At first glance, AUS-ION™ wrought iron pans and carbon steel pans look similar. Both are iron-based, can be seasoned and are celebrated as alternatives to synthetic non-stick. But the differences in material, construction and performance put AUS-ION™ in a different class altogether.
What Makes AUS-ION™ Different From Carbon Steel?
AUS-ION™ wrought iron outperforms carbon steel because of two things: the quality of the low-carbon wrought iron we use, and our patented one-piece construction.
It's no secret that our Aussie-made wrought iron pans outperform cast iron: they're lighter, more conductive, more energy-efficient, and even more durable. But they're also superior to carbon steel pans.
Every AUS-ION™ pan is precision-engineered in Sydney from a single solid sheet of thick Australian iron. No rivets. No welds. No joins. Just one seamless piece, built to last for centuries.
Because every pan is backed by a multi-century warranty, they're not just "long-lasting" — they're designed to be true heirlooms, passed down for generations.
To suit different cooks, we also offer two finishes: our factory-seasoned Quenched range, or our new Polished range (no seasoning required, with all the benefits of iron and the convenience of stainless steel).
How Does the Material Differ Between AUS-ION™ and Carbon Steel?
AUS-ION™ wrought iron pans are low carbon: 99.97% pure iron and just 0.03% carbon. That’s around 10–30 times less carbon than traditional carbon steel cookware on average (usually 0.4–1.0% carbon).
At 3mm thick (4mm for our heavy-duty range), AUS-ION™ is tougher, more conductive, and more durable than standard cookware. Its solid wrought-iron construction distributes heat evenly and resists warping, even under high heat.
By contrast, carbon steel pans are pressed from thinner sheets of higher-carbon steel (typically 1.5–2mm). This higher carbon content reduces conductivity and creates hot spots. Combined with thinner gauge steel, it makes carbon steel more prone to warping or distortion over time.

How Does Construction Differ Between AUS-ION™ and Carbon Steel?
AUS-ION™ pans are formed from a single solid sheet of wrought iron with no coatings, rivets, welds or joins: carbon steel pans almost always rely on riveted handles fixed to a pressed steel body.
There's nothing on an AUS-ION™ pan to trap grime, loosen, or fail. This patented one-piece design is stronger, simpler, and so durable that we back every pan with a multi-century warranty.
Traditional carbon steel cookware's rivets create weak points that loosen over time and eventually compromise the entire pan, often sending it to landfill much sooner than expected.
Which Heats Better: AUS-ION™ or Carbon Steel?
‘’Not only does our highly conductive, solid 3mm thick wrought iron heat faster and more evenly than cast iron - our pans also hold that heat very well and can handle searing a big steak without cooling instantly like thinner carbon steel pans’’.
Mark Henry (Solidteknics founder and engineer).
Our pans are more conductive than traditional carbon steel pans because they typically contain 10–30 times less carbon. Higher carbon reduces thermal conductivity, which is why carbon steel can heat unevenly and cool quickly. Thinner walls (material thickness) can add to the problem, making it often harder for carbon steel to hold searing temperatures during cooking.
Which Pan Is Ready to Cook Straight Out of the Box?
Choose our AUS-ION™ Quenched factory-seasoned range or our new AUS-ION™ Polished range, which doesn’t require seasoning at all. Either way, you can start cooking straight out of the box!
Carbon steel pans, on the other hand, usually arrive coated in beeswax. Often requiring scrubbing and a full seasoning process before first use.

Which Has Cooler, More Ergonomic Handles?
Our patented handles are part of the one-piece body. AUS-ION™ wrought iron pans have long, ergonomic handles that have specially designed vents to dissipate the heat. This means the handles stay cool enough to hold and maneuver when cooking on the stovetop.
Carbon steel cookware handles are usually flat strips riveted on. They heat up quickly, and loosen with repeated use. A design destined to quickly add to landfills. 
Where Is AUS-ION™ Made?
Our pans are made in Sydney, Australia: Solidteknics is the only production cookware manufacturer in Australia, while most other cookware is made offshore.
By choosing Solidteknics, you're supporting ethical, local manufacturing and skilled Australian jobs.
Is AUS-ION™ Wrought Iron Healthier Than Carbon Steel?
Like cast iron, carbon steel cookware is often made from recycled steel scrap (e.g. car parts with other materials attached!) and can therefore contain a mix of heavy metals, leading to contamination and leaching into foods that can have negative health impacts. The quality you get depends on the mill and the refining process.
Our wrought iron cookware is made from 99.97% clean Australian iron, and is free from heavy metals and coatings.
Carbon steel pans may last decades with care, but AUS-ION™ wrought iron is built for centuries. Stronger, more conductive, seamless, healthy and Australian-made, it’s the clear choice if you want cookware that truly lasts.

FAQ
Where is AUS-ION™ cookware made? AUS-ION™ is precision-engineered in Sydney, Australia. Solidteknics is the only production cookware manufacturer in Australia.
Is AUS-ION™ the same as carbon steel? No. AUS-ION™ is a low-carbon wrought iron (0.03% carbon), while carbon steel typically contains far more carbon. The lower carbon content gives AUS-ION™ better conductivity and durability.
Why doesn't AUS-ION™ have riveted handles? Every AUS-ION™ pan is engineered from a single sheet of wrought iron, including the handle, using patented one-piece construction. This removes rivets and welds entirely, which are a common failure point in carbon steel cookware.
