Magnetic alloy having a low melting point

Abstract

A magnetic alloy having a relatively low melting point, particularly for dental use. The low melting point magnet alloy contains one or more elements of Co and Ni, a Co content of which being in the range of 79 wt. % or less, a Ni content being in the range of 80 wt. % or less, the remainder being essentially a Pd content.

What is claimed is: 
     
       1. A magnet alloy which consists essentially of Co, Ni and Pd, the content of Co being in the range of from 20 to .[.70.]. .Iadd.36 .Iaddend.weight %, the content of Ni being in the range of 29 to .[.80.]. .Iadd.45 .Iaddend.weight %, and the content of Pd being at least 35 weight %, said alloy having a magnetic flux density value B 100  of at least 2000 G and a melting point of not more than 1350° C. 
     
     
       2. A magnet alloy which consists essentially of Co, Ni, Pd and at least one additive element, the content of Co being 20 to .[.70.]. .Iadd.36 .Iaddend.weight %, the content of Ni being in the range of 29 to .[.80.]. .Iadd.45 .Iaddend.weight %, the content of Pd being at least 35 weight % and the at least one additive element being selected from the group consisting of 15 weight % or less Cr, 30 weight % or less Fe, 20 weight % or less Cu, 3 weight % or less Zn, 3 weight % or less Sn, 20 weight % or less Pt, 23 weight % or less Au and 3 weight % or less Ag, said alloy having a magnetic flux density value B 100  of at least 2000 G and a melting point of not more than 1350° C. .Iadd. 
     
     
       3.  A magnet alloy which consists of Co, Ni and Pd, and inevitable impurities, the content of Co being in the range of from 7 to 50 weight %, the content of Ni being in the range of 15 to 58 weight %, and the content of Pd being at least 35 wt. %, the alloy having a magnetic flux density value B 100  of at least 2,000 G and a melting point of not more than 1350° C. .Iaddend. .Iadd.4. A magnet alloy which consists of Co, Ni, Pd, at least one additive element, and inevitable impurities, the content of Co being 7 to 50 weight %, the content of Ni being 15 to 58 weight %, the content of Pd being at least 35 weight % and the at least one additive element being selected from the group consisting of 15 weight % or less Cr, 30 weight % or less Fe, 20 weight % or less Cu, 3 weight % or less Zn, 20 weight % or less Pt, 23 weight % or less Au and 3 weight % or less Ag, the alloy having a magnetic flux density value B 100  of at least 2,000 G and a melting point of not more than 1350° C.
