CR/LIR2032 Stainless Steel Coin Cell Case with Black Sealing Ring

Application:
Designed for battery material research and coin cell assembly. The black sealing ring (gasket) aids in visual identification and sealing performance for specific experimental setups.

Key Features:
* Distinctive Sealing Ring: Features a black sealing gasket (O-ring) distinguishing it from standard white-gasket cases, useful for color-coding experiments or specific sealing requirements.
* Material Purity: Manufactured from high-quality 304 Stainless Steel, conforming to ASTM A276/A276M-2017 standards for chemical stability and corrosion resistance.
* Precision Dimensions: Finished product dimensions are strictly controlled to standard 2032 specifications, compatible with standard crimping machines.
