Molten Aluminum Brass can be poured into either an empty Casting Table to make a Blank Cast, or a Casting Basin to make a Block of Aluminum Brass. The molten metal is also used to make part casts by pouring the metal over an individual tool part. It is a cheaper cast material than gold.
Aluminum Brass has no uses other than making Casts, Drawbridges, and Igniters from Tinker's Mechworks. It cannot be made into tool parts.
