CUSN6 / CUSN8

AH264 5716 stang-2

Phosphor tinbronze.

Phosphor bronze is characterized as a very pure alloy with extremely low content of impurities. Phosphor blends well with copper making the material hardly reacting on oxygen (oxidation).

Phosphor tinbronze is an alloy with high wear resistance and good mechanical properties. There are tubes, bars and plates of different thicknesses available in phosphor tin bronze.

Areas of use
Heavy load bearings, gears and worm wheels, sliding plates, trapezoidal nuts and screws.

Shapes & forms
Solid round bar, hexagonal bar, tubes, flats & squares, plates
