The tensile strength of the material is the amount of stress that it can take before complete failure, and the yield strength is the amount of stress before the material is permanently deformed (try jumping on an old frame until you bend it and you have exceeded the yield strength of the material). Percent elongation is the amount of deformation that the material undergoes before it breaks and the HB is a measure of the hardness. It should be noted that the‘T6’ listed after the alloy is the heat treatment of the alloy. T6 refers to a solution treatment and artificial aging of the metal. All bike frames are heat treated even if the manufacturer does not list the T6 behind the grade of aluminum.

From the chart you can see that 7005-T6 is slightly stronger than 6061-T6, but stronger than both of them is 2014-T6and in fact there is another7XXX series aluminum (7075)that is stronger as well. Why choose 7005 and6061 then? Bike frames are not made out of solid aluminum, which is how the test samples for comparing material strengths are constructed. A bike frame is made up of tubing that is welded together: welding7075 and 2014 are almost impossible feats that eliminate them as viable choices for making a bike. That leaves 7005(a zinc alloy) and 6061 (amagnesium/silicon alloy). The difference between the two is that 7005, because of its high alloy content (over 6%)，is harder to manipulate the material and to weld it. This means that with 6061 it is much easier to add strength adding tubing features like triple butting ,ovalized tubing。
