- How can I reduce Fe content without high tech machinery?
- How much can I expect to pay for a 1000lbs sow mould? Is there a place that sells them used?

If your metallurgist is not already adding iron to your melt picking up stray iron, have your smelter manager check the furnace refractory and holding cells along with runners for cracks that may allow the molten aluminium to come into contact with iron.



Aluminium in its molten state becomes a solvent.

Metallurgy of aluminum is way beyond my scope of education, if your smelter metallurgist is unable to adjust the chemistry to suit the new contract I would strongly suggest you hire another who has the ability to do so..
