Material: 304 Stainless Steel with Aluminum Coating
Brand: Xnergy
Product Introduction
This aluminum-coated funnel spring is designed for coin cell battery assembly, offering improved corrosion resistance and stable electrochemical performance compared to standard stainless-steel springs. The 304 stainless steel spring is coated with 99.9% purity aluminum to a thickness of 1 μm, providing better corrosion resistance and the ability to withstand higher voltages (up to 5 V). The aluminum coating also prevents reactions between the electrolyte and the stainless-steel spring surface.
Key Features
• Aluminum-coated surface — 99.9% purity Al, 1 μm thickness
• Up to 5 V compatibility — Al coating enables use with higher-voltage electrolyte systems
• Reduced electrolyte–metal reactions — coating prevents direct contact between electrolyte and stainless steel
• 304 stainless steel base — provides mechanical strength and spring performance
• Available in 60 sets/bag or 30 sets/bag
