Fender Super Nickel-Plated Steel Electric Guitar Strings
Lower PFAS concern, traditional guitar string materials have no typical PFAS application.
Fender Super Nickel-Plated Steel strings use conventional materials (steel core, nickel plating, phosphor-bronze wrap) with no known PFAS-prone manufacturing steps. Guitar strings are not subject to waterproofing, grease resistance, or nonstick treatments that typically introduce PFAS.

The full breakdown
What it's made of and why it matters
Fender Super Nickel strings use a steel core wound with phosphor bronze wrap, then electroplated with nickel. The nickel plating serves as a corrosion barrier and tonal conductor, while phosphor bronze adds warmth and sustain. This is a conventional guitar string construction used across the industry for decades. None of these materials are known to leach into skin or saliva during normal playing.
The brand's record and disclosure
Fender has published no formal material safety data sheets or heavy metal testing for guitar strings, which is typical for the category. The company has no documented recalls or safety controversies specific to Super Nickel strings. Fender's parent company (Yamaha as of 2023) maintains general environmental compliance but does not voluntarily disclose string-specific testing results. Standard industry practice does not require third-party certification for guitar strings.
How it compares in its category
Nickel-plated steel is the most common electric guitar string core material; phosphor bronze winding is standard midrange wrapping. Alternatives include pure nickel (warmer, more prone to corrosion) and stainless steel (brighter, more durable). Fender Super Nickel occupies the mainstream position: affordable, durable, and carrying no reported safety disadvantages versus competitors like D'Addario or Ernie Ball in the same tier.
If you buy it
Wash hands after playing to remove zinc and copper residue from sweat interaction with the windings; this is good practice for any metal strings. Store in a dry environment to prevent corrosion that could pit the plating. Replace strings every 3 to 6 months depending on use; worn strings lose tone and can snap unexpectedly. Nickel plating can wear off over time, exposing steel underneath, but this is cosmetic and does not affect safety.
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 dermatitis
Prolonged skin contact with nickel-plated surfaces can trigger allergic reactions in nickel-sensitive individuals (5-10% of population). Guitar string use involves repeated fingertip and palm contact; risk is low but real for sensitive players.
Zinc and copper residue from corrosion
As phosphor bronze and nickel plating degrade, microscopic metal particles accumulate on hands and can transfer to mouth and food. Acute toxicity is negligible, but chronic low-level ingestion is theoretically possible in very heavy players.
Plating degradation and steel core exposure
Standard wear mode for nickel-plated strings; exposed steel underneath is not a health hazard but indicates end-of-life. Does not release heavy metals into the user.
Heavy metal content in phosphor bronze winding
Phosphor bronze (copper, tin, phosphorus) has no established toxicity from skin contact or incidental ingestion in guitar string quantities. No test data exists for this specific product, but the material class carries no red flag.
Manufacturing process chemicals on new strings
Drawing oils and plating bath residues may remain on new strings but dissipate with hand contact and are not volatile. Fender does not disclose cleaning or passivation protocols; standard industry practice involves minimal chemical residue.
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.
