Who uses copper?

Construction and electrical uses dominate

About three-quarters of total copper use is electrical — power transmission and generation, building wiring, telecommunications, and electrical and electronic products, per USGS figures. Copper ranks third among industrial metals by quantity consumed, after iron and aluminum. The single largest end market is building construction, holding roughly 27 to 30% of consumption according to market analyses — driven by wiring, with 75 to 100 kilograms of copper in a typical new housing unit, plus plumbing tube, HVAC systems, and architectural applications. Electronics and electronic products come next, followed by transportation, industrial machinery, and consumer and general products. This is why demolition contractors, electricians, plumbers, and builders are the backbone of the copper scrap stream: every building torn down or renovated releases wiring, pipe, and equipment that was installed when copper was the default choice, because for most of the 20th century it was the only choice. Construction copper is also the most cyclical demand — it rises and falls with building activity — but the installed base in existing buildings guarantees a steady scrap flow regardless of the cycle.

Grids, EVs, and data centers

The demand story that matters most for the next twenty years is the grid. Wood Mackenzie's head of copper research calls grid expansion, reinforcement, and hardening the single most important driver of copper demand over the coming decades — the common denominator behind EV, renewable, and AI demand, because existing grids were not designed for decentralized renewables, bidirectional power flows, or fast EV charging. Current grid demand is embedded in regulation and industrial policy, which makes it less cyclical than the old China-construction-driven cycle. Electric vehicles use nearly three times the copper of conventional cars — motors, inverters, wiring harnesses, charging systems — and BMI forecasts EV copper demand of 2.2 million tons in 2030 versus 1.2 million in 2025, up from just 204,000 tons in 2020. Data centers are the concentrated surprise: CRU expects copper demand from data centers of about 260,000 tons in 2026, up from 78,000 in 2020 and exceeding 650,000 tons by 2030, with Wood Mackenzie estimating roughly a million tons of additional demand by 2030 — modest against a ~40-million-ton market, but concentrated and potentially disruptive, since a single hyperscale facility routinely deploys more than 2,000 tons of copper in busbars, cooling, and high-speed interconnects. Renewables add their share: more than 90% of new global power-generation capacity in 2025 came from solar and wind, power generation needs roughly 2 to 5 tonnes of copper per megawatt, and a kilometer of high-voltage underground cable contains more than 2.5 tons of copper. The big-picture forecasts put global demand at 28 million tons in 2025 rising toward 42 million by 2040, with S&P Global flagging a potential 10-million-ton supply gap without major investment — figures from commercial analysts that should be read as estimates, but the direction is consistent across sources.

Plumbing, HVAC, and electronics

Beyond the megatrends, copper is the working metal of the trades. Plumbing and HVAC run on copper tube, fittings, valves, and coils — and generate a constant scrap stream of cutoffs, pulled-out pipe, old water heaters, and replaced condensers. Electronics consume copper in circuit boards, connectors, and wiring; e-scrap is a real but lower-grade copper source that needs proper handling. Transportation beyond EVs — conventional vehicles, rail, ships — uses copper in wiring, motors, and radiators. Industrial machinery, appliances, motors, transformers, and generators round out the picture; motors and transformers are among the richest copper-bearing scrap items a seller will ever encounter. One watch item: record prices are driving substitution — aluminum and fiber-optic cable replacing copper in construction and manufacturing where copper is a large cost share. But substitution has limits, and tellingly, aluminum has largely been abandoned for data-center wiring, where performance wins. For sellers, the takeaway is straightforward: the sectors growing fastest — grid infrastructure, EVs, data centers — are all copper-intensive, which is structural support for long-term scrap value.
