- LEONI Histral® H16 is a composite material, made up of an aluminum core, which has a copper coating, also known as copper-clad aluminum. This allows for the positive mechanical properties of copper to be combined with the very low net weight of aluminum. LEONI Histral® H16 lends itself extremely well to applications for which weight plays a crucial role while good electrical properties are also required. LEONI Histral® H16 boasts a material length per kilogram produced that exceeds that of copper by a factor of about 2.4, while it still attains 64 % of the conductivity provided by bare copper.
Aviation and automotive industry
Weight is of major importance for the construction of airplanes and automobiles. LEONI Histral® H16 is particularly suited for larger cross-sections here that can be employed for the transmission of power, where there is a significant weight reduction potential.
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® H16 has copper, which features good electrical, in the cladding only. The additional galvanic plating of the surface causes the skin effect to be optimized.
LEONI Histral® H16 features a resistivity lending itself well to shielding braids because high coverage can be achieved at a comparatively low weight. The fact that aluminum suffers from the drawback of having a poor contact resistance is largely offset by the copper cladding.
The combination of a relatively good resistance value with a rather low mechanical resilience suggest that LEONI Histral® H16 may well be used in all kinds of heating applications that are not exposed to a permanently varying level of stress.
