Description
Custom Battery Contact Shrapnel – Phosphor Bronze Stamping
Tingfeng Hardware provides custom battery contact shrapnel specifically for CR2032 and coin cell holders, manufactured from phosphor bronze (C5191) through precision progressive die stamping and bending forming processes.
Product Overview
The CR2032 coin cell battery contact shrapnel is the core conductive component of PCB-mounted battery holders, responsible for stable power transmission from the battery to the circuit. Our shrapnel is stamped from phosphor bronze (C5191), with a dimple design on the positive contact surface ensuring reliable contact with the battery positive terminal, and a negative contact arm providing stable compression force (1.0-2.0N) to accommodate different battery thicknesses.
Nickel plating ensures solderability and oxidation resistance. Each contact undergoes 100% force testing and dimensional inspection, ensuring stable electrical performance throughout battery insertion and replacement cycles.
