The ally isn't softer at 160 degress C than it is at 0 degrees C

Its properties certainly can change at 160C. I would say its more likely to fracture but not because its soft, more probably because its become grainy.
Google "preciptation heat treatment".

I would imagine the aluminium alloy is resistant to this precipitation heat treatment to a major degree, not daft these nips. The coefficient of thermal expansion was really the important on here but Mr KAFA seems to think the alloy gets soft at operating temperatures. If he also knew about copper grease he would know, although thermally resistant to a point, it is a major no no once the evaporables evaporate and it becomes a congealed mass. You can look that up on the internet too.


All you need to do to look clever is pretend to know more than the masses and in this case it appears to have worked.


I'm newbieish on here but well known in other places, some say regrettably, and one of my saying has, for years, been bad advice is worse than no advice. Poor old gnashipoos cannot have any substatiation to a lot of his arguments as there is nothing to substantiate them as they are wrong, some of them anyways, some have a modicum of actual information and truth though.
