Excellent properties

Low weight
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.
Good resistivity (specific resistance)
Copper ranks second to silver as an electrical conductor. The copper cladding of LEONI Histral® H16 ensures a good electrical conductivity whenever mechanical properties do not play a primary role.
Environmentally friendly
LEONI Histral® is RoHS compliant in accordance with UE Directive 2011/65/EG. The materials contain no cadmium or other harmful elements and meet the high demands placed on modern eco-friendly materials. They are also fully compliant with all current REACh legislation. In response to inquiries made, we can confirm that our products do not contain any minerals that originate from regions of conflict. They are in full accordance with the American Dodd-Frank-Act.

Aluminum is a fairly abundant material that can be recycled in a lot of ways, thus it contributes to saving valuable resources.


Special applications

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“ 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.
Shielding braids
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.
Heating conductors
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.
