AMPCO® 8 Extruded & Drawn Rods – High Strength Aluminum Bronze for Superior Performance
AMPCO® 8 extruded has a high tensile strength and a good yield along with an inherent toughness and ductility not usually found in a single alpha phase aluminium bronze. During the extrusion process the metal is hot worked resulting in a compact grain structure free of inclusions or other defects and improved physical properties.
