Charging electrical contact

stampedcopper alloycopper

Overview
This precision stamped copper contact terminal provides low contact resistance and consistent mechanical geometry for reliable electrical connections in connectors and charging interfaces. Designed for high-volume electronic assemblies, it delivers repeatable contact performance through controlled stamping and forming processes.

Material / Surface / Tolerance / Application
Material: Copper / Copper alloy
Surface: Copper plated / Tin plated (optional)
Tolerance: ±0.01 mm
Application: Electrical contact and conductive connection in connectors, charging interfaces, and electronic components

Product Description
The copper substrate offers excellent electrical conductivity and thermal performance. Optional plating (copper or tin) enhances corrosion resistance and service life. The compact stamped geometry eases integration into connector housings and charging interfaces while maintaining reliable mating and contact retention.

Manufacturing Process
Produced by precision stamping and forming from high-grade copper or copper alloy, followed by optional surface plating. Each batch undergoes dimensional inspection to verify compliance with tolerance requirements prior to final packaging and delivery.
