Introduction: Copper as the Metal of Civilisation and the Future
Copper has always been more than a metal. It was the first element humans shaped into tools, coins, and trade goods. It protected the ships of empires, carried the first sparks of electricity, and now powers the green revolution.
From the price of copper per kg for manufacturers to the growing appeal of copper ingots for collectors and investors, copper is both an industrial backbone and precious store of wealth.
At Ingots We Trust, we see copper not just as a commodity, but as civilisation’s strongest elemental ally – one that stands proudly alongside gold and silver.
How Much Copper Do We Use? Weights Across Modern Applications
Copper in Electric Vehicles (EVs)
- 50–80 kg of copper per EV (depending on model and battery size)
- 25–30 kg in hybrid vehicles
- 180–370 kg in electric buses
- 0.7 kg of copper per kW of charging station capacity
Every EV on the road is a copper vehicle first.
Copper in Renewable Energy
- Wind Turbines: 2–5 tonnes of copper per utility-scale turbine
- Solar Power: ~5 kg of copper per kW installed
- Residential (5kW): ~25–30 kg
- Large-scale farms: several tonnes
- Energy Storage: 40–60 kg of copper per MWh of battery capacity
- Smart Grids: kilometres of copper cabling for transmission
Every megawatt of clean power is built on copper.
Copper in Homes, Cities, and Infrastructure
- 200-400 kg of copper in the average home (wiring, plumbing, HVAC)
- Several tonnes in hospitals and office buildings
- 2-3 tonnes of copper per kilometre of electrified railway track
- 3-5 kg in every 5G telecom tower
Copper is the silent force wiring modern life.
Copper in Electronics & Medical Equipment
- Smartphone: ~15-20 grams of copper
- Laptop: ~40-50 grams
- Data Centres: 2-5 tonnes per facility
- MRI Machine: ~900 kg of copper each
- Hospital surfaces: antimicrobial copper reduces infection spread
Copper not only powers devices — it protects human life.
Copper in Aviation, Shipping, and Transport
- Aircraft: ~2 tonnes of copper wiring per plane
- Ships: up to 200 tonnes of copper in cables, motors, and systems
- High-speed trains: 8-10 tonnes each
Copper keeps global trade and travel moving.
Copper’s Key Properties: Why It’s Invaluable
- Electrical Conductivity: Second only to silver, but far more abundant and affordable.
- Thermal Conductivity: Transfers heat efficiently — critical in engines and electronics.
- Corrosion Resistance: Essential for plumbing, naval ships, and renewable infrastructure.
- Antimicrobial: Copper surfaces fight infections in hospitals and homes.
- Recyclability: 100% recyclable without loss of quality — a truly eternal metal.
Copper, Gold, and Silver: The Indispensable Partnership
Gold and silver shine as stores of wealth. But without copper, they cannot scale their impact:
- Electronics: Gold and silver connectors rely on copper wiring to carry energy affordably.
- Money Systems: Gold and silver coins were historically backed by copper in circulation.
- Green Technology: Silver in solar cells and gold in high-tech devices depend on copper’s wiring and conductivity.
Gold and silver may be the crown and the jewels, but copper is the throne they rest upon.
Investing in Copper: A Store of Wealth for the Future
Rising copper prices per kg are not just industrial metrics – they are signals of copper’s future power.
- Accessible: Unlike gold, copper is affordable for new investors.
- Essential: EVs, renewables, and smart grids guarantee long-term demand.
- Tangible: Owning copper ingots like The Precious™ (1kg) and The Behemoth™ (5kg) means holding history and future in your hands.
- Certified: Every Ingots We Trust bar is KPS™️ XRF and Sigma assayed and certified at 24K Cu (.9999) – purity guaranteed.
