Top 10 Aluminum Sheet Suppliers in Australia (2026)

20 Years Export Experience  •  1xxx–7xxx Alloy Series  •  Factory-Direct, No Middleman

Australia mines more bauxite and refines more alumina than any other country on earth, and still runs four primary aluminium smelters. It also used to roll its own aluminium sheet — Capral produced the country’s first locally rolled sheet in 1941, and Alcoa ran rolling mills at Point Henry and Yennora for half a century. Both closed permanently in 2014. Today, even Capral only extrudes domestically; flat sheet sold in Australia is imported and distributed rather than rolled here. The market splits between the country’s primary smelters and bauxite/alumina producers, established distributors supplying imported sheet and plate, and OEM manufacturers overseas who supply the flat-rolled product Australia no longer makes. Here’s how Australia’s leading aluminum mill product suppliers compare.

At a Glance

Australia’s Aluminum Mill Product Suppliers

1. Bell Bay Aluminium

Founded: 1955  |  Base: Bell Bay, Tasmania

Bell Bay was the first aluminium smelter built in the Southern Hemisphere, commissioned as a joint venture between the Commonwealth and Tasmanian governments to overcome wartime difficulties importing aluminium. Now owned by Rio Tinto, it holds Aluminium Stewardship Initiative certification, though it has reported financial losses in recent years and its long-term power contract with Hydro Tasmania was set to expire at the end of 2025.

2. Tomago Aluminium

Founded: 1983  |  Base: Tomago, New South Wales

Tomago is a joint venture between Rio Tinto, CSR, Norsk Hydro, and AMP, and ranks among the largest-capacity aluminium smelters in the country, producing primary aluminium ingot for both domestic and export markets.

3. Boyne Smelters

Founded: 1982  |  Base: Boyne Island, Queensland

Boyne Smelters, majority owned by Rio Tinto alongside YKK Aluminium, UACJ Corporation, and Southern Cross Aluminium, produces primary aluminium at a capacity of around 545,000 tonnes a year, drawing on Queensland’s Weipa bauxite deposits and the Gladstone alumina refinery.

4. Portland Aluminium

Founded: 1986  |  Base: Portland, Victoria

Portland Aluminium is Alcoa’s remaining primary smelter in Australia following the 2014 closure of its Point Henry operation, and continues to produce primary aluminium ingot for domestic and export markets.

5. Capral Aluminium

Founded: 1936  |  Base: National network, originally Granville, New South Wales

Capral traces back to the Australian Aluminium Company, and its Granville works rolled Australia’s first locally produced aluminium sheet on 10 June 1941. Today Capral is the only Australian company still locally producing aluminium extrusions, running eight presses across six sites, and also stocks and distributes sheet, plate, coil, and treadplate.

6. Alcoa of Australia

Base: Western Australia, with bauxite mines and three alumina refineries (Kwinana, Pinjarra, Wagerup)

Alcoa of Australia is 60% owned by Alcoa Inc. and 40% by Alumina Limited, operating two bauxite mines and three alumina refineries in Western Australia, making it one of the world’s largest alumina producers even though its Australian rolling and can-sheet operations closed permanently in 2014.

7. Austral Wright Metals

Founded: 1987, with non-ferrous manufacturing origins going back over 70 years  |  Base: Wetherill Park, NSW, with branches nationally

Austral Wright Metals formed from the merger of Austral Bronze Crane Copper and Wright and Company, and distributes aluminium sheet, plate, coil, bar, and tube alongside stainless steel, copper, and specialty alloys, serving industries from marine to mining.

8. Ullrich Aluminium

Base: Queensland-founded, with a national Australian network extending to New Zealand

Ullrich Aluminium supplies aluminium sheet, plate, and profiles as part of a broader metals range spanning Australia and New Zealand, operating under a shared distribution network across both markets.

9. Aluminium Industrial Solutions

Base: Australia

Aluminium Industrial Solutions stocks rolled aluminium sheet and extruded angle, channel, and tube in common grades such as 5005 and 5052, offering cut-to-size and folding services for fabrication, general purpose, marine, and architectural applications.

10. RSC

Type: OEM aluminum sheet & plate manufacturer  |  Experience: 20 years export experience  |  Base: Tianjin, China

RSC (Tianjin Ruishengchang) manufactures and exports aluminum sheet, plate, rod, tube, and coil directly from its own Tianjin facility, covering the 1xxx through 7xxx alloy series. Unlike the Australian companies above, it does not mine bauxite, smelt, or distribute locally — it produces to the buyer’s specification, with controlled thickness, improved flatness, stress-relieved options, and cut-to-size delivery, and exports to a growing list of markets including Brazil, Mexico, Turkey, Saudi Arabia, and the US.

Why the Country That Rolled Its Own Sheet Stopped in 2014

This is a different story from most countries on a list like this, because Australia didn’t fail to build rolling capacity — it built it, ran it for over 70 years, and then closed it. Capral’s Granville works rolled Australia’s first locally produced aluminium sheet in June 1941. Alcoa later ran its own rolling mills at Point Henry, Victoria, and Yennora, New South Wales, serving the domestic and Asian can-sheet markets for half a century, employing close to a thousand people between the smelter and the mills. In February 2014, Alcoa announced both rolling mills were no longer financially viable against global oversupply, and by December that year they were gone for good, along with roughly 200,000 tonnes a year of can-sheet capacity. Capral still extrudes locally — it’s the only Australian company that does — but the sheet, plate, and coil it stocks today is imported, not rolled at Granville anymore. Australia kept its smelters and its bauxite and alumina industry; it lost the rolling mills that turned that metal into flat product at home.

Sourcing Custom Aluminum Sheet Through an OEM Partner

If your project needs standard sheet in common alloys, Australia’s distributor network — Capral, Austral Wright, Ullrich, and others — covers that ground well. If you need a specific alloy, thickness, temper, or large bulk order that doesn’t sit in standard local stock, an OEM partner working from your exact specification is often the more direct route, since every flat-rolled sheet in the country has already been imported regardless of which distributor’s warehouse it sits in.

FAQ

Does Australia still manufacture its own aluminum sheet?
No, not since 2014. Alcoa permanently closed Australia’s last two aluminium rolling mills, at Point Henry and Yennora, that year. Australia continues to operate four primary aluminium smelters and a large bauxite and alumina industry, but there is no active flat-rolling mill producing sheet domestically.

What standard applies to aluminum sheet and plate used in Australia?
AS/NZS 1734:1997 is the joint Australia–New Zealand standard specifying requirements for wrought aluminium and aluminium alloy flat sheet, coiled sheet, and plate, covering chemical composition, mechanical properties, and dimensional tolerances. Buyers sourcing sheet from any supplier, domestic or OEM, should confirm the product is certified against this specification.

Is it cheaper to buy aluminum sheet from an Australian distributor or an OEM partner overseas?
It depends on the alloy, thickness, and order volume. Standard alloys in common thicknesses are readily available through Australian distributors for fast turnaround. Custom specifications, less common alloys, or large bulk orders are frequently more cost-effective sourced directly from an OEM mill.

Conclusion

Australia’s aluminum story runs from the world’s largest bauxite and alumina industry, through four primary smelters, to a rolling industry it built, ran for decades, and closed for good in 2014. If you need standard sheet or plate, the local distributors above are worth comparing directly. If you need a custom alloy, thickness, or bulk order at mill-direct pricing, an OEM partner is generally the more direct path.
