If you’ve got some old cast iron lying around maybe an old BBQ plate, a broken radiator, a bath, or even a chunk of plumbing, you might be wondering if it’s worth anything. Can you actually make some money from it? Is it worth dragging it all the way to a scrap yard?
In Sydney, cast iron is a common material found in household waste, construction debris, and machinery. While it’s not as valuable as metals like copper or brass, it still holds value in the scrap world, especially when sold in large amounts or in clean condition.
Let’s dive into how much cast iron is worth per kilo in Sydney, whether it’s considered valuable, and if your local scrap yard will take it.
What is Cast Iron Worth Per Kilo in Sydney (as of 2025)?
The value of scrap cast iron can vary depending on a few key factors, mainly the condition (clean vs. mixed), quantity, and current market demand. Here’s a general price range based on recent industry rates:
| Cast Iron Condition | Approximate Price per Kilo (AUD) |
| Clean cast iron (no attachments or contamination) | $0.15 – $0.30 |
| Mixed or dirty cast iron (with rubber, bolts, oil) | $0.08 – $0.15 |
If your cast iron is in good condition, free from contaminants like oil, plastic, or attached metal parts, you can expect to get closer to the higher end of the price range. On the other hand, if it’s mixed with other materials or heavily rusted, scrap yards may offer less or even classify it as general ferrous scrap.
Prices can also change weekly depending on global metal markets, so it’s smart to call around and compare rates before making a trip.
Is Cast Iron Valuable as Scrap?
Yes, But with a Few Considerations.
Cast iron isn’t the most valuable metal out there, especially compared to non-ferrous metals like copper, aluminium, or brass. However, it does hold value because of its weight and iron content.
Why It’s Valuable:
- Heavy weight: Even small objects can weigh a lot, so you’re getting more per item than lighter metals.
- High recyclability: It can be melted down and reused for a range of industrial and construction purposes.
- Consistent demand: Iron and steel recycling is a core part of the metal industry.
But Keep in Mind:
- Low per-kilo rate: It doesn’t fetch a high price per kilogram.
- Transportation cost: It’s bulky and heavy, which can eat into your profits if you need to rent a trailer or travel far.
- Condition matters: The cleaner the metal, the better the price. Dirty or contaminated cast iron may be downgraded.
So yes, cast iron is definitely worth something, especially if you’ve got a large quantity or heavy items. But it’s not a get-rich-quick material, you’ll make more with volume.
Do Scrap Yards in Sydney Accept Cast Iron?
Absolutely. Almost all scrap yards and metal recycling centres in Sydney accept cast iron. It typically falls under the “ferrous metal” category, or more specifically, “heavy iron.”
Here’s how most yards deal with it:
- Yes, they take it: Most scrap yards will gladly accept cast iron, especially in larger pieces or bulk loads.
- Better if sorted: If you separate cast iron from other materials (like stainless steel, brass, or copper), you’re more likely to get the correct rate.
- Cleanliness helps: Items like old bathtubs, grates, or radiators should be cleaned of oil, rubber, or plastic before drop-off.
- ID may be required: Many yards require ID when scrapping metals to comply with local regulations and prevent theft.
Whether it’s a busted manhole cover or an old iron pan, it’s worth calling your local yard to confirm their requirements. Some even offer pick-up services for heavy loads.
How to Get the Best Price for Your Cast Iron
If you’re serious about scrapping cast iron, here are a few tips to make sure you get the most value:
- Sort It: Keep your cast iron separate from other metals and materials to avoid “mixed scrap” pricing.
- Clean It: Remove any non-metal components like rubber, wood, or plastic.
- Weigh It First: Knowing how much you’re taking in can help avoid being lowballed.
- Shop Around: Different scrap yards offer different rates, even in the same city. Make a few calls.
- Bulk Up: The more weight you bring in, the more it’s worth your time (and gas money).
Final Thoughts
Cast iron might not make you rich overnight, but it’s definitely not worthless. In Sydney, clean cast iron can fetch between $0.15 to $0.30 per kilogram, which adds up quickly with heavy items. Scrap metal yards in Sydney absolutely do accept it, and they prefer it clean and sorted.
If you’ve got some lying around, why not recycle it? It’s good for the environment and your wallet, even if just a little.
