Titanium Grade 1, UNS R50250

COMMERCIALLY PURE TITANIUM: GRADE 1

Available forms: Strip, Coil, Foil, Wire, ASTM B265 GR1, ASTM F67

Applications: Bellows, aircraft structural, honeycomb, gaskets, aircraft skin, heat exchanger parts, deep drawing applications.

Description: Commercially Pure Titanium Grade 1 is one of the softest and most ductile grades exhibiting the greatest formability. It has excellent corrosion resistance property, excellent weldability and is used in a wide variety of applications. This grade material is mainly used in marine and chemical industries where the parts are subjected to very harsh environments. This material is also used for fabricating anodes for cathodic protection applications.
