The 3SX Hardwire
is a high carbon steel cord with a micro-fine brass or AO-brass (Adhesion
Optimized) coating. The 3SX cord is used where balanced compressive and
tensile strengths are required as well as better mechanical bonding characteristics
than the 3S. The 3SX cord is made by twisting three identical wire filaments
together at a longer than usual lay length and then over-wrapping the
bundle with a single filament. The result is a cord with lower twist angles
and straighter filaments that is the basis for the increased compressive
strengths.
Characteristics:
3SX tapes
have the highest compressive strengths of all Hardwire tapes and tend
to match or exceed the tensile properties.
Increased
mechanical bonding in resins.
Better
interlaminar shear resistance.
The cords
do not bloom in failure modes during compression or tension.
Laminates
exhibit steel like characteristics with high ductility and extreme deflection
capability.
Very high
flexural strength as well as ductile failure modes (laminates tend to
bend - not break).
The best
tape for bending angles and can be done in standard sheet metal breaks.
Very boardy
feel - excellent for flat surfaces but still conformable enough for
curved structures.
Better
handling characteristics and cutability than 3S tapes.
