20% H2O2 Wash Down on 6000 Series Extrusion
20% H2O2 Wash Down on 6000 Series Extrusion
(OP)
I have never dealt with a 20% hydrogen peroxide wash down environment before. I know hydrogen peroxide is acidic. Working with 6000 series aluminum extrusions, what would be a recommended finish for the extrusions? I need to clarify with the customer, there specs mention "occasional wash down", and I'm not sure if that is weekly, monthly, or other.
These extrusions will be attached to painted steel racks, do I need to isolate them to prevent further corrosion? The contact area will probably be very small, perhaps 8sq inches over a length of 9ft.
Thanks in advance.

There are also some high end nickel/teflon infused matrix coatings out now that will actually fuse with the substrate and the teflon "self heals" the surface so any defects do not spread. The best one I know of, Rossi is using for new gearboxes. It's some proprietary coating done in Italy. That's all I really know about it.
Otherwise you could probably talk with General Magnaplate and they could also recommend something.
