３００℃以下である。However, conventional magnetic alloys have high melting temperatures; for example, silicon copper, which is well known as a high magnetic permeability alloy, has a high melting temperature.
It is about 1500°C, and about 1450°C for permalloy alloys. Therefore, when melting and casting these alloys, a high frequency melting furnace or an arc melting furnace is used. However, although there has been a desire for an alloy among magnetic alloys that can be extremely easily melted and cast, there has been no suitable one to date. The alloys that can be melted and cast into notebooks in this way can be used, for example, in small amounts using city gas, which is usually easily available in university laboratories, or in extremely simple melting furnaces in which oxygen is added to city gas. This is required when creating magnetic alloys for use in experiments, or when producing alloys for dental prosthetics using melting equipment normally owned by dentists or dental technicians. Although it varies depending on the structure of the melting furnace, the melting point of metals that can be melted in a gas melting furnace made by adding oxygen to city gas is approximately 1.
The temperature is 300°C or less.

を特徴とするものである。There are 14 high-performance small melting furnaces that can perform high-frequency melting.
It is also possible to melt alloys with melting temperatures above 00°C.
However, in the case of small quantities of samples that are normally melted in the atmosphere, it is necessary to melt them in as short a time as possible to facilitate casting, and being able to perform the work at temperatures below 1350°C facilitates that purpose. will be achieved. Therefore, it has been strongly desired to develop a magnetic alloy having a melting temperature of preferably 1300° C. or lower, and if unavoidable, 1350° C. or lower. In order to be generally used as a magnetic alloy, a saturation magnetic flux density of at least 2000G or more is required.
In addition, for applications primarily used in dentistry, excellent corrosion resistance is required. Furthermore, for special uses, it is necessary to have excellent porcelain scorching properties. The purpose of the present invention is to provide a novel low melting point magnetic alloy having a melting temperature of 1350° C. or less and excellent corrosion resistance. In order to achieve the above object, the present invention provides Ni29 to 40% by weight.
