Savarez Corum Alliance Classical Guitar Strings
Lower concern, classical guitar strings lack typical PFAS-use cases; no red flags detected.
Savarez Corum Alliance strings use conventional bronze winding and nylon wrapping on steel cores, materials not associated with PFAS applications. The brand makes no PFAS claims or disclosures. No public lab data or recalls exist; standard guitar string construction poses minimal PFAS risk.

The full breakdown
What it's made of and why it matters
Savarez Corum Alliance strings use a nylon monofilament core wrapped with bronze or silver-plated bronze windings. This construction is chemically stable during normal play because nylon does not off-gas volatile compounds at room temperature or under typical string tension, and bronze is a stable alloy. Unlike coated strings (which may use polyurethane or synthetic polymer finishes prone to degradation) or strings with adhesive-bonded windings, this traditional wound design avoids adhesive resins and degradation products.
The brand's record and disclosure
Savarez is a legacy French string manufacturer with no documented safety recalls or chemical disclosure controversies. The company does not publish detailed material certifications or third-party test reports for heavy metals or trace contaminants in windings. Brand transparency on supply chain and alloy purity is limited to marketing claims, but this is typical for premium string manufacturers and does not indicate a compliance gap.
How it compares in its category
Corum Alliance sits in the mid-to-premium tier of classical strings. It uses traditional nylon-and-bronze construction similar to D'Addario Ej45, Ernie Ball, and other established brands. Unlike budget synthetic-core alternatives or heavily coated strings marketed for durability, this design minimizes reliance on polymer coatings or reactive adhesives that could degrade and release compounds. Wound-string composition varies widely by maker; Savarez's bronze choice is standard and presents no known compositional advantage or deficit versus competitors.
If you buy it
Store strings in a cool, dry place away from direct sunlight to slow oxidation of the bronze windings (which is cosmetic and affects tone longevity, not safety). Do not expose to temperatures above 60°C (uncommon for a stringed instrument in normal use). Replace when you notice loss of brightness, intonation instability, or visible corrosion of windings. Wash hands after extended play if you have sensitive skin, as bronze residue can accumulate on fingers, though allergic reactions are rare.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Heavy metals in bronze windings
Bronze is primarily copper and tin, both non-toxic in wound-string form. No documented case of lead, cadmium, or other contaminants in Savarez or competitor classical strings; windings remain on the string surface and do not leach into food or drinking systems.
Nylon core degradation and off-gassing
Nylon monofilament is stable at room temperature and under string tension; no volatile organic compounds are released during normal play or storage. Degradation occurs only at sustained temperatures above 80°C, which is not encountered in typical instrument use.
Adhesive residues in wound joints
Some wound strings use small amounts of adhesive to bond core to windings at the bridge end. Savarez does not disclose adhesive type; exposure is minimal (small volume, no heating), but composition is not independently verified. This is a minor, industry-wide practice with no established safety hazard.
Contact dermatitis or skin sensitization
Bronze dust and corrosion patina can accumulate on strings and transfer to hands during play. Individuals with nickel allergy or sensitive skin may experience mild irritation; classical players with long sessions are at marginally higher risk than others. This is non-toxic but can be uncomfortable.
Microcontaminants in alloy composition
Alloy purity and trace element limits are not published by Savarez. Standard bronze alloys used in music strings typically contain only copper, tin, and negligible trace metals; no independent analysis of this product is on record, but compositional issues are extremely rare in this market segment.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
