Exceptional mechanical strength
LEONI Histral® H18 stands for a composite material consisting of a copper-clad steel core. It allows for the excellent mechanical qualities of steel and the very good electrical properties of copper to be combined. In an environment characterised by marked vibrations or significant mechanical stress LEONI Histral® H18 is a good choice.
Good resistivity
Copper ranks second to silver as an electrical conductor. The copper coating in LEONI Histral® H18 makes for a good electrical conductivity without hampering the outstanding mechanical resilience. The resistivity LEONI Histral® H18 provides lends itself well to heating applications, too. Even at relatively low cross-sections the required heating power can be achieved.
Special Applications
Automotive
LEONI Histral® H18 is particularly suitable for seat heating as well as for signal or data cables.
Heating conductors
The high mechanical strength of LEONI Histral® H18, in combination with a good resistance value, renders it particularly suitable for heating applications. Its steel core prevents the material from getting soft in such applications.
High-frequency (HF) technology / coaxial cables
In HF technology the so-called "skin effect“ (link to our article about "High-frequency (HF) technology") ensures that the current flow is restricted to a very thin layer situated on the surface of the conductor and that the overall resistance in the conductor is reduced. LEONI Histral® H18 has copper, which features good electrical, in the cladding only. The additional galvanic plating of the surface causes the skin effect to be optimized.
