Our Craft

Why hasn't anyone made metal cases?

Good question. We wondered that too. Turns out there are a few reasons...

Raw metal blocks signal

Pure metal can create what’s known as a Faraday cage, blocking your phone signal, wireless charging, and NFC.

It corrodes quickly

Pure metals oxidize and corrode too much. We’ve all seen the Statue of Liberty. While it looks beautiful from afar, the up-close surface isn't something you want to touch all day.

It's heavy

Your phone is heavy enough as is. We want to provide all the benefits of metal, without weighing you down.

Ancient metal, 
modern magic

Our proprietary alloy technology is over 70% metal, retaining the metallic qualities you want while making an awesome material for a phone case.

Removing conductivity

We created a matrix that suspends metal particles just far enough away from each other to eliminate conductivity while preserving antimicrobial efficacy. The lack of conductivity means that our alloys won’t block phone signal, wireless charging, or NFC!

Patina

Our alloys will age in a way that is similar to pure metal, without the unwanted effects. They will darken over time as they are exposed to fingers, air, and water, but will never turn green or stain.

Weight

With our proprietary technology, we're able to apply a durable microthin layer to every case. That means we’re able to provide the properties of metal, without the weight.

A case that's
uniquely yours

Like linen or leather, copper looks better with age. Your case will develop a patina as you use it — this isn’t a flaw or defect, it enhances the aesthetic without diminishing any of your case’s functionality. Each patina will develop slightly differently — making your case uniquely yours.

Frequently Asked Questions

What's an Alloi case made of?

We use the best materials possible to optimize the performance of our case. There are four layers: (1) a seismic geometric inner plate for shock absorption, (2) a cushioned TPU liner to hold your phone in place, (3) a tough polycarbonate outer shell, and (4) our proprietary copper nanocoating. Plus, the buttons are coated!

How protective are your cases?

Our cases are designed to withstand the worst of everyday wear and tear, and it has the results to back it up. Don't believe us? We tried to break it, then ran over it with a car. It survived.

Do Alloi cases interfere with phone signal, contactless pay, and wireless charging?  

Our design does not interfere with phone signal or contactless pay, and our case works with most wireless chargers.

Does it deteriorate over time?

While pure copper does oxidize and tarnish over time, our composite technology is resistant to these effects. It will patina, or slightly darken, over time. However, unlike traditional “Statue of Liberty” oxidation, this patina is not green and will not stain your hands or clothes. You do not need to keep it polished to keep it working, but we do support keeping it in good shape. Clean it often using a soft cloth — see "How do I care for my patina?" below for more.

What is your shipping/returns policy?

We offer rapid fulfillment, with guaranteed shipping within 2 business days of ordering. Once we ship, the average delivery time is 2-3 days for domestic orders and 2-3 weeks for international orders (NOTE: Due to COVID-19, shipping times may vary and are subject to unexpected delays). We are currently unable to offer returns, but offer a flexible replacements and refund policy if you are not satisfied with your case.

Does copper make the case smell?

Nope! Copper is actually odorless. The smell we associate with pennies comes from copper's reaction with oils and other substances on your hands. Out technology is engineered to eliminate this reaction. Fun fact: pennies are only 2.5% copper! They stink.

Designed, not made

Everything we use is intentionally selected for performance and aesthetics. You won't find products like this anywhere else.
