Carbon Fiber vs. Aramid Phone Cases: Which is Best for Your iPhone?

Phone cases serve the important purpose of protecting our phones from scratches and damage, but a top-notch phone case can also elevate the overall user experience and style up the look of our phones. Among the myriad of options, two materials often stand out for their exceptional durability and premium feel: carbon fiber and aramid fiber. 

Due to the similar appearance and the misleading of many manufacturers, a lot of users are confusing carbon phone cases with aramid phone cases. In fact, they are absolutely two different materials.

In this blog post, we'll help you figure out the difference between carbon fiber and aramid fiber, and which one should be the ideal material for phone cases.

What Is Carbon Fiber?

Carbon fiber is a high-strength material made from thin strands of carbon atoms. It is known for its excellent strength-to-weight ratio -- double rigid and five times stronger than steel, making it a popular choice in aerospace, automotive, and sports equipment industries.

What Is Aramid Fiber?

Aramid fiber is a synthetic material made from long chains of polymer molecules. It is known for its exceptional strength and heat resistance, making it a popular choice in the military and aerospace industries. Aramid fibers also have excellent resistance to wear, impact damage, and non-conductive properties, making it a perfect material for phone cases.

Here is a table that can help you have basic knowledge about the difference between the two materials.
Carbon Fiber Aramid Fiber
Material Pure carbon fiber Man-made strong synthetic fiber
Strength Low strength High strength
Resistance to abrasion Good Better
Resistance to solvents Good Better
Conductivity Conductive Non-conductive
Melting point High No melting point
Flammability High Low
Color Black Light golden color
Stainability Can't be colored Can be colored

Carbon Fiber vs. Aramid Fiber: Which Is Better for Phone Cases?

Stiffness & Flexibility

Carbon fiber is extremely strong in tension and compression and is by far the stiffest of the fibers, but it's brittle. The carbon fibers are not as tough as aramid fibers, and a carbon phone case will be also brittle of course. At that extent, an aramid fiber phone case is more tough and flexible.

Electrical Conductivity

Because of its electrical conductivity, carbon fiber phone case will reflect or even offset the electromagnetic wave sent from the phone and reduce the signal by 40%-60% on average. This is why carbon fiber is not suitable for making phone cases.

Instead, aramid fiber is an excellent nonconductor. So phone cases made from this material will not cause interruptions to WiFi, GPS, or any signals from your phone.

Carbon fiber is always black and by itself it cannot be dyed. Aramid fiber, on the other hand, is light golden in natural state and can be colored. This is the easiest way to tell whether it is a carbon fiber phone case or an aramid fiber phone case.

Additionally, aramid fiber phone case remains the stylish design and elegance of the original phone and that will give you a 3D silky touch experience you never feel before. Thanks to the special characteristic of aramid fiber, the phone case made with this material boasts extraordinary scratch resistance and discoloration over years of use.

Best iPhone 15 Case

Since the electrical conductivity of carbon fiber results in signal loss, it is not an ideal material for phone case. On the contrary, an aramid fiber phone case is a better alternative. PITAKA MagEZ Case 4 for iPhone 15, crafted from aramid fiber, will be highly recommended.

At a mere 0.95mm thin and weighing only 17g, this super light iPhone 15 case protects your iPhone 15 without compromising its slim profile. The use of aramid fiber not only ensures exceptional strength but also adds unique 3D textured patterns, accentuating the visual appeal of your device and offering a skin-friendly touch.

Embedded with powerful MagSafe magnets, the slim iPhone 15 case enables effortless wireless charging and easy attachment to MagSafe accessories.

Furthermore, the integrated NFC chips allow you to use your NFC-enabled phone to check the genuineness of the case and obtain games, wallpapers, music, and other exclusive services from PitaStudio.
