This is 1 2605131s210f6, a stamped terminal and contact part produced by BQUQ in Dongguan, China. It is a high-precision electrical contact component designed for reliable current transfer in connectors, relays, and switch assemblies. You get a consistent flatness of 0.02mm, a burr height under 0.05mm, and a surface finish of Ra 0.8µm, all at a hardness of 40-45 HRC, which ensures long cycle life under repeated mating and unmating.
Stamping thin metal at high speed creates micro-bending and spring-back. We compensate for this with a progressive die that uses a 5-stage forming sequence, not a single hit. Each stage is optically measured before production starts. The result is a positional tolerance of ±0.01mm on the contact beam and a terminal width that stays within ±0.015mm across a 10,000-piece run. We run the press at 150 strokes per minute, but we slow it to 80 for the final calibration pass on critical dimensions.
For 1 2605131s210f6, we offer two standard materials. C5210 phosphor bronze gives you 590 MPa tensile strength and excellent fatigue resistance—ideal for spring contacts that see 100,000+ cycles. Beryllium copper C172 is optional when you need higher conductivity (22% IACS) and a hardness up to 45 HRC after heat treatment. Both materials come with a mill certificate that confirms chemical composition and grain size, traceable back to the coil batch number.
We age-harden C172 in a vacuum furnace at 315°C for 2.5 hours to reach 40-45 HRC. This is not a surface case—the hardness is through the entire 0.4mm thickness. The process eliminates internal stress, so the terminal does not distort when you crimp it onto a wire. For C5210, we use a stress-relief anneal at 200°C for 1 hour, which improves spring-back consistency and keeps the hardness at 90-100 HRB, matching the original spec for high-cycle applications.
As-stamped, 1 2605131s210f6 has a surface finish of Ra 0.8µm on the contact area, which reduces electrical resistance and prevents micro-arcing. If you need plating, we offer selective gold plating (0.76µm thick) only on the contact tip, leaving the base metal for solderability. The plating adhesion is tested with a 90° bend test on every 500th piece. We also provide tin plating (2-5µm) for lower-cost applications that require corrosion resistance.
Every lot of 1 2605131s210f6 is inspected under a 40x optical comparator before packing. We check five parameters: terminal width, contact gap, burr height, surface finish, and plating thickness. A sample of 32 pieces from each 10,000-piece lot goes through a digital micrometer and a profilometer. If any piece fails, the entire lot is quarantined and re-run. We issue an inspection report with actual measurements, not just a pass/fail stamp.

That means we skip the 10-day die-making wait. Once you approve the sample, we run your order on a 25-ton high-speed press that is already set up for this part number. A typical 50,000-piece order takes 4 hours of press time and 1 day of inspection. From drawing approval to your door in Dongguan for local pickup, that is 5 days. For export, add 2-3 days for freight consolidation.
There is no MOQ—you can order 1 piece for a prototype test or 1 million pieces for production, and the unit price will reflect the volume break.
Yes, we can switch to C172 beryllium copper or add selective gold plating, but any material change requires a 24-hour re-qualification of the die and a new sample for your approval before mass production.
We use a five-point inspection on every lot, including optical comparator and profilometer checks, and we send you a measurement report with actual values for each batch—not a generic certificate.
If you need a new tool, we deliver a working progressive die in 10-15 days and first articles in 3 days after that; for the existing 1 2605131s210f6 die, standard lead time is 5 days.
This part is made in China at our Dongguan factory, where we have 20 years of experience in precision manufacturing for automotive and industrial connectors. For prototypes or short runs, compare our stamping process with the metal stamping vs CNC machining for prototypes breakdown to see which fits your timeline. If you are designing the mating housing, the CNC cutting tool selection guide for secondary operations is relevant, and for surface finishes beyond Ra 0.8µm, check the CNC machining tolerances guide for plating and passivation options.
Send your drawing or the part number 1 2605131s210f6 to sc@bquq.com, and we will return a firm quote within 12 hours—including die amortization if you need a custom version. For immediate questions, WhatsApp +86 13713157787. No MOQ, no minimum callout, just a precise price for your exact quantity.
