7 Metals That Don’t Rust: Tough Stuff That Lasts
6 Jun 2025
Rust is metal’s worst enemy. One minute you’ve got a solid bit of kit, the next it’s flaking, cracking and looking like it’s been through a storm. Whether you’re on-site, in the shed or setting up a new project, rust is the one thing you don’t want showing up.
The good news? Some metals don’t rust at all. Others put up a solid fight with coatings and clever chemistry. In this guide, we’ll break down the metals that don’t rust – or at least give rust a proper run for its money.
We’ll also clear up questions like:
- Does stainless steel rust?
- Can aluminium rust?
- What metal doesn’t tarnish or corrode?
- And what’s the best metal for outdoor use?
Article in brief
Rust only affects metals with iron – like carbon or mild steel.
Aluminium, copper, brass, bronze, stainless steel and titanium don’t rust.
Galvanised steel resists rust thanks to its zinc coating.
Pick your metal based on the environment, finish and strength you need.
We’ve got rust-resistant metals ready to go – cut to size and delivered fast.

What is rust, exactly?
Rust happens when iron meets oxygen and moisture – and the result is iron oxide. That’s the reddish-brown stuff you see peeling off old fences, tools or forgotten machinery. It weakens metal, wrecks the look and makes your job harder in the long run.
Only metals with iron in them can actually rust – so materials like mild steel and carbon steel are most at risk. Will carbon steel rust? Absolutely – unless it’s treated, painted or galvanised. Even alloy steel can rust if it’s not properly protected.
But rust isn’t the only worry. Other metals might not rust, but they can still tarnish or corrode in salty, damp or chemical-heavy environments. So it’s not just about skipping rust – you want to select the right material for your build.

Metals that don't rust
Here’s your go-to list of rust-free metals and why they’re worth a spot in your next job.
1. Aluminium
Does aluminium rust? Nope – it’s completely iron-free. But it does form a tough oxide layer when exposed to air. And that’s a good thing. This oxide film actually protects it from further corrosion, meaning your aluminium keeps its strength and finish for longer.
Lightweight, low-maintenance and available in everything from flat bars to tubes to sheets – it’s ideal for signage, fencing, kitchen units, cladding and more.
Take a look at our full range of aluminium products.
2. Copper
Can copper rust? Not a chance. Like aluminium, it’s a pure metal and contains no iron, so rusting is off the table.
What it does do is slowly oxidise and develop a green patina over time – especially outdoors. This isn’t corrosion in the damaging sense – it actually helps preserve the surface underneath. You’ll see copper in roofing, plumbing and eye-catching design pieces that are made to last.
If you’re looking for copper sheet, The Metal Store has you covered.
3. Brass
Does brass rust? No. Can brass rust? Still no. Brass is made from copper and zinc – both non-rusting metals. It’s also strong, smooth and holds up well in tricky environments.
You’ll find it in fittings, musical instruments, marine gear and decorative work. And while brass might tarnish a little over time, it won’t flake or weaken like rusted steel.
You’ll find brass tubes, angles, bars and sheets in our collection.
4. Bronze
Like brass, bronze is another copper alloy – this time mixed with tin. And just like brass, bronze doesn’t rust. Why? No iron. It’s corrosion-resistant, durable and looks the part too.
You’ll often see bronze used in sculptures, tools, outdoor fittings and marine hardware. It can occasionally suffer from “bronze disease” – a rare form of corrosion in salty conditions – but for most jobs, it’s rock solid. So if you’re asking “does bronze rust?” – the answer’s a confident no.
5. Stainless steel
Now, this one gets asked a lot – Does stainless steel rust? Technically, it can – but not in the same way as mild or carbon steel. Stainless steel is an iron alloy, but it’s mixed with chromium, which forms a protective oxide layer. This barrier blocks rust from forming on the surface.
It’s one of the most rust-resistant metals you can get. Kitchens, bathrooms, balustrades, bike frames, tools – stainless steel is everywhere. It’s even a go-to for coastal builds when you choose the right grade.
Wondering “does stainless steel rust outside?” or “is stainless steel rust proof?” With the right maintenance and grade, it’s as rust-resistant as it gets.
If this is your metal of choice, we have a selection of stainless steel products to choose from.
6. Titanium
If rust was a sport, titanium would be undefeated. It doesn’t rust, corrode or even flinch under pressure. It’s lighter than steel, stronger than aluminium and stands up to saltwater, chemicals and heat.
That’s why it’s the go-to in aerospace, marine gear and high-end engineering. It’s not cheap – but for performance, it’s top tier.
And no, titanium does not rust. Full stop.
7. Galvanised steel
Here’s the real question – Can galvanised steel rust? Yes – but only if the zinc coating gets damaged or wears down over time.
Galvanised steel is regular steel coated with zinc to stop water and oxygen from reaching the metal underneath. This makes it rust-resistant – not rust-proof. Still, it’s one of the best-value options if you want solid protection without the cost of stainless.
Perfect for fencing, scaffolding, walkways and handrails. It’s strong, affordable and holds up well outdoors – as long as that coating stays intact.
Whatever products you need, our galvanised steel collection covers all bases.

How to choose the right metal for the job
It’s not just about picking any old rust-proof metal. It’s about what works best for your environment and build:
- Need rust resistance on a budget? Galvanised steel is your mate.
- Want low-maintenance outdoor use? Go aluminium or stainless.
- Need max strength with no rust? Titanium or bronze steps in.
- Want a clean, shiny finish? Stainless or brass looks great and lasts.
Also, don’t forget the environment. Saltwater, chemicals and moisture all mess with metal in different ways. Choose your gear accordingly.
