Lead is a versatile metal with several properties that make it suitable for sand casting. It is highly malleable, allowing it to easily fill complex mold cavities and produce detailed components. Its density provides excellent weight to parts, making it essential for applications where balance and mass are critical, such as in fishing lures and counterweights.

The Aluminum Casting Process

Clay, typically bentonite, acts as a binder in the green sand mixture, giving it the ability to retain its shape when molded. Bentonite is favored because of its swelling properties when combined with water, which enhances the binding effect and allows for better mold strength during the casting process. Water in the mixture also plays a crucial role by activating the clay, creating the plasticity needed for the molding process. Proper moisture content is essential; too much water can lead to defects in castings while too little can make the sand too dry to form adequate molds.
