Context
- Copper prices have surged to record levels, with the London Metal Exchange (LME) copper touching an all-time high of $14,779 per tonne, increasing input costs for electric vehicles (EVs), consumer electronics, electrical wires and engineering goods.
Why are Copper Prices Rising?
- LME Benchmark Pressure: Physical contracts worldwide index directly to London Metal Exchange (LME) prices, which spiked as exchange inventories dwindled.
- Mine Supply Deficits: Operational disruptions in top producers like Chile cut concentrate output, creating an upstream supply squeeze.
- Tariff Stockpiling & Arbitrage: Front-loaded buying by US importers ahead of anticipated tariffs diverted global flows and depleted spot warehouse stocks.
- Clean-Tech & AI Demand: Rapid rollout of copper-heavy EVs, power grids, and AI data centres created structural, long-term consumption pressure.
Sectors Affected – Cost Pressure Chain
- Electric Vehicles (EVs): Higher input costs for wiring and electric motors.
- Consumer gadgets and appliances: Rising component costs.
- Electric wires and engineering goods: Direct raw material cost increase.
- Indian industry imports ~85% of its copper requirements, making India particularly vulnerable to global price cascades.
Aluminium as a Substitute
- Industry (EVIA — Electric Vehicle Industry Alliance) suggests aluminium is emerging as an alternative:
- 61% of copper’s electrical conductivity.
- 6× larger cross-sectional area required for the same electrical load.
- Aluminium conductors therefore need to be larger in size to carry the same electrical load.
- Copper remains difficult to replace in several applications requiring compactness and high conductivity.
Impact on Indian Industries
- India imports around 85% of its copper requirements, making domestic industries vulnerable to global price fluctuations.
- Higher copper prices can raise input and production costs for electrical goods, engineering products, EVs and consumer electronics.
- The impact is greater in sectors where copper has limited substitutes, potentially putting pressure on manufacturers’ profit margins.

Q. With reference to copper and its industrial use, consider the following statements:
1. Electric vehicles utilize significantly less copper compared to conventional internal combustion engine vehicles due to battery miniaturization.
2. India relies on imports for more than 80% of its domestic copper requirements.
3. Aluminium possesses higher electrical conductivity than copper, making it the preferred substitute in compact electric vehicle motors.
Which of the statements given above is/are correct?
(a) 2 only
(b) 1 and 2 only
(c) 2 and 3 only
(d) 1, 2 and 3
Answer: (a) 2 only
Explanation:
• Statement 1 is incorrect: Electric vehicles (EVs) require approximately 3 to 4 times more copper than traditional combustion vehicles due to electric motors, battery packs, inverters, and charging harnesses.
• Statement 2 is correct: India is heavily import-dependent, importing around 85% of its total copper requirements.
• Statement 3 is incorrect: Aluminium has only about 61% of the electrical conductivity of copper; an aluminium conductor must be roughly 1.6 times larger in cross-section to transmit the same electrical load, limiting its feasibility in tight, high-heat EV motors.
