ABSTRACT:
Methods for making an aluminum alloy bicycle frame and for making tubes for such frames including use of an aluminum alloy containing about 0.5 to 1.3% magnesium, about 0.4 to 1.2% silicon, and about 0.6 to 1.2% copper and preferred practices for making extruded and drawn tubing of the alloy and making bicycle frames from the tubing. The preferred practices include extrusion temperature control and other aspects of extrusion and drawing.
