Every note you fret rides on a thin strip of metal, yet most players never give that metal a second thought. The fret wire under your fingers shapes how the guitar feels, how it sounds, and how often it lands on a repair bench.
Two metals do nearly all the work on modern guitars, and they wear very differently. Knowing which one sits on your neck helps you predict repairs before they sneak up on you.
This guide explains what fret wire is made from, why frets wear down, and what a refret really involves. Let’s start with the metal itself.

What Are Guitar Frets Made Of?
Most guitar frets are made from a metal alloy called nickel silver, with stainless steel serving as a harder, more durable alternative. Despite the name, nickel silver contains no actual silver.
The word “fret” is sometimes used to describe the space between the metal strips rather than the strips themselves. You might hear someone refer to the first fret, second fret, and so on, pointing to those locations on the fingerboard.
This usage is common in song tutorials and is generally fine because people still understand the message.
However, guitar makers and repair technicians use a stricter definition: the fret is the metal strip itself. If you ever need work done on your hardware, use “fret” only to mean the metal strip so there’s no confusion with the technician.
Fret Wire Materials
Knowing what guitar frets are made of helps you appreciate your instrument and spot when something needs attention. Two materials dominate the market.
1. Nickel Silver
The metal used in most frets is called nickel silver, even though there’s no actual silver in the alloy. In most cases the composition is roughly 18% nickel and 80% copper, with the remainder being tiny amounts of lead, zinc, and cadmium.
Higher-quality fret makers use less copper and add more zinc to increase hardness and boost longevity. These frets cost more, but the extra money is worth it because you get fewer problems despite heavy use.
Players with a strong grip will especially appreciate this harder fret wire.
2. Stainless Steel
Stainless steel is more familiar in stair railings and commercial kitchen equipment, but it’s a versatile material that has found its way into countless applications. It’s sometimes used for frets as an alternative to the traditional nickel silver alloy because of its impressive durability.
Players who are tired of fret problems may ask a luthier to refret their guitar with custom-made stainless steel. Just be prepared to spend more, because the work commands a higher price.
Stainless steel is hard to shape and can wear down a luthier’s precious tools, so the higher rates are justified.
How Many Frets Does a Guitar Have?
Different guitar types have different numbers of frets along the neck. A classical guitar typically has 19 frets, and the neck usually joins the body around the 12th fret.
The upper frets are playable, but the hand position can get awkward.
This is why some guitars have inwardly curving shoulders known as cutaways. A cutaway makes it easier to reach the higher frets, which helps players with small hands.
Slender necks can also help in this situation.
If you’re shopping for steel-string acoustic guitars, you’ll notice the number of frets varies widely. Most have 20 frets, but some have quite a few more for extra range.
A cutaway becomes more necessary as the fret count climbs, so the highest frets are actually usable.
Electric guitars generally have between 21 and 24 frets, and the neck and body may not join until as late as the 19th fret. Cutaways are standard on this style of instrument for exactly that reason.
The Parts of a Fret
A fret is made up of distinct parts. The domed top is called the crown, and the part embedded in the fretboard is called the tang.
To keep the fret locked in place, the tang usually has a barb on both sides that grips the slot in the wood.
The crown takes all the contact from the strings, which makes it the most vulnerable section of the fret. Over time, that constant contact is what causes the wear and tear covered in the next section.
Common Fret Problems
Frets endure thousands of string presses, so problems eventually show up. The two most common issues are fret buzz and intonation trouble.
Fret Buzz
Metal strings are popular because of their durability and tone, and steel strings in particular last a long time. The downside is that rubbing a metal string against metal frets eventually causes visible wear.
You’ll start to see indentations on the fret’s crown where the strings sit.
You’ll also hear the difference, and that’s when the problem can no longer be ignored. Owners typically report a buzzing sound.
Keep in mind that many other factors can cause fret buzz, including poor manufacturing and the condition of the fretboard wood, so check carefully before blaming the fret wire alone.
Intonation Issues
Sometimes you get mixed results when playing: one chord sounds great while another sounds off. This is an intonation issue, and it often points to an underlying problem that needs correction.
Minor adjustments may be enough depending on the exact cause.
If worn frets are to blame, you may want to replace them with new ones or have the existing ones repaired. Sometimes the frets are simply too high, in which case the appropriate adjustments must be made.
If the problem lies elsewhere, more troubleshooting is needed to find the root cause.
Fret Repair and Refretting
When the crown is dented but the damage isn’t too deep, a technician can repair it. They remove a small amount of material from the crown to smooth everything uniformly.
The frets are first flattened and then given a shallower domed shape so they play cleanly again.
If there are deep pits, a refret is usually the better choice. A skilled craftsman replaces all of the frets, which is difficult, time-consuming, and expensive.
A partial refret costs less because only the most affected frets are replaced. Some players opt to replace the neck instead, though that’s only possible on bolt-on models.
Frequently Asked Questions
Do guitar frets contain real silver?
No. Nickel silver is named for its silvery color, not its contents.
The alloy is mostly copper and nickel, with small amounts of other metals like zinc, and contains no actual silver at all.
Are stainless steel frets worth the extra cost?
For many players, yes. Stainless steel frets resist wear far longer than nickel silver, so you refret less often and deal with less buzz over the life of the guitar.
The trade-off is a higher installation cost because the metal is harder to work and tougher on a luthier’s tools.
How long do guitar frets last?
Anywhere from several years to decades, depending on how hard you play, your string material, and the fret metal itself. Nickel silver frets on a regularly played guitar may show noticeable wear after several years, while harder stainless steel frets can last much longer.
Players with a strong grip and heavy strings tend to wear frets down faster.
Can worn frets be repaired without a full refret?
Often, yes. If the dents in the crown are shallow, a technician can level and recrown the frets to restore a smooth playing surface.
A full refret is reserved for frets with deep pits or wear that leveling can’t fix, and a partial refret can replace just the worst frets to save money.
Final Thoughts
Most guitar frets are made from nickel silver, a copper-based alloy that balances workability and tone, while stainless steel offers greater durability for players who want frets that last. Neither contains real silver, despite the name.
Understanding the parts of a fret and the materials they’re made from helps you recognize wear early and decide whether a simple level-and-crown or a full refret is the right fix. When in doubt, a qualified luthier can assess the crowns and recommend the most cost-effective repair.
Take care of your frets and your guitar will play in tune and feel comfortable for years to come.
