Ampco Metal AMPCO® 45 Nickel-Aluminum Bronze, Extruded and Drawn Rods, ≤ 25.4 mm.
Categories:	Metal; Nonferrous Metal; Copper Alloy; Bronze
Material Notes:	AMPCO 45 is a high strength alloy with mechanical properties beyond the range of commercial nickel-aluminum bronzes. This is due to its special manufacturing process. Applications: AMPCO 45 is recommended for heavy-duty high-loaded mechanical and corrosive applications. Typical applications involving abrasive wear, friction, deformation, chemical erosion include: aircraft bearings / bushings; pump and marine shafts and wear rings; valve spindles and seats; machine tool parts. The spark-resistance properties make it suitable for safety tools and machine tool components in explosive environments.
Key Words:	AMS 4640; ASTM B.150
