Default noise from radiators when heating is coming on/off

the expansion of the radiator causes movement.


That is what is causing the noise. Expansion against a "sticky"
surface tension builds up enough to overcome the stickion and "click"
or on the case of one of ours "doing" quite loud... Track down the
sticky contact point and lubricate it, not sure what with oils will
evaporate, grease will melt. Graphite powder?
