Almost all??? Brass and even copper are also used in heater blocksQuote

Almost all hot ends are aluminum block with a steel threaded tube for filament.......
A brief perusal of ebay and my old cartridge cases shows no aluminium - only stainless steel.Quote
Cartridge case is commonly aluminum....
Irrelevant. Does it do the job is the only questionQuote
soft copper powder providing anti-seize agent --- NOT thermal tranfer.
And definitely not intended for use at hotend temperaturesQuote
Look at cpu thermal paste --- usually a silver oxide or silver paste specifically formulated for heat transfer.

Extract from the link above:
"Specifications:
Extended Temperature Limits:
Peak: –50°C to >180°C
Long-Term: –50°C to 130°C"
Looks just the job for a heater cartridge where filaments need to be heated to between about 190 and 280 deg C.

How do you get from a limit of 130°C to using it at 280°C ?
