ALLOY FOR PERMANENT MAGNETS Russian patent published in 1995 - IPC

Abstract SU 1332848 A1

FIELD: alloys. SUBSTANCE: alloy has the following components, wt.-%: Co 12.5-40; Ni 10-16; Al 7-9; Ti 0.1-5; Cu 1-3.5; Hf 0.1-0.8; Nb 0.1-0.8; Mn 0.1-1.0; Si 0.1-1.0; S 0.2-0.3, and Fe - the rest. Alloy deoxidation with manganese, silicon and sulfur results in more complete deoxidation and purity by oxygen, nitrogen and nonmetallic inclusions. Negative effect of titanium is neutralized, polishing is improved, and formed sulfides act as lubricant. Alloy properties: Br = 8000-13000 Gs; Hc = 640-1800 E; (BH)_max = 3.6-7.0 mln Gs x E; σ = 12000 - 20000 kg/cm². EFFECT: increased magnetic properties of alloy. 2 tbl
