Ullrich Aluminium: Useful Formulae

To calculate Nominal mass (kg/m) of extruded aluminium sections, tube, etc: download pdf file of linear conversion tables

  • (a) Calculate cross-section area (mm2)
  • (b) Multiply by 0.00271

To calculate Factor (i. e. the "difficulty of extrusion" factor)

  • (a) Calculate the perimeter of the section (Note: for hollows, add outside perimeter and inside perimeter)
  • (b) Divide this by the nominal kg/m of the section
