Chapter 15, Problem 1P
Attractive properties for casting alloys include low melting points, high fluidity (or runniness), and high as-solidified strength. Wrought alloys (those fabricated as solids by processes such as rolling, forging, and extrusion) are best if they possess low yield strength, high ductility, and good strain-hardening characteristics. Reflecting these differences, the Aluminum Association uses distinctly different designation systems-a four-digit number for wrought alloys and a three-digit number for cast. Aluminum casting alloys are often further classified as “recommended for sand casting,” “recommended for permanent mold casting,” and “recommended for die casting.” might different material properties be required for casting into the three different mold materials-sand, cast iron, and water-cooled tool steel? M/hat features or characteristics would be desired for each?
