Wear resistance in various materials

These are difficult to compare and any material is best chosen based on test results and/or previous experience and
usage. The results of lab tests should only be used with discernment.
The figures in the table below should only be considered as giving a rough indication.

Relative wear resistance
Polystyrene	approx. 30
Amide resin 66	approx. 6
HD-polythene	approx. 19
Polytetrafluorethene	approx. 5
Epoxy resin	approx. 16
Polyurethane	approx. 0,5-0,8
Rubber	approx. 0,6-1,9
Aluminium	approx. 5
Steel (high tensile)	approx. 0,5-0,7
Forge iron	approx. 1

Lower figures indicate higher wear resistance.
Test conditions: wear particle size approx. 1.1 mm, speed: 3.55 m/s.
