Tungsten carbide ranks 8.0-9.0 on the Mohs scale, second only to diamond among ring materials. Maximum scratch resistance, dense heft on the finger, and shatter-resistant only under extreme impact. Cannot be resized; Aydins offers a Sizing Exchange program instead.
If you are shopping for a durable wedding band, you have likely asked: how hard is tungsten? This is a critical question for any man who wants a ring that withstands daily wear. Tungsten carbide is known for its extreme hardness and scratch resistance. At Aydins Jewelry, we craft rings for men who value strength and longevity. Here is the complete guide to tungsten hardness on the Mohs scale.
What Is the Tungsten Hardness Scale?
Tungsten is one of the hardest metals used in jewelry. On the Mohs hardness scale, which ranks minerals from 1 (talc) to 10 (diamond), pure tungsten ranks between 7.5 and 8. However, the tungsten used in wedding bands is tungsten carbide. Tungsten carbide is a compound of tungsten and carbon. Its Mohs hardness is between 8.5 and 9. This makes it significantly harder than most other metals.
To put this in perspective, a standard steel wedding band ranks around 4.5 to 5 on the Mohs scale. Titanium is around 6. Cobalt chrome is about 7. Tungsten carbide at 8.5 to 9 is nearly as hard as sapphire or ruby. Only diamond, with a perfect 10, is harder. This extreme hardness is why tungsten carbide rings are marketed as scratch resistant. They resist everyday abrasions from keys, tools, and surfaces.
Tungsten Hardness vs Steel
A common question from buyers is tungsten hardness vs steel. Steel is a durable metal, but it is much softer than tungsten carbide. Steel wedding bands will scratch and scuff over time. They can also bend out of round with enough force. Tungsten carbide rings, by contrast, will not bend. They are rigid and maintain their shape. However, this rigidity means they can crack or shatter under extreme impact. Steel rings can be resized. Tungsten carbide rings cannot. This is why Aydins offers a Lifetime Sizing Exchange program instead of traditional resizing.
Diamond vs Tungsten Hardness
Another frequent search is diamond vs tungsten hardness. Diamond is the hardest natural material on Earth. It scores a perfect 10 on the Mohs scale. Tungsten carbide scores 8.5 to 9. Diamond is significantly harder. However, diamond is not commonly used for the entire band of a wedding ring. Diamond is used as a gemstone. Tungsten carbide is used for the band itself. For practical daily wear, tungsten carbide offers excellent scratch resistance without the cost and fragility of a diamond band.
How Hard Is Tungsten Carbide Compared to Other Ring Materials?
Here is a quick comparison of common ring materials on the Mohs hardness scale:
- Diamond: 10
- Tungsten carbide: 8.5 to 9
- Sapphire: 9
- Cobalt chrome: 7 to 8
- Titanium: 6
- Stainless steel: 5 to 6
- Gold (14K): 2.5 to 3
- Silver: 2.5 to 3
Tungsten carbide is harder than every common jewelry metal except diamond. This is why it is the top choice for men who work with their hands or want a ring that looks new for years.
How to Choose the Right Tungsten Ring
When selecting a tungsten ring, consider these factors:
1. Grade of tungsten carbide. Look for jewelry grade tungsten carbide. Lower grades may contain nickel binders that can cause skin reactions. Aydins uses hypoallergenic cobalt free tungsten carbide.
2. Comfort fit. A comfort fit band has a domed interior. This makes the ring easier to slide on and off. It also feels more comfortable for all day wear.
3. Width and thickness. Wider bands are more durable. Thinner bands may be more comfortable but can be less impact resistant.
4. Finish. Tungsten rings come in brushed, polished, matte, and black finishes. Brushed finishes hide scratches better than high polish.
5. Engraving. Tungsten is hard to engrave. Aydins uses laser engraving for precise, permanent inscriptions inside the band.
Materials and Construction of Aydins Tungsten Rings
All Aydins tungsten wedding bands are made from high quality tungsten carbide. We use a cobalt free binder to ensure the rings are hypoallergenic. Each ring is finished in our Texas workshop and then polished to a high luster. The comfort fit interior is standard on all our bands. We also offer inlaid options with materials like wood, carbon fiber, and ceramic. These inlays are set into the tungsten carbide for a unique look without compromising durability.
Sizing, Comfort Fit, and Engraving
Getting the right size is essential for a tungsten ring. Because tungsten cannot be resized, we recommend using our free ring sizer. Measure your finger at the end of the day when your hands are warm. If your size changes, use the Aydins Lifetime Sizing Exchange. You can exchange your ring for a different size at no cost.
All Aydins tungsten rings include Free Engraving. We laser engrave the inside of the band with your message. Common engravings include names, dates, and short phrases. The engraving is permanent and will not wear off.

Frequently Asked Questions
Do tungsten rings scratch?
Tungsten carbide rings are highly scratch resistant. They rank 8.5 to 9 on the Mohs hardness scale. They will resist scratches from most everyday objects. However, they can be scratched by harder materials like diamond or sapphire.
Are tungsten rings hypoallergenic?
Yes, when made with a cobalt free binder. Aydins uses cobalt free tungsten carbide. This makes our rings safe for people with metal allergies.
Can tungsten rings be resized?
No, tungsten carbide rings cannot be resized. The material is too hard to stretch or compress. Instead, Aydins offers a Lifetime Sizing Exchange. You can exchange your ring for a different size.
What if my tungsten ring breaks?
Tungsten rings are durable but brittle. They can crack or shatter under extreme impact. If your ring breaks, contact Aydins. We will replace it under the Aydins Lifetime Warranty.
How fast does Aydins ship?
We offer Free FedEx 2-Day Shipping on all orders. Most rings ship within 1 business day.
What is the difference between comfort fit and standard fit?
Comfort fit has a rounded interior. This makes the ring easier to put on and remove. It also feels more comfortable. Standard fit has a flat interior. It can be harder to slide on and may feel tighter.
How do I measure my ring size?
Use our free ring sizer. You can also measure a ring you already own. Follow the guide on our website. Measure at the end of the day when your fingers are largest.
