The trebles are made of a high technological material, very different from nylon : different elasticity, higher density, further longevity thanks to the very specific cristallinity grade.
In fact we have been working on the following topics to guarantee the technological and acoustic qualities of this material to make it convenient for music strings :
Mastery of the elasticity and elongation,
Control of the geometrical regularity of the diameter for a perfect intonation.
Characteristics - Technology:
The KF ALLIANCE fibre has the same density and elongation properties as gut.
Its density is higher than the polyamide fibres.
The KF ALLIANCE strings are thinner than the nylon ones. They can resist a 35kg tension (harp).
The low internal frictions between the molecules increase the durability of the string beside a sustained sound.
Acoustics properties: Bright tone and clean sound, Richness of sound, Very extensive possibilities,
Incomparable power and projection of the sound, An even greater sustained sound, Very clear sound on the high and very high positions.
