FRETS PRODUCTION
SINTOMS Ltd. is a leader in produce and supply of quality frets
in Central and Eastern Europe.
 |
Those manufacturers of
musical instruments that use SINTOMS frets get 1.5 to 2
times |
reduction of costs required for fret mounting.
|
|
Due to special technologies
and materials the frets do not absorb but sustain and
support |
sounding of musical instruments.
|
|
SINTOMS Ltd. produces more
than 100 models of frets for various musical
instruments, |
of standard sizes, as well as custom-made as under the request
of a specific customer.
|
|
Frets are made from quality
materials provided by world-known producers. Main
materials |
used are as follows:
- nickel silver with 12% nickel content
- nickel silver with 18% nickel content
- stainless steel
- alloy brass
- nonallergenic alloy
- bronze with the tin content of 15%
|
|
Nickel silver frets are produced of two hardness types: standard hardness frets (of
nickel |
silver with 12% nickel content); extrahard frets (of nickel
silver with 18% nickel content).
Extrahard frets (e.h.) of over 170 НВ hardness can bear a
long-time (up to 2 years)
intensive play of a musical instrument.
|
|
Nickel silver frets are
produced with different crown forms. The most
wide-spread |
are arc-shaped (conventional) and triangular crown forms.
Triangular frets allow to
play an instrument without “rustling” which is of special
importance while recording in
sound studios using high-sensitivity devices.
|
|
Nickel silver repair frets
have a thicker tang and are successfully used by repair
|
workshops for re-fretting.
|
|
Frets of stainless steel are
of increased wear-resisting property (w.p.), they have
up |
to 40 HRC hardness. These are practically “ageless” frets.
|
|
Frets of alloy brass are
goldish color and of standard hardness.
|
|
|
Frets of nonallergenic alloy
are silver-coloured, of standard hardness, intended for
musical |
instruments made of materials causing no allergic reactions in
players.
|
|
Bronze frets with 15%
content of tin (the most ringing bronze). The color of
frets |
is gold, their hardness is similar to the hardness of extra hard
nickel silver frets. These
unique frets especially show themselves on high-quality electric
guitars.

Frets are of high
manufacturing accuracy (±0.02
mm); the crown surface
finish is at least |
of class 8; the tang is smooth, with studs in the form of
triangular pyramids or without
studs; the shoulders are straight.
|
|
The frets with studs fit
perfectly the surface of the fingerboard, they hold fast
in the |
kerf slot, and can be easily replaced without breaking the
fingerboard surface.
