Greater strength with less weight
The specific gravity of aramid fibers is
only 1.44 g/cc, compared to copper at 8.9 g/cc. Even with the
addition of metal coatings, the specific gravity of ARACON
fibers ranges from 3 to 5 g/cc. At the same time, the tensile
strength of the aramid core (350 Ksi) is from three to ten times higher
than that of traditional or high-strength copper cores (35-95
Ksi).
Flexibility that never tires
Since ARACON
fibers are textile-like at heart, they offer a "hand" or feel that is
far more flexible and compliant than metal. And, in a
side-by-side flexibility test, copper wire broke after 50 flexes, while
ARACON fiber was still going strong
when the test was stopped at 10,000 flexes.
Stability and compatibility
Aramid fibers have dramatically improved
thermal stability compared to commodity fibers such as nylon and
polyester. ARACON maintains
its strength both at elevated temperatures and under cryogenic
conditions. Moduli of aramids are in the same range as common
conductor metals, which makes aramids ideal substrates for cladding
with conductor metals. Thermal cycling tests show no increase
in resistance, confirming the excellent adhesion of metal to the aramid.
Electrical/mechanical properties
tailored for your needs
A wide range of properties is available by
varying the metal cladding type, thickness and the base fiber size.
Strands from 38 AWG to larger than 24 AWG can be
made from single or multiple bundles of ARACON.
Fiber resistance can be tailored from 100 to greater than
500,000 ohms per thousand feet.
