For one, the C7 core comprises seven (or more, depending on cable diameter) 3.2-mm/0.13-inch diameter strands of aerospace-grade carbon fiber pultruded with Fortron PPS (polyphenylene sulfide) from Celanese. The core is isolated from direct contact with the cable’s aluminum conductor strands by an overwrap of polyetheretherketone (PEEK), which protects the aluminum from galvanic corrosion and prevents abrasion of the core

The rare earths high iron aluminum alloy material, developed by the company, mixes aluminum and some special materials, for example, rare earths to change the physical properties, which results a non-ferrous materials “revolution". The alloy cable enjoys three advantages, such as performance, it shows 35% more of percentage elongation,50% more of resisting fatigue strength, 40% less of inverse elasticity, 10 more years of service life and stronger antioxidant and corrosion resistance than those of copper wire, because of rare earths element added in conductor and better insulating material; safety, it is contributed to adding the patent fire retardants so that the alloy cable can still function for light even on fire; and cost, 40% less than that of copper wire.

The electronic content, and thus the interconnect content, has been increasing in light vehicles, and this trend will continue through this forecast period.

Aluminum wire increasingly is used in passenger car wire harnesses. To reduce weight and improve gas mileage, the automotive companies are turning to aluminum wire, among other solutions. Aluminum wire always has the potential issue of galvanic corrosion between the wire and the beryllium-copper or phos-bronze contacts. Companies like TE Connectivity and Delphi have come up with solutions that alleviate this concern.
