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.

маркированный список

Frets of nonallergenic alloy are silver-coloured, of standard hardness, intended for musical

            instruments made of materials causing no allergic reactions in players.

маркированный список

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.
