Coefficient of friction betwixt Steel on Steel, Steel On Aluminum, Steel On Cast Iron, Cast Iron On Cast Iron tin rank notice live flora on the next table. The connected surfaces depends on the cloth of the connected parts, roughness, surface handling as well as degreasing of the connected surfaces. And besides the next tabular array shows the coefficient of friction for dissimilar surface finishes combinations. These information volition live highly useful acre designing sliding mechanisms, bolted connexion blueprint where shear charge is applied, etc.
| Surface treatment | Material of the clamped parts | |||
| Steel on steel | Steel on cast iron | Cast atomic break 26 on cast iron | Aluminum alloys | |
| Machined degreased surfaces | 0.12 ... 0.18 | 0.15 ... 0.25 | 0.18 ... 0.25 | 0.08 ... 0.15 |
| Areas without surface treatment | 0.15 ... 0.25 | 0.18 ... 0.30 | 0.20 ... 0.30 | 0.12 ... 0.20 |
| Scorched surfaces | 0.35 ... 0.55 | - | ||
| Sand blasted surfaces | 0.45 ... 0.55 | - | ||

Note that these frictional coefficients are for non plastic welded connections where huge bonding forcefulness are applied. Thus for plastic welded connections frictional coefficients volition live much higher. (almost 0.9)
