 11, 2025
Brass material properties: Why is it the first choice in the new energy field?
Both electrical conductivity and economy:
The conductivity of Silver Plated Brass Terminal is 15-30MS/m (the lower the zinc content, the better the conductivity), and the cost is only 60%-70% of that of phosphor bronze, meeting the needs of large-scale commercialization.
Excellent mechanical properties:
The tensile strength is 370-500MPa, the elongation is ≥20%, and it can withstand harsh working conditions such as high-frequency plugging and unplugging, vibration.
Environmental tolerance:
Electrical Brass Switch Socket Part has passed the 720-hour neutral salt spray test (ASTM B117), is resistant to weak acids, alkalis and humid environments, and has a service life of more than 10 years.

The secret of brass stamping parts manufacturing process
1. PRECISION STAMPING CORE TECHNOLOGY
High-speed progressive die technology:
Multi-station continuous stamping (800-1200 times/minute), achieving one-time molding of complex structures with a tolerance of ±0.02mm.
Breakthrough in ultra-thin processing:
The hydraulic-mechanical composite stamping process is used to support the processing of 0.1mm ultra-thin plates to avoid deformation and cracking.
Surface treatment process:
Plating scheme: nickel plating (corrosion resistance), gold plating (high conductivity), tin plating (weldability optimization);
Environmentally friendly passivation: chromium-free passivation technology, compliant with RoHS standards.
2. FULL-PROCESS QUALITY CONTROL SYSTEM
Material testing:
XRF spectrometer ensures that the proportional deviation of Electrical Brass Press Parts For Switch SocketD is ≤0.3%;
Online quality inspection:
Real-time detection of burrs and cracks, the yield rate of Brass Sheet Metal Parts Terminal is ≥99.95%;
Performance test:
On-resistance test (<5mΩ), plug-in life test (≥500,000 times).

Selection guide: How to match the needs of new energy equipment?
Conductive scenes (such as battery connectors):
Silver Plated Brass Terminal made of H62/H65 low zinc brass (conductivity >25MS/m) is preferred, with silver or gold plating on the surface.
Corrosion-resistant scenarios (such as outdoor equipment):
Brass Sheet Metal Stamping should choose H59 high zinc brass + environmentally friendly chromium-free passivation, or nickel plating + sealing treatment.
Structural load-bearing scenarios (such as bracket components):
Electrical Brass Switch Socket Part should be made of cold-rolled reinforced brass (hardness ≥120HV) and designed with reinforcing ribs.
