Aluminum often strongly solders to uncoated steel dies when cast in permanent metal molds. To address this problem, metalcasters use lubricants, which often need to be applied to the die prior to the production of each casting. For high-pressure diecasting, organic lubricants are sprayed onto the die, while for permanent mold casting, ceramic coatings and graphite are used. Although the application is necessary, they cause various problems, such as reducing the quality of the castings and the creation of costly housekeeping issues. In addition, they are expensive and add to the cost of the casting.
