Instrument Manufacturing

300 Below’s cryogenic treatment process has helped a number of musical instrument manufacturers to obtain the best quality sound of music while also reducing tooling costs during the musical instruments assembly process.

How can instrument manufacturers benefit from using cryogenic treatment?

  • Treating the parts used to make instruments
  • Treating the metal structures of brass musical instruments
  • Treating the strings for wood musical instruments


Cryogenically treating metal tools and components used to shape, bend, work, form, drill, press, cut, shave, and hammer musical instruments may help to increase their functional and operational lifespan. In larger production facilities where downtime may cause production backlogs while raising expenses from assembly line downtime, 300 Below’s cryogenic process can be added to parts that are prone to frequent wear or breakage. We offer a competitive advantage that keeps manufacturers in the green by reducing tooling and maintenance expenses caused by unnecessary breakage or changeouts.


By treating an instrument at sub-zero temperatures, inherent stresses within the structure of the brass called “residual stresses” are released. This allows instruments to play and sound the way it was designed to perform. Instruments are also reported as being easier to clean.


Silver-plated bronze or copper guitar strings, and high-carbon steel piano strings, vibrate at a resonant frequency that is improved during 300 Below’s cryogenic processing operations.

The velocity of propagation of a wave in a string (v) is proportional to the square root of the force of tension of the string (T) and inversely proportional to the square root of the linear density (mu) of the string.

By subjecting metal piano strings or bronze / copper guitar strings to our deep cryogenic process, we create an improved harmonic property as a result of a structure that maintains tension more evenly while ensuring the density of the string is not disrupted by cracks, tears, overlaps and gaps in its molecular structure.

For instrument manufacturers, this richer sound and tonality is indicative of a finer high-end musical instrument like guitars, and is the type of sound sought by discriminating clients who seek the best quality and investment. 300 Below provides a significant competitive advantage to manufacturers using our process, which is why we have treated instrument parts, manufacturing components and strings for some of the biggest names in the music business.

What musical instruments can benefit from cryogenic treatment?

  • Pianos
  • Guitars
  • Cymbals
  • Saxophones
  • Trumpets
  • Trombones
  • and any other horn or metal stringed instrument

What are the benefits of the cryogenic musical instruments manufacturing?

  • Strings last longer.
  • Time between replacing strings (string replacement maintenance) is significantly reduced.
  • Instruments for making music stay in tune longer.
  • Response when playing an instrument is much better.
  • Tonality and warmth is consistent through all of the registers.
  • Both tone center and overall quality of waveforms are more consistent throughout the registers.
  • Less resistance to sustain a note means more endurance and longevity in holding a note.
  • The upper registers feel easier and more open to play.
  • Much better control in dynamics.
  • Valves become more responsive and smooth.
  • Increased tonal quality and volume.
  • Reduction in resistance as a result of a more coherent structure.
  • Enhanced molecular covalent bonding results in a more coherent audio signal while enhancing the signal to noise ratio.
