Materion ToughMet® 3 AT90 (OD<4")
Categories:	Metal; Nonferrous Metal; Copper Alloy
Material Notes:	ToughMet® is Brush Wellman's solution for severe service material problems. By applying their EquaCast® process, tailored alloying additions and spinodal hardening technology, they 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 Uniform microstructure in a variety of wrought shapes and sizes ToughMet® 3 in the wrought and spinodally hardened (AT) condition exhibits tensile strength up to 140 ksi and hardness up to HRc 34 in a Copper-15% Nickel-8% Tin alloy with excellent machinability. Information supplied by Brush Wellman Engineered Materials. Brush Engineered Materials Inc. changed its name to Materion Corporation in March 2011.
