This snapshot uses the latest shared monthly observation and an initial five-year window, shortened when the common archive is smaller. It stays on that labelled basis when you explore another chart range above.
World Bank Pink Sheet. Monthly averages; not executable transaction quotes.
From 2021-08 to 2026-08, the shared monthly window changed +52.89% for Copper and +24.89% for Aluminium. The endpoint difference was 28.00 index points. This describes the selected historical window, not a forecast.
+52.89% from 2021-08 to 2026-08.
+24.89% over the same observation dates.
Copper is an industrial benchmark normally quoted per metric tonne. Prices depend on grade, location and delivery; refined copper prices are not scrap-yard offers.
Aluminium is traded in primary and alloy forms. Regional physical premiums, power costs and transport can make delivered prices differ from a headline benchmark.
Use the standalone copper price history and aluminium price history to inspect each source series in its original unit. The commodity price archive provides frequency controls and individual CSV downloads.
Both source series use USD per tonne. Matching units make the nominal figures easier to read together, but Copper and Aluminium still have separate specifications and markets.
Both sit in industrial metals, yet their stated uses differ: Copper — Power cables · Construction · Electric motors; Aluminium — Transport · Packaging · Construction. A shared category does not make the products substitutes.
The overlapping selectable frequencies are monthly and yearly. Daily comparison is offered only when both stored series have daily coverage; otherwise monthly observations provide the common basis.
These subject–relationship–object facts keep the two commodities, their units and the chart method separate.
| Subject | Relationship | Object | Why it matters |
|---|---|---|---|
| Copper | is published in | USD per tonne | Read copper in its original source unit before converting it. |
| Aluminium | is published in | USD per tonne | Read aluminium in its original source unit before converting it. |
| Copper | is used in | Power cables · Construction · Electric motors | These uses provide context for copper demand; they do not explain every price move. |
| Aluminium | is used in | Transport · Packaging · Construction | These uses provide context for aluminium demand; they do not explain every price move. |
| Copper versus Aluminium | is aligned on | 61 shared monthly observations from 2021-08 through 2026-08 | The chart compares matching dates and gives both series a starting index of 100. |
The copper reference is a refined-metal benchmark, normally published per metric tonne. It is a starting point for understanding broad movements rather than a quote for a cable reel, a fabricated component or a mixed scrap load. Converting the price to kilograms changes the mass basis but does not change the material specification.
Delivery and quality: Regional availability, grade, transport and delivery timing affect physical terms. Compare equivalent material and locations before interpreting a price difference.
An aluminium reference does not include every cost of producing a sheet, extrusion or finished part. Primary metal, alloy material and fabricated products have distinct specifications. The table preserves the source unit so that a per-kilogram conversion is not mistaken for a change in grade.
Transport and packaging: Transport, packaging and construction use aluminium in different forms. Product mix can change demand for particular alloys or shapes.
Copper and aluminium are major industrial metals used in electrical, transport and construction applications. Their different conductivity, density, fabrication and specification requirements make the comparison useful for input-cost context, not direct substitution arithmetic.
Both references use USD per metric tonne, but equal mass does not provide equal electrical or structural performance. Engineering requirements determine how much material a product needs.
Regional premiums, alloy choice, fabrication, transport and availability can change the price of cable, sheet or extrusions relative to the refined reference.
Both metals respond to manufacturing and construction conditions, but their product mixes differ. Similar indexed movement does not prove a single shared cause.
From 2021-08 to 2026-08, the shared monthly window changed +52.89% for Copper and +24.89% for Aluminium. The endpoint difference was 28.00 index points. This describes the selected historical window, not a forecast. Change the chart range to test another starting point; the labelled monthly snapshot keeps its own initial window.
The overlapping selectable frequencies are monthly and yearly. Daily comparison is offered only when both stored series have daily coverage; otherwise monthly observations provide the common basis.
Both source series use USD per tonne. Matching units make the nominal figures easier to read together, but Copper and Aluminium still have separate specifications and markets. The indexed view answers how each stored reference moved from a shared starting date; it does not calculate a transaction return.
Both sit in industrial metals, yet their stated uses differ: Copper — Power cables · Construction · Electric motors; Aluminium — Transport · Packaging · Construction. A shared category does not make the products substitutes. Also confirm the observation date, grade or purity, delivery terms and costs that apply to the actual product.
