Abstract:
A method of manufacturing a light weight high performance aluminum connecting rod which does not suffer substantial elongation or deformation under high performance conditions without compromising strength characteristics, comprising:providing an extruded aluminum alloy bar stock blank, said aluminum alloy comprising 7055-T77511 aluminum alloy material capable of withstanding high compressive loading;heating said extruded aluminum alloy bar stock blank to a forging temperature having a range from approximately 500.degree. Fahrenheit to approximately 800.degree. Fahrenheit;forging said heated extruded aluminum alloy bar stock blank into a connecting rod forging; and machining said connecting rod forging into a finished connected rod having improved compressive yield strength with a relatively long operating life without compromising dimensional parameters.
