ToughMet® 3TS Rod TS120U (C72900) – Ultra‑Strong, Ultra‑Tough Alloy for Extreme Loads

ToughMet 3 TS alloy is a cold worked, spinodally hardened alloy designed to provide high strength for the most demanding static structural loads and pressures. It provides high toughness combined with high strength to resist dynamic impact loading. ToughMet 3 TS alloy provides galling resistance, high bearing performance and compatibility with many sour environments or salt water. It is non-magnetic and very easy to machine into complex components.
