The Conductive Parts Of The Cable Terminals Are Designed With Phosphor Bronze Electroplated Matte Tin.

Phosphor bronze was chosen as the base metal material for part wire lugs due to its suitable mechanical strength and fatigue resistance for long-term, repetitive connection applications. Teal plating forms a thin, uniform tin film on the phosphor bronze surface, contributing to interface consistency. This combination demonstrates good controllability in the production process.

Phosphor bronze parts are pre-formed into parts electrical lugs through mechanical stamping or milling, followed by cleaning, activation, and tin plating. Teal plating employs a low-current-density tin plating process, resulting in a fine tin layer roughness, which helps reduce oxide film formation. After final cleaning and drying, part terminal lugs undergoes quality control to measure tin layer thickness and adhesion. This chain process provides valuable insights for controlling the conductivity of part copper lugs and improving long-term reliability.
