Benefiting from a high resistivity, resistive alloys are ideal for use at high temperatures. Depending on the application, either Nickel-Chromium, Iron-Chromium-Aluminium or Copper-Nickel alloys can be used.
Through the addition of special elements, IMPHY GILPHY 80 has a good high temperature stability and a welladhering oxide scale even under cyclic conditions. IMPHY GILPHY 80 has a maximum service temperature of 1200°C.
The grades IMPHY GILPHY are available in various chemical compositions. Please contact us
RESISTOHM 80 gives extraordinary performances at temperatures up to 1200°C and will be operational at those high temperatures under the most exacting conditions.
This is an excellent choice for heating elements operating at a temperature up to 1100°C.
RESISTOHM 135 is a ferritic alloy of the FeCrAl family, which can be used as heating element of resistance up to 1200°C.
RESISTOHM 125 is a ferritic alloy of the FeCrAl family, which can be used at temperatures up to 1200°C.
RESISTOHM 200 /200 T has very good characteristics of malleability and solderability. Moreover it has an excellent resistance to corrosion.
RESISTOHM 201 is used for replacement of Nickel 200 when very high qualities of malleability are required.
This nuance of nickel preserves all the particularities of pure nickel but has been light strenghtened with an addition of manganese.
Physical and electrical characteristics of Resistohm® 40CB and Resistohm® 40 are similar, except that Resistohm® 40CB benefits from a specific addition of Columbium (1%).
Its high temperature coefficient allows it a speeder rise in temperature than the other NiCr.
Its high chromium percentage (30%) gives RESISTOHM 70 a very good life time in the furnace application. Elements in RESISTOHM 70 have also a satisfactory life time when operating atmosphere is alternatively oxidizing and reducting.
RESISTOHM 20 is placed at the limit between heat resistant alloys and stainless steels. It can be used for heating elements at low temperature, or as cold connections of a furnace.
This alloy can reach very high use temperature, particularly useful for heating elements of industrial furnaces where a high head rate is necessary. A very long life time of the elements operating at high temperatures up to 1280°C is is guaranteed...
RESISTOHM 145 is a ferritic alloy of the FeCrAl family, which can be used up to 1300°C in case of big diameters.
RESISTOHM Y, Iron-Chromium-Aluminium alloy with a content of Yttrium, has a very good behavior to creeping. In addition, it has a very good life-time, especially, at very high temperature and with important thermal cycles.
RESISTOHM 30 presents the same applications fields as Resistohm 40 but with a little lower resistivity which imposes a maximum operating temperature of 1000°C and a higher ventilation as for RESISTOHM 40.
This Iron-Chromium-Aluminium alloy with an high content of Yttrium (> 0.05 %) and addition of rare earths, has been developed and produced for working temperatures up to 1300 °C.
