Title:
PRODUCTION OF SEMIHARD MAGNETIC MATERIAL OF FE-CU-CO ALLOY
Document Type and Number:
Japanese Patent JPH08283856
Kind Code:
A
Abstract:
PURPOSE: To obtain an Fe-Cu-Co alloy for a semihard magnetic material having high residual magnetic flux density and high coercive force and excellent in squareness ratio and cold workability.
CONSTITUTION: A molten metal consisting of, by weight, 20-60% Cu, 1.00-20% Co, 0.1-7.0% Al and the balance Fe with inevitable impurities or further contg. 0.1-10% Mn and 1-10% Cr is cast into a metallic sheet of 0.1-8mm thickness at ≥100°C/sec solidification cooling rate. This metallic sheet is cold-rolled at 70-98% draft and aged in the temp. range of 350-650°C to produce the objective semihard magnetic material.
