How Much Copper is in an Electric Vehicle?

Copper’s special relationship with electricity has been apparent since ship designers first regularly began installing copper to protect the masts of wooden ships from lightning in the early 19th century.

Today, of course, you might be more used to seeing copper’s electrical applications through the use of power lines, telephone wires, and wiring in practically every major home appliance you own.

Millions of tons get used for these applications every year, but it is still early days for copper’s use in electrification. That’s because copper will continue to be a critical component of the green energy revolution, thanks to the rising adoption of battery-powered vehicles.

Why Copper?

Today’s visualization comes to us from Canadian Platinum Corp., and it focuses on showing how much copper is in an electric vehicle, along with the properties that make it the ideal choice for an EV-powered future.

Here is why copper is a crucial component to vehicle manufacturers:

Cost
Copper costs roughly $0.20 per ounce, compared to silver ($15/oz) and gold ($1200/oz), making it by far the cheapest option for electrical wire.

Conductivity:
Copper is nearly as conductive as silver – the most conductive metal – but comes at a fraction of the cost.

Ductility:
Copper can easily be shaped into wire, which is important for most electrical applications.

It’s also important to note that temperature does not affect copper’s conductivity, which makes the metal ideal for automobiles in all climates.

Copper in Gas vs. Electric Vehicles

The UBS Evidence Lab tore apart a traditional gas-powered vehicle as well as an EV to compare the different quantities of raw materials used.

What they found was crucial: there is 80% more copper in a Chevrolet Bolt, in comparison to a similar-sized Volkswagen Golf.

The major reason for this is that at the heart of every EV is an electric motor, which is built with copper, steel, and permanent magnets (rare earths). Electric motors tend to be much simpler than gas-powered engines, which have hundreds of moving parts.

Incredibly, in an electric motor, there can be more than a mile of copper wiring inside the stator.

The More Electric, the More Copper

According to Copper.org, along the scale from gas-powered cars to fully electrical vehicles, copper use increases dramatically.

Conventional gas-powered cars contain 18 to 49 lbs. of copper while a battery-powered EV contains 183 lbs. Meanwhile, for a fully electrical bus, a whopping 814 lbs. of copper is needed.

With the rapidly increasing adoption of electric vehicles, copper will be an essential material for the coming electrification of all forms of ground transport.

Copper is at the heart of the electric vehicle and the world will need more. By 2027, copper demand stemming from EVs is expected to increase by 1.7 million tonnes, which is a number just shy of China’s entire copper production in 2017.

Brass Rods: The Secure Choice

The unique combination of machinability and recyclability makes brass rods the secure choice for manufacturers seeking future-proof raw material solutions.

This infographic, from the Copper Development Association, shows three ways brass rods give manufacturers greater control and a license to grow in the competitive market for precision-machined and forged products.

Future-Proof Investments in New Machine Tools

A material’s machinability directly impacts machine throughput, which typically has the largest impact on machine shop profitability.

The high-speed machining capabilities of brass rods maximize machine tool performance, allowing manufacturers to run the material faster and longer without sacrificing tool life, chip formation, or surface quality.

The high machining efficiency of brass leads to reduced per-part costs, quicker return on investment (ROI) for new machine tools, and expanded production capacity for new projects.

Supply Security Through Closed Loop Recycling

Brass, like its parent element copper, can be infinitely recycled. 

In 2022, brass- and wire-rod mills accounted for the majority of the 830,000 tonnes of copper recycled from scrap in the United States.

Given that scrap ratios for machined parts typically range from 60-70% by weight, producing mills benefit from a secure and steady supply of clean scrap returned directly from customers, which is recycled to create new brass rods.

The high residual value of brass scrap creates a strong recycling incentive. Scrap buy back programs give manufacturers greater control over raw material net costs as scrap value is often factored into supplier purchase agreements.

Next Generation Alloys for a Lead-Free Future

Increasingly stringent global regulations continue to pressure manufacturers to minimize the use of materials containing trace amounts of lead and other harmful impurities.

The latest generation of brass-rod alloys is engineered to meet the most demanding criteria for lead leaching in drinking water and other sensitive applications.

Seven brass-rod alloys passed rigorous testing to become the only ‘Acceptable Materials’ against lower lead leaching criteria recently adopted in the national U.S. drinking water quality standard, NSF 61.
