Dot, I know it isn't clever to answer a question with a question, but what is young Gman trying to achieve? If you give us a clue maybe we can help.

Stainless steel slides well in aluminum, but does wear it out over time. Have seen some use lubricant to make it slide better, but that only binds with the shavings of aluminum and clogs it up. Depending in weight, a piece of hard synthetic carpet attached will make it slide much better.

metal to metal doesn't play well with aluminium.
Solid HDPE would work, what are you rubbing on it?
HDPE is the type of plastic chopping boards are made of
I have some 6mm UHDPE I could send you, typically used on top of truck turntables

Want to make our table in the bus slide along against the wall using 2 aluminium channels, however the max size of the metal that slides in the channel is 5mm x 25mm. Have put sliding door rollers in the aluminium channel and have also sprayed lube in the channel but still it is hard to move because the rollers are grinding off the aluminium as it moves and clogs up. Hope I have got this right

Would help if we knew how much room you have to play with eg between the door and the runner.
What about a bit of an old plastic cutting board cut to size.
If they both have a channel you could use a few ball bearings they run fairly easy. Just need a dob of something to stop them running out.
If tight clearance try some door grease from Repco or similar.

What about S/S channel rather than alloy?

Thanks guys, G is going to try using polished steel with assistance from a lubricant.
Brian um what door are you speaking of? the table is on the opposite wall to the door.. have you been sipping that special honey drink??

I'd still consider the sliding door hardware.

Mount the carriage wheel assembly on the end of the table and run it in the rail.
