Description
Atomfair 304 Stainless Steel Wave Spring (Belleville Washer) and Matching Accessory Series
1. Core Technical Parameters
The core product is a wave spring (Belleville washer), compatible with CR2032 and other button battery models, with key dimensional parameters: diameter 15.4mm * height 1.2mm * thickness 0.25mm, and the dimensional tolerance complies with precision mechanical component standards. Manufactured from 304 stainless steel (304ss), the material meets ASTM A240 specifications, featuring high mechanical strength (tensile strength =515MPa) and excellent corrosion resistance, suitable for various environmental working conditions. The product is packaged in anti-static vacuum-sealed bags with 100 pieces per bag to ensure performance stability during storage and transportation.
The supporting accessory system is complete, covering conical springs, multi-specification precision gaskets for button batteries, and a full range of battery holders. The material system includes options such as 304 stainless steel/316 stainless steel (316ss, with better corrosion resistance), 99.9% high-purity aluminum, and gold-plated (plating thickness 0.5um-2um), which can meet the requirements of different electrochemical environments, conductive performance and assembly precision in scientific research scenarios.
2. Core Functions and Scientific Research Application Scenarios
This series of products is specially designed for precision scientific research scenarios of button battery power supply systems, with three core functions:
-
Elastic Buffering: Through the precise deformation of the wave structure, vibration compensation is realized (elastic force fluctuation =5% when compression is 0.3mm-0.8mm), protecting the battery and electrode components from mechanical damage.
-
Stable Contact: The optimized structural design ensures a surface contact rate of =95% between the spring and the battery electrode, ensuring stable conductive transmission and avoiding contact failure caused by poor contact.
-
Multi-environment Adaptation: The material’s corrosion resistance and temperature adaptability can meet the test requirements of extreme environments (-40℃-85℃, relative humidity 95%), ensuring the reliability of experimental data.
It has a wide range of scientific research application scenarios and is suitable for experimental device and prototype development in the following fields:
-
Electronic device R&D: Assembly of power supply modules for micro sensor nodes and portable detection equipment.
-
Smart hardware prototyping: Debugging of battery contact systems for wearable devices and IoT terminals.
-
Industrial control modules: Verification of power supply reliability under extreme environments.
The product can meet the needs of the entire scientific research process, including rapid assembly of prototypes, long-term reliability tests (fatigue life =10000 compression cycles), and multi-material compatibility tests, providing core hardware support for the accuracy and repeatability of experimental data.
