*** Depending on material combination & construction
The electrical conductivity of LEONI Histral® H85 can exceed 85 % IACS (International Annealed Copper Standard). This is extremely favourable compared to most alterative materials in its category, and surpasses the requirements of the most exacting specifications within its applications.
High mechanical strength
The tensile strength of LEONI Histral® H85 exceeds the highest expectations of the traditional “Copper-Cadmium” category of high strength / high conductivity copper alloys. This alloy is therefore ideally suited to applications where the finished product is exposed to a high degree of tension and drag – for example in automotive and aerospace environments where the finished cable is pulled through small openings. The high strength characteristic allows for smaller and lighter conductors, without performance loss.
Flex Life properties
LEONI Histral® H85 gives above average performance levels in situations where vibration or constant flexing is present. It can be stranded or braided for optimum flexibility.
LEONI Histral® H85 conductors can be up to 25 % lighter compared to standard copper conductors. This appreciable weight saving is crucial in today’s commercial and military aviation market, and is becoming increasingly important in the automotive industry – with continual innovations in new technologies such as performance monitoring, enhanced comfort and the ever-increasing electrification of vehicles.
High temperature resistance
High tensile strength is maintained even at high temperatures. LEONI Histral® H85 can be silver plated, where solderable connections are required, and can be nickel plated – up to 27 % nickel plate – for ultimate temperature resistance and for protection in harsh environments.
LEONI Histral® H85 meets the requirements of EN 2083, EN 4434, ISO 2635 and BS 3G 231. The extremely high tensile strength of the alloy ensures that there are no installation issues. The weight saving of up to 25 % achieved by using smaller cross sections is a significant benefit. Strands of 19 x 0.12 mm and 19 x 0.10 mm have been successful and are widely used for signal transmission in cockpit, communication and entertainment areas.
With its exceptional strength LEONI Histral® H85 is an ideal solution for shielding cables that undergo a wide range of mechanical stresses. The potential for miniaturisation offers an additional advantage – with many composite cables containing various cross sections, an excellent shielding braid that requires minimal space is extremely important.
In particular the automation and robotics industry makes extremely high demands on signal cables. Constantly changing tensions along with vibration and flexing require conductors with excellent strength and flexibility.
The exceptionally high mechanical strength of LEONI Histral® H85 means that it can be drawn down to diameters as fine as AWG50 (0.025 mm) whilst still retaining its performance characteristics.
Micro data cables
Electronic devices are constantly getting smaller and ever more powerful. Whether in folding mobile phones, laptops or other small communication devices ultra-thin cables are on the increase.
