Abrasion resistance of different materials.<\/h3>\n
It is difficult to compare the abrasion resistance of different materials. The choice of material is best resolved through practical tests or previous experience. Laboratory tests should be used with great discretion. <\/div>\n
The values in the table should be used only as a rough guide.<\/div>\n<\/div><\/div><\/div>
