Toughmet Nickel Bronze Best Today

Spinodal hardening is achieved via: Solution anneal → Cold work → Aging at 300–400°C → Nanoscale Cu-Ni-Sn modulated structure.

Unlike traditional alloys that rely on precipitation hardening, ToughMet undergoes . During heat treatment, the copper, nickel, and tin separate into two distinct phases—a hard nickel-tin phase embedded within a softer copper-nickel matrix—without a change in crystal structure. This microscopic structure provides:
