2. Brochure - Alloy 25 For The Oil And Gas Market

   Alloy 25 is the material of choice for downhole drilling tools, production and completion tools, subsea and wellhead products. The alloy is also used for highly demanding applications like MWD/LWD tools, drill collars and subs, flex subs and shafts, drill rods, drill bit bushings, valve components, pump shafts and fasteners.

3. Data Sheet - Alloys 25 and 165 Forgings and Extrusions

   Alloy 25 provides the highest strength of any copper alloy, with electrical and thermal conductivity considerably greater than other high strength copper alloys. Alloy 165 provides strength close to that of Alloy 25, with slightly lower beryllium content. These alloys feature high fatigue strength and resistance to wear, corrosion, galling, and stress relaxation. Typical applications for parts finished by forging or extrusion of these alloys include undersea instrument and repeater housings, generator rings and resistance welding components.
