description

Copper plated terminals provide the solderability and electrical conductivity of copper with the mechanical strength of steel underneath. The copper layer solders easily - making these the standard choice for electrical connections where the terminal must be soldered to a wire or PCB. Without copper plating, soldering to steel is difficult and unreliable. The copper layer is typically 3 to 15 micrometers thick - enough to provide good solderability and electrical conductivity without adding significant cost. Thicker copper provides better corrosion resistance for outdoor applications.

Copper Plated vs. Silver Plated

Copper plating: better solderability, lower cost, the standard for general electrical connections. Silver plating: better conductivity, does not oxidize as quickly, preferred for high-frequency RF applications and premium electrical connections.

FAQ

Q1: MOQ?

Quality is non-negotiable in precision manufacturing. Every component undergoes rigorous inspection at each stage of production.

ISO 9001:2015 - Certified quality management system covering design, machining, and inspection
Passivation / Electropolishing - ASTM A967 procedures for corrosion resistance
Material Traceability - Heat number tracking from raw material to finished part
First Article Inspection (FAI) - Full dimensional report included with every new order

From raw material to finished product, every step is controlled and documented:

Material Preparation - CNC turning/milling to near-net shape
Heat Treatment - Through-hardening or case-hardening for strength-critical parts
Surface Preparation - Degreasing, acid cleaning, and surface activation
Electroplating - Controlled bath process with thickness monitoring
Sealing / Baking - Chrome sealing, anodize sealing, or hydrogen embrittlement relief baking
Inspection - Coating thickness measurement, adhesion testing, and visual check
Packaging - Protective interleaving, VCI packaging, and anti-tarnish wrapping
