In addition to ultra-fine wires, cables and
stranded wires made of ISA-CON®414,
Isabellenhütte is now also manufacturing semi-
finished products/preliminary materials for
fasteners, such as screws and bolts, made of
ISA-CON®450, another version of the copper-
based alloy. This reduces electrical resistance
and thus heat development in the system. In
addition, undesired heat can be dissipated
better. (similar to that of stainless steel) and high
conductivity (similar to that of copper). With ISA-
CON®450, the tensile strength is between 450 and
550 megapascals and the conductivity is 80 percent
ACS (International Annealed Copper Standard). This
combination makes the material ideal as a conductive
fastener, for example as a bolt, screw, spring contact,
plug connector or bus bar.
Both types of material, ISA-CON®414 and ISA-
CON®450, are characterized by a high strength When problems occur by using fasteners made
of steel, for example, due to excessively high
