ToughMet® is Brush Wellman’s
solution to your severe service material problems. By applying our EquaCast®
process, tailored alloying additions and spinodal hardening technology,
we have engineered ToughMet® to provide attributes beyond those typically
found in a high-strength copper alloy.
- Exceptional resistance
to corrosion and cavitation
- Outstanding lubricity
and durability in demanding applications
- Highly uniform composition
in all product forms
- Available in a wide range
of continuous-cast shapes and sizes
ToughMet® 3 in
the cast and spinodally hardened (CX) condition exhibits tensile strength
up to 120 ksi and hardness up to HRc 34 in a Copper - 15% Nickel - 8% Tin
alloy with excellent machinability.
