Copper and stainless steel both make a good medical ID bracelet. They look different, they need different care, and one of them contains magnets. The right choice is the one you will happily wear every single day.
Here is how the two compare, so you can pick with confidence.
The short answer
- Choose copper if you love a warm, bold look, don't mind a little care, and don't have a pacemaker, defibrillator (ICD) or other device that can be affected by magnets.
- Choose stainless steel if you want something you can wear in the shower, at the gym and in bed without thinking about it, if you prefer a lower price, or if you have an implanted heart device.

Look and feel
Copper has a warm, reddish glow that stands out, and it slowly darkens to a deeper brown with wear. Some people love that lived-in look. Our copper medical ID bracelets come in classic copper or black with a copper-colored inside, in classic or textured links.
Stainless steel stays bright and looks the same for years. It also comes in the widest range of styles, from slim chains and stretch bands to cuffs, plus black, gold and rose-gold finishes.
Everyday wear and water
A medical ID only helps if it is on you, so think about your day. Stainless steel handles water and sweat well, and many of our steel bracelets are marked waterproof on the product page, so you can leave them on in the shower or pool.
Copper does better kept dry. We recommend taking a copper bracelet off before showering or swimming, and wiping it dry after a workout. If you know you'll forget, steel is the easier choice.
Care and cleaning
Copper reacts with air, water and skin, so it gradually loses its shine. That is normal, and you can brighten classic copper again in a few minutes. Our guide on how to clean a copper bracelet shows gentle methods that are safe for the engraving.
Stainless steel only needs an occasional wipe with warm soapy water and a soft cloth.
Skin and allergies
Copper can leave a faint green mark on the skin. It comes from copper reacting with sweat, water or lotion, it isn't harmful, and it washes off with soap and water. Keeping your skin and the bracelet dry helps prevent it.
Surgical-grade stainless steel is on the Mayo Clinic's list of metals that aren't likely to cause allergic reactions, which makes it a common pick for sensitive skin. If you have a known metal allergy, ask your doctor which metals are safe for you.
Magnets, pacemakers and other devices
This is the most important difference. Our copper bracelets have built-in magnets, and magnets can affect pacemakers, implanted defibrillators and some other medical devices. If you have one of these, choose a non-magnetic bracelet such as stainless steel, and check with your doctor. Read more in can you wear a magnetic bracelet with a pacemaker?
Do copper or magnetic bracelets help with pain?
Many people wear copper simply because they like it. If you have heard it can ease joint pain, the evidence doesn't back that up: a University of York trial in people with rheumatoid arthritis found that copper bracelets and magnetic wrist straps had no real effect on pain, swelling or disease progression compared with a placebo. Choose copper for the look, and talk to your doctor about pain.
Engraving
Both metals include free custom engraving. On black copper, engraving shows in white for strong contrast. Whichever you choose, put the most important information first. Our guide to what to engrave on a medical ID has examples you can copy.
Still deciding?
Think about where you'll be when it matters most. If your ID needs to survive showers, swims and long days without a second thought, go with steel. If you want a statement piece and you're happy to take it off around water, copper is a great fit, as long as magnets are safe for you.
