In automotive applications, the switch to bimetallics is relatively easy and represents a great value. Products of interest to the automotive industry are Copperlite™ Copper Clad Aluminum (10% by volume CCA) in accordance with ASTM B566 and genuine Copperweld® Copper-Clad Steel wire (CCS) in accordance with ASTM B227 and B910.
From applications in power cables carrying current, including battery cables and power leads to components such as lights, Copperlite™ CCA is the engineered solution to replace Copper. Hard-drawn Copperlite™ CCA strands can have mechanical and physical properties that are similar to copper wire.
For cables that have both mechanical and electrical functions, or are exposed to extreme vibration or hazards of mechanical damage, genuine 40% IACS hard-drawn Copperweld® wire is the product recommended for most automotive applications. Copperweld® cables can replace copper cables in all applications where cables are sized on strength rather than ampacity, particularly low current and signal leads.
When it comes to railroads, timeliness and safety are the primary concerns. Copperweld® line wires provide railway communication and signal lines with the safety and dependability essential in all phases of rail operation. With high-strength steel at their core, Copperweld’s line wires are stronger than copper or bronze, but with the copper layer carrying both the power and the signal, the conductivity remains quite high.
Genuine Copperweld® line wire is available in two conductivity grades, 30% and 40% of the conductance of a copper wire of the same size, the choice depending on the application. The wire’s strength and conductance are maintained throughout its long life of the wire thanks to the thick, corrosion-resistant covering of copper inseparably welded to the steel core. Copperweld® wires are available bare or with any of the standard coverings or insulations.
Copperweld® is a great benefit to the electrified railway. Along with other qualities, the wire is theft-resistant, and ideal for deployment in isolated, unguarded areas.
