Abstract
Alloy compositions based on ternary alloys of the chromium-cobalt-iron system modified by addition of zirconium molybdenum, niobium, vanadium, titanium, and/or aluminum, are found to manifest improved formability. Exemplary compositions are magnetic and evidence coercivities of 350-550 Oe., remanent magnetizations of from 10,000 - 7,500 Gauss, and maximum energy products in excess of one million. Improvement in formability may take the form of room temperature stamping, sometimes in air, to final configurations including curvatures of radius equal to thickness. Novel compositions particularly desirable from such standpoint necessarily contain zirconium together with aluminum, niobium, and/or titanium.
