Thomastik-Infeld Thomastik Power Brights PB110
Lower PFAS concern, steel string instruments lack typical Teflon-family coating coatings.
Thomastik Power Brights are premium phosphor bronze and steel violin/string instrument strings with no disclosed PFAS treatment. String instruments are not typically treated with PFAS-containing coatings, though Thomastik provides no explicit PFAS statement. No public lab testing or recalls reported.

The full breakdown
What it's made of and why it matters
Thomastik Power Brights PB110 are constructed with a steel core wrapped in nickel-plated steel wound strings, a standard construction for electric guitar strings. The nickel plating serves both acoustic and durability purposes, providing brightness and extending string life. No Teflon-family coating coatings, ceramic glazes, or synthetic polymer matrices are involved, eliminating classes of hazards common to coated cookware or plastic food storage.
The brand's record and disclosure
Thomastik-Infeld is an Austrian string manufacturer established in 1919 with no public record of safety recalls, hazardous material disclosures, or regulatory violations related to this product line. The brand does not publish detailed material safety data sheets or certifications specific to heavy metal content or nickel leaching, which is typical for the musical instrument industry but leaves independent verification limited. No established controversy or litigation involving this product exists in public record.
How it compares in its category
Power Brights occupy the mid-to-premium tier for electric guitar strings; competing brands (D'Addario, Ernie Ball, GHS) use similar nickel-wound or pure nickel constructions with equivalent safety profiles. Thomastik's Austrian manufacturing and reputation for longevity place it slightly above budget-tier strings, which may reduce replacement frequency and cumulative exposure. No material advantage or disadvantage versus peers in terms of documented safety hazards.
If you buy it
Store strings in a dry environment to prevent rust and nickel migration; exposure to sweat and moisture over months is normal and poses minimal risk. Replace strings when they lose brightness, develop rust spots, or break, typically every 1-3 months depending on play frequency. Dispose of spent strings in regular waste or bring to a recycling center that accepts scrap metal; do not incinerate. Wash hands after extended playing to remove nickel residue, particularly important for individuals with nickel contact allergy.
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.”
Nickel contact allergen
Nickel-plated steel strings can release nickel ions through skin contact with moisture and sweat, particularly during extended play. Individuals with documented nickel allergy may experience dermatitis on fingertips or hands; this is a known issue in the guitar string category but not specific to Thomastik brand.
Heavy metal leaching in core material
No public testing or recall exists documenting cadmium, lead, or other heavy metals in Thomastik-Infeld steel core strings. Steel string cores typically contain iron, carbon, and trace elements; leaching into saliva during oral contact (mouthpiece play) has not been reported as a concern.
Coating degradation and particle release
Nickel plating may wear or chip over extended use, exposing underlying steel and potentially shedding microscopic nickel particles. This is cosmetic and mechanical wear rather than a manufacturing hazard; no evidence suggests this causes systemic exposure or health effects from normal guitar playing.
Contamination from manufacturing residue
Thomastik strings are manufactured under standard industrial controls. No documented recalls or testing reveals contamination with lubricants, oils, or chemical residues; strings are typically wiped clean before packaging.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
