6×25F-IWRC

The 6×25F-IWRC (also commonly designated as 6×25Fi-IWRC) is a high-performance wire rope featuring a classic Filler-type construction, line contact, and an Independent Wire Rope Core (IWRC). By combining a Filler-type configuration with a steel core, it achieves an optimal balance of high strength and superior crush resistance while maintaining excellent flexibility, making it a mainstay product for lifting, mining, and piling machinery.

The "25F" designation indicates that each strand consists of 25 wires arranged in a Filler pattern; fine filler wires are inserted into the gaps between the inner and outer wire layers, creating tight line contact between the wires. This structure enhances the metallic cross-sectional area and structural stability while preserving flexibility; it ensures more uniform load distribution and eliminates secondary bending stresses. Reduced internal friction effectively prevents fatigue-induced wire breaks caused by repeated bending, resulting in outstanding wear resistance.
