Automotive Wire Harness Study Offers New Information on Material Substitution

NEW YORK—The International Copper Association, Ltd. (ICA), the leading authority on the fundamentals of copper demand, issued preliminary findings from a study by The Martec Group today demonstrating the overall impact of substitution in the automotive wire harness industry. The study shows that nearly 95 percent of the automotive wire harness will remain copper in 2020, indicating that substitution will have limited influence on the copper market.

The Martec Group study indicates that estimates among leading automotive manufacturers place the total reduction of copper in the wire harness to be only 0.8kg per car at its “worst case” scenario by 2020. This calculation includes the expected reduction of copper usage in automotive battery cables and wire harnesses as manufacturers look to reduce vehicles’ overall weight. Although manufacturers are making smaller, more-fuel-efficient cars, research confirms the overall impact on copper to be minimal.

“Copper use in automotive wire harness is ubiquitous, and it is a critical element in a vehicle’s manufacturing,” said Colin Bennett, global manager, market intelligence and data, ICA. “As the data shows, the potential for substitution in automotive wire harness is limited through 2020.”

According to the study, growth in electronics feature content (i.e., infotainment/navigation, telemetry, automated safety systems and autonomous driving demand), as well as the expanding production of electric and hybrid vehicles, will create a surge for the automotive copper market. Electric and hybrid vehicles require more copper use due to higher power/voltage requirements necessary for that category. The study reveals overall global vehicle production is expected to increase from about 92,500,000 total vehicles in 2016 to almost 102,000,000 by 2020.

A wire harness is the set of wires, terminals and connectors running throughout the entire vehicle. It relays information and electric power to keep the vehicle’s components communicating with each other. The wire harness plays a critical role in a vehicle’s overall operation and reliability. Copper is widely used and highly regarded in the automotive market due to its high conductivity, ductility and reliability in transmitting electrical information from one system to another.

While weight and cost are cited as the primary drivers for potential material substitution, the evolution of the automobile plays an important role in the use of copper. Since manufacturers are looking to produce smaller and lighter vehicles, they need hardware to support those efforts without losing quality. As they look into smaller gauge wires to support increased feature content and combat overall vehicle weight, copper remains the preferred material to handle these issues.

Additional findings from this study will be discussed at ICA’s upcoming Market Update on Copper Use on Friday, 28 October 2016, prior to LME Week in London.

Confidence in Pricing Strategies in Times of Volatility

A conflation of current events has created both upward and downward pressure on consumer prices—persistent rising inflation posing a risk to demand, combined with disruptions in the supply chain raising production costs at the same time. Simultaneously, many companies are seeing shrinking profit margins meeting potentially slowing demand. The reflexive course of action during inflationary
