Features & Benefits
Optimized Magnetic Properties
High initial magnetic permeability and low coercivity enable rapid, reliable switching under weak magnetic fields.
Strong Elastic Recovery
Optimized elastic properties help maintain contact force and support reliable operation over millions of switching cycles.
Controlled CTE Matching
4J52 alloy provides close CTE matching with sealing glass, helping reduce the risk of stress-induced cracking at the lead-to-glass seal.
Alternative to Imported Materials
Validated as an alternative to conventional imported materials such as Vacodil 52, delivering comparable performance while significantly improving cost efficiency.
High-Quality Surface
An ultra-clean, oxidation-controlled surface helps reduce contact resistance and extend switching life.
