Aluminum alloy sectional material for producing bicycle parts and preparation method thereof

The invention discloses an aluminum alloy sectional material for producing bicycle parts and a preparation method thereof. According to the aluminum alloy sectional material for producing the bicycleparts and the preparation method thereof, the problems that in the process that the aluminum alloy sectional material is used for machining production of the bicycle parts, the aluminum alloy sectional material is prone to cracking after being stamped and bent for multiple times, the produced parts are likely to have cracks, and consequently the product quality is affected are solved. According tothe key points of the technical scheme, the aluminum alloy sectional material is characterized by being prepared through the step that Si, Fe, Cu, Mn, Mg, Cr, Zn, Ni, Ti, V, Zr and Al of the specificweight ratio are smelted, refined, cast, extruded and cut. The purpose that the aluminum alloy sectional material is more suitable for machining of the bicycle parts and not prone to cracking after being stamped and bent for t
