Higher flex life results
LEONI Histral® R15 provides exceptional flex life and offers best performance in high vibration and movement situations.
High temperature performance
The high strength is maintained at elevated temperatures.
Good resistivity (specific resistance)
LEONI Histral® R15 is an ideal material for heating elements.
High corrosion resistance
LEONI Histral® R15 is an alloy of copper and tin, commonly called bronze. Bronze is highly corrosion resistant as proved by the large number of Bronze Age (about 2200-800BC) tools that are still being found intact.
LEONI Histral® R15 is suitable for soldering, crimping and ultrasonic welding.
Very low temperature coefficient
This shows the relative change of resistance as the temperature rises or falls. Almost all metals have a positive temperature coefficient, meaning that as the temperature increases so does the resistance. This is of particular significance in heating cables and elements. The lower the temperature coefficient of a heating cable, the more uniform the heating power as temperature increases. The temperature coefficient of LEONI Histral® R15 at 0.00065 is lower than that of CuNi6 (0.00072), currently the most widely used conductor in heating cables and elements.
Improved safety reduces failure risk
Under similar electrical and thermal conditions LEONI Histral® R15 has a significantly longer operational life compared with CuNi6.
Signal cables in robotics face very high mechanical demands. In medical equipment these conductors are required to provide the precision and reliability that are vital for patient safety.
Heating mats and electric blankets
Heating mats, similar to carpets or rugs on the floor, and subject to high mechanical stress.
Car seat heating
Glued or stitched heating areas on non-woven fabrics for original equipment or retro-fitting.
Steering wheel heating
In addition to seat heating woven or stitched heating areas on non-woven fabrics, shaped and contoured for steering wheels.
Hose heating, e.g. for AdBlue® hoses
Hose heating can be used for different industrial applications.
AdBlue® hoses are needed for mobile vehicles. AdBlue® is a solution synthetically generated from high-purity urea in de-mineralized water. It is applied whenever exhaust fumes are re-treated in an SCR-catalyst. The solution needs to be kept heated because of its early freezing point at –11 °C.
