This glass bonding material () is made of a cladding material () in which at least a first layer () made of an Al-based alloy and configured to be bonded to glass and a second layer () made of an Fe&#x2014;Ni based alloy having a thermal expansion coefficient from 30&#xb0; C. to 400&#xb0; C. of 11.5&#xd7;10(K) or less are bonded.

Glass bonding material and multilayer glass

A semi-hard magnetic material that is formed with equal to or more than 5.0% but less than 13.0% of Ni by mass, equal to or more than 0.5% but equal to or less than 4.0% of Mn by mass, more than 0% but equal to or less than 3.0% of Al by mass, more than 0% but equal to or less than 1.0% of Ti by mass and a remainder of Fe and an impurity, that has a coercivity of 1000 to 2400 A/m and that has a residual magnetic flux density of 1.3 T or more. A method of manufacturing the above semi-hard magnetic material wherein the material is a thin plate having a thickness of 0.030 to 0.30 mm and, after a cold rolling, performing an aging treatment on the thin plate at a temperature of 520&#xb0; C. to 680&#xb0; C.
