Description
Product Overview
The Atomfair Gold-plated Stainless Steel Wave Spring is a precision-engineered elastic component exclusively designed for CR2032 button battery boxes. This Wave Spring features strict dimensional specifications: 15.4mm diameter × (1.2±0.03) mm height × 0.2mm thickness, with a lightweight design of just 0.1 ounce per unit. As a core button battery (扣电) accessory, the Wave Spring delivers ultra-high dimensional accuracy and robust elastic stability, ensuring a perfect fit for internal battery assembly and long-term reliable performance. What distinguishes this Wave Spring is its seamless integration with CR2032 battery boxes, making it an indispensable component for precision electronic applications.
Material & Craftsmanship Advantages
Dual-performance Coating Treatment
The Wave Spring is manufactured using high-quality stainless steel as the base material, enhanced by a uniform gold-plated finish that endows the Wave Spring with two core functional advantages:
- Superior Corrosion Resistance: The gold plating forms a dense protective layer on the Wave Spring surface, resisting electrochemical oxidation and chemical erosion, thus enabling the Wave Spring to maintain performance in humid or corrosive environments for extended periods.
- Stable Electrical Conductivity: The gold-plated surface of the Wave Spring reduces contact resistance between the Wave Spring and battery components, ensuring uninterrupted current transmission and stable operation of host devices.
Precision Machining Standard
The surface of the Wave Spring undergoes precision polishing to achieve a smooth, burr-free finish. This manufacturing standard ensures the Wave Spring meets the strict tolerance requirements of precision battery internal assembly, eliminating short circuits or component damage that could arise from surface defects of the Wave Spring.
Compatibility & Supporting System
Broad Product Compatibility
While optimized for CR2032 battery boxes, the Wave Spring is part of a versatile product line that supports mainstream button battery models including CR2016, CR2025, and CR2450. This compatibility expands the application scope of the Wave Spring, covering diverse electronic device scenarios that require reliable elastic contact.
One-stop Procurement Solution
To complement the Wave Spring, we offer a complete product portfolio including multi-material battery boxes (304ss/316ss/aluminum coating), multi-specification gaskets, and conical springs. This integrated solution allows customers to achieve one-stop procurement of battery assembly components centered on the Wave Spring.
Core Functional Highlights
- Precise Elastic Contact: The Wave Spring provides consistent and uniform pressure, ensuring tight contact between battery electrodes and external circuits. This critical function of the Wave Spring eliminates contact failure caused by vibration or deformation during device operation.
- Buffering & Pressure Reduction: The Wave Spring effectively absorbs expansion and contraction stress of battery components during charge-discharge cycles. By mitigating mechanical stress, the Wave Spring prevents structural damage to the battery and extends its overall service life.
- Stable Current Conduction: The gold-plated surface of the Wave Spring maintains low contact resistance even under prolonged use, ensuring stable current output. This feature makes the Wave Spring particularly suitable for mid-to-high-end electronic devices with high-reliability requirements.
Application Scenarios
As a core elastic component for button batteries (扣电), the Wave Spring is ideally suited for mid-to-high-end electronic devices that demand exceptional corrosion resistance and conductivity:
- Smart wearable devices: Smart watches, fitness trackers, wireless earbuds
- Industrial equipment: High-precision sensors, remote monitoring terminals, automated control modules
- Medical instruments: Portable diagnostic devices, wearable health monitors, low-power medical equipment
- Production & R&D fields: Battery assembly lines, equipment maintenance, scientific research testing platforms
Quality Compliance
All stainless steel raw materials for the Wave Spring comply with ASTM A240 international standards, ensuring excellent mechanical properties and elastic stability of the Wave Spring. The gold-plating process of the Wave Spring meets ASTM B456 specifications, guaranteeing uniform coating thickness and adhesion strength. Additionally, the dimensional accuracy of the Wave Spring conforms to ISO 286 tolerance standards, fully meeting the assembly requirements of precision electronic components.
