Electrical Contact Stamping
Hole Position Accuracy : ≤0.1 mm
Minimum Order Quantity : 200 pcs
Weight Range : 0.5g–500kg
Electrical contact stamping parts are manufactured using high-precision stamping technology, and the accuracy of key dimensions is strictly controlled within ±0.01 mm to ensure the consistency of contact geometry and fit reliability. Its surface has been finely processed, and the average roughness is stably maintained below 1 micron, providing an ideal basis for low and stable contact resistance. These precision components are widely used in demanding connector and switch fields.
To meet the long-term performance requirements of harsh environments, these electrical contact stampings undergo special surface treatment and protection, successfully passing a 96-hour salt spray test and demonstrating excellent corrosion resistance. The material selection, manufacturing process, and final performance all adhere strictly to relevant German industrial standards, ensuring the product reaches internationally leading levels in electrical performance, mechanical strength, and environmental adaptability, providing a durable and reliable electrical connection solution for a variety of critical electronic devices.

Features
Electrical contact stampings feature high-precision geometric contours and a uniformly smooth surface. Plating layers such as gold, silver, and tin determine both visual character and protective performance.
Component hardness ranges from ductile to ultra-hard (up to 400 HV), with sharp, flawless edges. High-hardness areas effectively resist wear during insertion and removal, ensuring stable contact morphology and providing a reliable physical barrier for electrical connections.

►Electrical contact stampings exhibit high-precision geometric contours in appearance, and the surface usually presents a uniform and consistent finish or specific functional textures. Its color mainly depends on the selected surface plating. Common ones are bright silver (silver plating), golden yellow (gold plating) or grayish white (tin, nickel plating), which not only provides visual identification, but is also directly related to its protection level. These components have a wide range of hardness, from a softer ductile state to a very hard rigid state through material selection and heat treatment process to meet the requirements of different applications for contact deformation resistance.
►Visually, high-quality stamping parts have clear and sharp edges without burrs, and the surface color is uniform without spots or color differences. The plating gives it a unique metallic luster, such as the gorgeous feeling of gold plating or the cool feeling of silver plating, while the matte treatment presents a delicate low-reflective effect. In terms of hardness, its performance is significantly higher than that of ordinary stamped metal parts, especially in critical contact areas. The high hardness (up to 400HV or above) effectively resists plug-in wear and permanent deformation, ensuring the stability of contact shape and contact pressure during long-term use. It is an important physical guarantee for reliable electrical connection.
Combination Matching
Common Matching
-
Spring components
Provide constant contact pressure, compensating for mating wear and tolerance fluctuations, commonly found in battery contacts or connectors.
-
Metal housings/shields
Provide mechanical protection and electromagnetic shielding, used in high-frequency connectors or industrial interfaces.
-
Fasteners
Provide physical attachment to PCBs or cables, ensuring connection reliability in high-vibration environments.
Applications

New Energy Vehicle Charging Connector Contacts
Beryllium copper stamped pins with 0.01mm precision can carry 200 amperes of current, and their surface is silver-plated to reduce contact resistance.
The IP67 sealing structure resists moisture corrosion, ensuring that charging efficiency does not decrease after tens of thousands of plugging and unplugging cycles, meeting the safety requirements of fast charging.
5G Base Station High-Frequency Connectors
Phosphor bronze stamped arrays transmit 40 GHz signals without loss. Gold plating minimizes signal reflection.
Compact layouts accommodate millimeter-wave frequencies. Anti-vibration configurations ensure stable base station operation for ten years.


Medical Monitor Electrode Interfaces
Stainless steel stamped contacts retain 1 milliohm resistance with biocompatible plating.
