YunfuDisc washer

The nickel butterfly gasket uses nickel as its core raw material. Cleverly borrowing from biomimetic principles, it is crafted into a unique butterfly structure through advanced precision processing technology. This innovative design not only optimizes stress distribution but also fully leverages the intelligent properties of the nickel, giving it unique shape memory function, high elasticity, and excellent environmental adaptability. It is a high-quality industrial component that combines sealing and shock absorption functions.
