Thread: What temp does aluminium melt ?

Shivers , speaking of Ice-Cream , I bought me some icecream from woolies and left it inside the Glovebox of the disco

How rude!!!!!!
Ice cream left out in the Disco like that
Just stepped outside and nearly melted away myself, it's been a long, long, time since I've felt heat like this.
I take my hat off to all those wonderful firefighter's out there fighting those fires.
If I could I'd buy them all a beer after today.

660.25 Degrees celsius according to wikipedia. I'm not sure whether Brimabright Magnesium / Aluminium alloy has a higher or lower melting temp than that, but I do know that you should avoid exocet missiles (for those old enough to remember the Falklands and the Brimabright ship).

weather radar shows some rain, but a glance out the window shows that it's actually a dust storm.

The doppler wind radar is out of action currently.

I've now removed the BOM Image, as the link kept updating and so became irrelevant.

it is only 41C here, 31C inside (house is well insulated) - Dubbo is actually only 39C. But step outside and it is pretty warm, none the less.

34 inside and outside in Orange.

Hope the poor thing does not melt away
Ourselves we are locked up inside and trying to keep cool, not bad at this point keeping the house dark and have the fans on and have both extractors in the bathrooms going.
And I thought it was going to be NSW that was going to be the hottest in the world today not us here in hoppers, west suburb of Melbourne.
All I know is none of us have been outside as yet, not game to open the door as there is a wind gust of 76 klm/hour.
Ice cream all round later on I think.

Better start going to Church or it'll be hotter when you die

On our back verandah it's currently 41 and the hot winds are making it very uncomfortable outside. Air con is working overtime trying to keep the house cool. There's a distinct smell of smoke around, from the fires around the Central Coast, I think.

Erich is out in the shed removing a gearbox I'm sure he's rather be doing something else in this heat.

Hope our wonderful fire fighters keep safe.

Yup the world wide web says 660 odd Deg C to melt pure aluminium....and then whatever is mixed in for an alloy may alter that.

I melted out a small ally billy on the electric cooktop when I was a kid, so that must have been a seriously poor quality version.

The Falklands warship that 'melted' was the Type 21 frigate HMS Ardent, which was hit with multiple 500lb bombs dropped by A4 Skyhawks. She lost 22crewmen in the action. She had a steel hull but ally superstructure in order to reduce weight, especially top weight. The fires generated by the bomb attacks were hot enough to distort and melt the metalwork.

Having been in the RN from 1989 onwards, there were many first hand stories and subsequent improvements to dealing with battle damage and fire fighting. The growth of warship design through the missile age had increased the use of plastics and rubber for electric and sound insulation, and better facilities for the crew had brought greater use of foam and plastics for bunks, recreation areas etc. All this stuff burns very rapidly and can be difficult to contain. Plus they also produce highly poisonous gases which knocks out your fire teams unless they have breathing apparatus available.
