Tingfeng Hardware provides phosphor bronze stamped battery contacts, specifically designed for battery connections in portable electronic devices. Using high-conductivity phosphor bronze (C5191) material, we produce low contact resistance, high-elasticity battery contacts and connector tabs through precision stamping and bending forming. Gold or nickel plating ensures long-term oxidation resistance and stable conduction. With 16 years of precision manufacturing experience, we provide reliable battery connection solutions for consumer electronics and wearable devices.
Product Description
Phosphor bronze stamped battery contacts are critical components for reliable battery-to-PCB connections in portable electronic devices. Our contacts use phosphor bronze (C5191) material, offering excellent conductivity (approximately 15% IACS), fatigue resistance, and elastic memory. Through precision stamping forming, contacts achieve stable spring force, ensuring reliable contact across varying battery heights. Gold or nickel plating controls contact resistance below 10mΩ while ensuring solderability. Each contact undergoes 100% force testing and dimensional inspection, suitable for compact space applications such as TWS earbuds, smartwatches, and portable medical devices.
