This is a utility to estimate the dimensions of a feature after sulphuric anodising or hard anodising. It is generally not necessary to calculate the effect of chromic anodising because growth is less than 3µm per surface - which isn't usually significant. Please note that this is an estimate only and relies on this tool being used correctly. Contact us and we can verify calculations.
Warning: This calculator assumes a 50:50 ingress/growth ratio. For 2000 and 7000 series aluminium in particular, this may vary up to 70:30. This is likely to be a significant consideration at higher thicknesses, such as with hard anodising.
