SMA 48, 50 - These alloys possess a very high saturation flux density of any Nickel-Iron alloy. This high saturation flux density combined with high magnetic permeability and low core loss makes them versatile alloys with many potential applications. They are primarily used in laminated cores for instrument transformers, magnetic shield and cores for all certain electronic and communications devices in which extremely high permeability at low magnetizing forces greatly increases the efficiency and effectiveness of the equipment.

A wide range of Nickel and Nickel based clad alloys are available from JLC for welding wires, welding electrodes and core wires of welding electrodes.

These are alloys with high melting point, good conductivity, low discharge potential , good corrosion resistance to carbon and sulphur. The use of this alloy is as the earth electrode as well as the centre electrode in the spark plug.

TC 30/TC 32 - Temperature Compensating Iron-Nickel alloys are used for applications where magnetic shunts are used for temperature compensation. Most frequently it is used for temperature compensation in energy meters, speedometers and temperature regulation devices. Even after very high variations in temperature, no changes have been found in the magnetic properties of these alloys.

TC 32	199°C	8.11 gm/cm³	80 μΩ-cm

JLC produces a wide range of thermocouple materials that are used to manufacture thermocouples, extension and compensating wires/cables. At JCL, we start with right selection of best available raw material to achieve the required chemical composition. A correct chemical composition is necessary to give uniform and exact thermocouple properties. The alloys are melted, hot-rolled and processed to final sizes using state-of-the-art technology. JLC believes in continuous improvement; all the processes are constantly monitored at each step using statistical process control tools to ensure the best quality of the final products.
