FeNi52 Alloy for Reed Switches

Designed for reed switch blades, this alloy is engineered to balance magnetic permeability, elastic restoring force, and CTE compatibility with sealing glass. A China-made material option, this alloy combines high performance with low cost. Reed switches using this alloy demonstrate millisecond-range response and over one million operating cycles.

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.
