Aluminium Scrap Prices: What Determines the Value?

Understanding Aluminium Scrap Prices in Australia

Aluminium scrap is one of the most actively traded non-ferrous metals in Australia, and its pricing moves differently from copper, brass, or steel. Because aluminium is lightweight, infinitely recyclable, and widely used in packaging, transport, and construction, the aluminium scrap market attracts a broad audience ranging from large industrial recyclers to households with a handful of old window frames. If you are a scrap buyer, seller, dealer, or recycler, understanding what actually drives the value of this metal is the single most important factor in protecting your margin.

Below is a clear, practical guide to the factors that determine aluminium scrap prices in Australia, along with preparation tips, market insight, and answers to common questions.

What Determines the Value of Aluminium Scrap?

Aluminium scrap prices are not a single fixed number. They are the result of several overlapping factors that change daily or weekly. Knowing each factor helps you read the market, time your sales or purchases, and avoid leaving money on the table.

1. London Metal Exchange (LME) Aluminium Price

The base reference for nearly every local quote is the LME aluminium price in US dollars per tonne. Australian scrap yards adjust this benchmark for the AUD/USD exchange rate, local logistics, and demand. When the LME rises, scrap yards typically lift their buy prices within days.

2. Scrap Form and Cleanliness

Form matters as much as weight. Clean, uncontaminated aluminium such as 6063 extrusion off-cuts, 6061 plate, or clean UBC (used beverage cans) commands premium pricing. Material mixed with steel, plastic, paint, rubber, or insulation must be processed further, which reduces the price a yard is willing to pay.

3. Scrap Trading Volume and Supply Flow

Scrap trading in Australia is seasonal. Summer construction booms push extrusion and sheet volumes higher, while post-harvest periods often bring a surge in old farm and irrigation aluminium. When local supply outstrips mill demand, yards may widen their buy/sell spread. When supply tightens, prices firm up quickly.

4. Alloy Type and Traceability

Different alloys behave differently when remelted. Extrusion grades (6060, 6063), casting grades (A356, LM6), and aerospace plate (7075) each have distinct recovery rates and end-market demand. Traceable, alloy-segregated loads can earn a documented premium, particularly when exporting to Asian smelters.

3. Freight, Container Rates, and Export Demand

Most Australian aluminium scrap eventually heads offshore to smelters in South Korea, Japan, India, and Southeast Asia. Container freight, port handling fees, and shipping schedules all influence what a yard can pay. When export demand is strong, domestic prices rise with it.

5. Energy Costs and Smelter Capacity

Aluminium smelting is extremely energy-intensive. When Australian or regional electricity prices rise, secondary smelters tighten their input prices to protect margins. Conversely, smelter outages or maintenance shutdowns can pull scrap prices downward temporarily.

How to Prepare Aluminium Scrap for the Best Price

Preparation is where most sellers lose value. Clean, sorted aluminium can be worth significantly more per kilogram than mixed or contaminated loads. Use the checklist below before you load a truck or trailer.

• Sort by alloy and form: Keep extrusion, sheet, UBC, and cast separate. Mixed loads are penalised.
• Remove attachments: Strip steel brackets, screws, rubber seals, plastic caps, and glass from window frames before weighing in.
• Cut large items down: Most yards prefer pieces under 1.5 metres for safe handling and container loading.
• Keep UBC dry and uncrushed where possible: Some buyers pay a small premium for loose, clean cans.
• Avoid contamination: A single piece of copper in a tonne of aluminium can downgrade the whole load.
• Weigh accurately: Use a calibrated weighbridge and keep scale tickets for your records.

Pricing Benchmarks and How to Compare Offers

Aluminium scrap is typically quoted in Australian dollars per kilogram or per tonne, depending on the size of the deal. Common reference categories include:

• Clean extrusion (6063): Often the highest-paying mainstream grade.
• Clean sheet and turnings: Slightly below extrusion, depending on oil content.
• UBC (used beverage cans): Priced lower per kilo but available in large volumes.
• Cast aluminium (e.g., wheels, manifolds): Mid-range, with premiums for low-iron clean cast.
• Aluminium radiators and wheels: Specialty items that may carry premiums if cleaned and sorted.

Prices fluctuate weekly, sometimes daily. Rather than relying on a single phone call, compare live rates using the ScrapTrade Australia scrap calculator, which aggregates current yard pricing across states. This gives you a real benchmark before you commit to a buyer or accept a sell offer.

Common Mistakes That Reduce Aluminium Scrap Value

The cheapest aluminium scrap to handle is clean aluminium scrap. Contamination is the single fastest way to cut your price.

• Mixing aluminium with steel or copper in the same bin.
• Selling oily or greasy turnings without draining or bailing.
• Leaving glass in window frames or rubber on radiator hoses.
• Accepting the first quote without comparing two or three yards.
• Selling during a quiet demand week when yards are overstocked.

Frequently Asked Questions About Aluminium Scrap

What is the current aluminium scrap price in Australia?

Prices change frequently based on the LME, exchange rates, and local demand. For an up-to-date figure, check the ScrapTrade scrap calculator, which reflects current market rates across Australian states.

Which aluminium alloy pays the most per kilo?

Clean 6063 extrusion generally commands the highest mainstream price. Aerospace grades such as 7075 can pay more, but they are less common and require verified traceability.

Is it worth selling small quantities of aluminium?

Yes, but weigh up transport costs. A bag of cans may only be worth a few dollars, whereas a boot-load of clean extrusion is usually worth the trip. Many yards set minimum load thresholds for premium pricing.

Do scrap yards pay more for sorted aluminium?

Almost always. Sorted, segregated loads save the yard labour and processing time, and a portion of that saving is passed back to the seller in the form of a higher per-kilogram price.

How often do aluminium scrap prices change?

Major yards review prices weekly, and some adjust mid-week when the LME moves sharply. If you are trading in volume, monitor the LME and local indicators regularly.
