Hardiall is an extruded and drawn, spinodal hardened copper nickel-tin (CuNiSn) bronze alloy designed for high-strength applications where toughness is required. It resists mechanical wear, galling, stress relaxation, corrosion and erosion. Copper Spinodal Alloys: Part Two :: Total Materia ArticleThe primary families of copper-based spinodal alloys that have performed in a superior manner in testing are copper-nickel-tin type spinodal alloys. These alloys consist primarily of copper containing nickel in amounts of between 2 and 20 percent by weight, and tin in an amount of between2 to 8 percent by weight. Environmentally assisted degradation of spinodal copper alloy ... Cu-based alloys usually have limited mechanical strength, rendering them inappropriate for high load applications. However, improved mechanical strength can be achieved in ternary copper-nickel-tin alloys, including Cu-15Ni-8Sn (UNS C72900), through a controlled heat treatment process that causes spinodal decomposition .
