I am doing experiments with liquid aluminium around its melting temperature in a special copper container with 5mm thick walls.
Heating by inconnel immersion heaters.
A while after aluminium melted, copper walls broke down and aluminium poured out.
Could not see this when it happened because apparatus was encased in insulation. After cooling the copper container appeared to have been eaten away in one side rather than melted. No evidence of pooled copper.
Temperature should not have gone above 670c.
What could have happend since melting point of copper is over 1000C well above experimental temperature?
Thanks
