Automotive Megatrends Drive 4.8% CAGR in Copper Demand till 2034 Receive US

Copper is a key mineral for the automotive business, used ubiquitously throughout the wiring harnesses market. Its demand is about to develop because of electrical car and autonomous car megatrends. IDTechEx’s model new report “Copper Demand for Automobiles 2024-2034: Developments, Utilization, Forecasts” finds the automotive copper demand will attain 5MT (1MT = 1 billion kilograms) of annual demand in 2034. Autonomy and electrification will drive the expansion from as we speak’s demand, however the part that dominates the demand will nonetheless be the wiring harness.

The wiring harness is the central nervous system for a automotive, connecting all of the sensors, actuators, lights, and extra to the car’s brains. Every part within the system would require a number of wires chargeable for communication and energy supply. With automobiles as we speak being so complicated, containing a whole lot of wired parts, the wiring harness has expanded to 1000’s of particular person wires, totaling kilometers of general size.


Some gamers, like Tesla, are working exhausting to optimize the networking of the car, reducing out system redundancy, 1000’s of meters of cables, and kilograms of weight per car. This may be helped with a system architectural change. Tier 2 suppliers, like NXP, foresee an rising zonal structure method the place wired parts are grouped by location somewhat than operate. This will help to eradicate redundancy within the wire harness, however IDTechEx has heard from business gamers that benefiting from zonal architectures requires extra of a harness-first mindset somewhat than the wiring being an afterthought.


Optimization is barely one of many threats to copper consumption in automobiles, substitution with aluminum, 48V programs with smaller gauges, and even wi-fi communication are all set to cut back copper within the wiring harness. These discount components are countered by the rising complexity of automobiles and the final measurement progress of automobiles, as bigger SUVs turn out to be ever extra well-liked. IDTechEx’s report “Copper Demand for Automobiles 2024-2034: Developments, Utilization, Forecasts” forecasts how these components will evolve over the subsequent ten years and the way they are going to impression copper demand within the automotive business.

Electrification would be the largest boon to copper demand for vehicles. Copper is used all through electrical car powertrains, from foils in every cell of the battery to the windings of an electrical motor. In complete, every electrical car can generate over 30kg of extra copper demand.


Like with the wiring harness, the copper demand within the electrical parts is about to alter. Future lithium-ion chemistries and applied sciences will have an effect on the copper depth of cells, with larger vitality cells usually returning decrease kg/kWh copper intensities. Whereas within the motor, IDTechEx has seen just lately revised curiosity in everlasting magnet-free motors due to neodymium worth volatility. Wound rotor synchronous motors are one instance the place the everlasting magnet is successfully changed with copper electromagnets, practically doubling the copper depth in comparison with common everlasting magnet motors.


Superior driver help system (ADAS) options and autonomous driving are extra developments that can generate extra demand for copper in automobiles. These programs depend on a set of sensors, together with cameras, radar, and LiDAR. Every of those provides further wiring within the car and makes use of copper of their inside circuit boards. Whereas the copper per sensor is comparatively small, usually just a little over 100 grams, the full copper sums to some kilograms for extremely automated automobiles filled with tens of sensors. Chief within the discipline, Waymo has a complete of 40 sensors, a complete which isn’t uncommon throughout different robotaxi gamers. Whereas these extremely automated automobiles will make up a minor a part of automotive gross sales in 2034, the widespread adoption of stage 3 applied sciences over the subsequent 10 years might be a big driver in copper utilization for ADAS and autonomous options.


For extra element on IDTechEx’s expectations for copper demand throughout completely different components of the car within the subsequent 10 years, see the extremely granular forecasts within the “Copper Demand for Automobiles 2024-2034: Developments, Utilization, Forecasts” report. The report contains copper demand cut up by utility within the automotive business, powertrain kind, stage of autonomy, regionality, and extra.
