Formula: Co 49/Fe 49/V 2
Form: Rod
Material: Cobalt/Iron/Vanadium (Permendur® 49)
Commodity: Alloys
Permendur® 49 Rod is a soft‑magnetic alloy used to create responsive magnetic circuits with low loss and clean, repeatable behavior across typical operating frequencies. Designers value its ability to deliver high permeability at modest magnetizing forces, which enables compact devices with precise control and quiet operation. Aerospace, automotive, and industrial electronics apply it in cores, shields, relays, and solenoids where sensitivity and stability matter more than brute force. The rod form machines into pins, poles, sleeves, and custom shapes for quick trials and small‑lot builds, letting teams tune geometry alongside heat treatment for the target waveform and flux range. Because final properties depend on processing, the material supports tailored performance for instrument transformers, actuators, and magnetic sensors. In labs and production alike, Permendur 49 provides a reliable foundation for efficient electromagnetic components that respond predictably and age gracefully.
