A spinodal decomposition type ternary magnetic allioy is provided which contains, by weight, 3 to 40% vanadium, 5 to 45% chromium and the balance essentially iron. Optionally the alloy may contain at least one additional element, said additional element being present individually in an amount of 0.1 to 5% by weight and not greater than the amount of either vanadium or chromium. The alloy is easy to work and has excellent hard or semi-hard magnetic properties comparable with those of conventional iron-chromium-cobalt alloys. Yet the alloy is low in material cost and simple and inexpensive to manufacture.

A method of electrical machining by the travelling-wire EDM process is improved by utilizing as the wire electrode for increased removal rate and reduced wear an electrode material which is drawn from a composition of 0.1 to 3% by weight zirconium, 0.3 to 10% zinc and the balance copper.

Electrode material for travelling-wire type electrical discharge

A spinodal decomposition-type alloy is thermomagnetically treated for a specific time period at a temperature determined by calculating the spinodal curves of the alloy.

A rollable or plastically deformable Sendust-type magnetic alloy containing by weight 3 to 8% aluminum, 4 to 8% silicon, 0.1 to 2% niobium or tantalum or mixture thereof, 0.5 to 7% a mixture of vanadium and copper and the balance iron. The alloy is especially suitable for use with high-frequency inputs.
