This silver-plated brass contact pin is made of high-quality H62/H59 brass and adopts a high-standard high-density silver plating process (the thickness of the plating can be customized, ranging from 3-5 microns), which combines high-strength mechanical properties with industry-leading electrical conductivity. After precision turning and centerless grinding, the dimensional tolerance can reach ±0.005~±0.01 mm. The surface is mirror-polished, smooth and burr-free, ensuring smooth insertion and removal without damaging the mating parts. In terms of core performance, silver plating enables ultra-low contact resistance in the milliohm range, minimizing losses in signal and current transmission. At the same time, it also has excellent corrosion resistance and oxidation resistance, will not blacken or corrode after long-term use, and can adapt to a wide temperature range of -40°C. ℃ ~+125 ℃. The pairing life is more than 500 times, and it can maintain a stable connection even if it is used repeatedly. This pin is widely used in electronic connectors, wiring harnesses, automation equipment, automotive electronics, precision instruments and other fields. It supports full-dimensional customization of diameter, length, coating thickness and other parameters, and rapid prototyping of non-standard parts. Strictly compliant with RoHS and ISO standards, regular specifications will be shipped within 3-7 days, and customized orders will be shipped within 7-15 days. Bulk purchasing, stepped discounts; full quality inspection, factory pass rate ≥99.9%, providing stable and reliable core guarantee for your electrical connection needs.
