Technical Information

Shellcast High Strength Aluminum Castings with Superior Mechanical Properties

Controlled Solidification Process

As part of our Standard Foundry Procedure, all castings produced at Shellcast are poured utilizing controlled alloy chemistry, a robotic pouring arm and Controlled Solidification chambers, resulting in mechanical properties superior to those obtained with solidification under standard atmospheric conditions.

Rapid Solidification Process for Elevated Mechanical Properties

For requirements with elevated mechanical properties, Shellcast provides a proprietary Advanced Rapid Control Solidification Process during which computer controlled rapid solidification is achieved, ascertaining mechanical properties exceeding those obtained with our standard Controlled Solidification Process.

Alloys Cast

Aluminum based: C355, A356, A357, A201, 40E(D712) and Vanasil. In addition, custom formulations are available from our metallurgical lab.
