Titanium posts for the anodising industry
Those marvellous folk at Moss Metal Finishing have ordered some more posts. They use these to secure the parts for anodising onto the framework thats lowers into the tanks of goo. They have to be titanium otherwise they would disolve during the anodising process. Normally they should be made from grade 1 or 2 titanium, i.e. commercially pure, because grade 5 contains 4% alluminium which in theory will be leached out during the process and cause them to shrink. But the grade 1 ones they used to use (made by someone else i hasten to add!) broke quite regularly, so we now use grade 5. and by all accounts they haven’t shrunk and haven’t broken despite heavy useage.
They all have an M8 tapping to a depth of 20mm in the fat end
and they all have 2 flats at 13mm A/F
