What are the purity and thickness specifications of the aluminum coating on this disc spring?
The aluminum coating has a purity of 99.9% and a thickness of approximately 1 µm, as stated in the technical specifications. These parameters ensure consistent electrical contact and minimize contamination in coin cell assemblies.
What are the precise dimensions of this disc spring, and what is the packaging quantity?
The disc spring has a diameter of 15.4 mm, a height of 1.20 ± 0.03 mm, and a thickness of 0.20 mm. It is packaged in quantities of 60 pieces per bag, as specified in the basic packaging specification.
The Aluminum-Coated Disc Spring for Coin Cells combines a 304 stainless steel disc spring with a 99.9% purity aluminum coating to provide mechanical support and electrical contact in coin cell assemblies. Its precision dimensions and thin coating require careful handling and compatibility verification for optimal performance.
Positive
- High-purity aluminum coating: The 99.9% pure aluminum coating with approximately 1 µm thickness on 304 stainless steel provides a corrosion-resistant, conductive surface optimized for coin cell internal contact.
- Precision disc spring profile: With a 15.4 mm diameter, 1.20 mm height, and 0.20 mm thickness, the disc spring delivers consistent mechanical support and maintains electrical contact within coin cell assemblies.
Trade-offs
- Thin coating vulnerability: The 1 µm aluminum coating is susceptible to mechanical abrasion or damage during assembly, requiring careful handling to preserve the conductive surface.
- Application-specific compatibility: The spring dimensions and force profile must be verified against the specific coin cell case and electrode stack to ensure proper fit and contact pressure.
