Product Description 5J1580 Thermal Bimetal StripSimilar marks in different countryChinese mark:5J1580/5J16German mark:TB1577American mark:ASTM B388 TM-1DescriptionThermal bimetallic layer is composed of two layers with different linear Solid combination of expansion coefficient of metal composite materials.It holds the higher thermal sensitivity and high resistivity, low temperature stability is good, the welding is more easily and widely used. And it mainly is used for temperature measurement and automatic control equipment in the thermal sensitive element.Component laminations and Chemical content High expansive lamination(Active):Ni20Mn6Low expensive lamination(Passive):Ni36Chemical composition(%)GradeCSiMnPSNiCrCuFeNi36≤0.05≤0.3≤0.6≤0.02≤0.0235~37--Bal.

Wherein the higher expansion coefficient of the active layer is a layer called a low coefficient of expansion of the layer is named passive layer.Style of supplyAlloys NameTypeDimension OhmAlloy-5J1480StripW= 1~150mmT= 0.05-3.0mm
