Superior Fatigue resistance
Steel wire, by its nature, has limits. When pushed to its extreme in terms of tensile strength, wire becomes brittle and loses its flexibility. Ultra-Pac’sTM improved fatigue properties are derived from the combination of Ultra-pac’sTM flexible construction and the compacted strands.
The compacted strand has very favorable internal contact conditions when compared with the point contact of round wires within a normal strand. These reduce internal friction and nicking for a longer fatigue life.
