Excellent properties

Medium conductivity

Signals are usually transmitted at fairly low amperage. The resistance level of LEONI Histral® H26 does therefore not lead to losses that might hamper the application. 

High mechanical strength

LEONI Histral® H26 is an extraordinarily strong copper alloy that clearly outperforms the mechanical properties of pure copper.

High Flex Life

LEONI Histral® H26 gives excellent performance levels in situations where vibration or constant flexing are present.

Low weight

The high mechanical strength of LEONI Histral® H26 allows for its individual wires to be drawn down to much smaller diameters than copper, which results in a substantial weight reduction.

Contact properties

The crimp qualities of LEONI Histral® H26 correspond to those of pure copper in hard condition. However, the tools applied have to be adapted to the lower cross-sections.

Special applications

Signal cables

LEONI Histral® H26 is particularly suitable for signal cables in robotics facing very high mechanical demands.

Brass wires can be found in a most diverse range of applications:

  • spark erosion wire (conductive materials are vaporized by applying sparks allowing for the conductor to be cut in this state)
  • brushes made from brass wire (high mechanical strength and malleability, particularly suited for processing soft metals such as gold, brass or copper)
  • decoration (e.g. the color of LEONI Histral® H26 looks very much like gold)
  • grids and sieves made from brass wire
