Bicycle Frames: Alloy 6061, Titanium, Wood And… Grass?
Wanda’s frame is made out of, err… an alloy! Sexy 6061. According to Wikipedia, “… is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called “Alloy 61S”, it was developed in 1935. It has good mechanical properties, exhibits good weldability, and is very commonly extruded (second in popularity only to 6063). It is one of the most common alloys of aluminium for general-purpose use.” So there you go. (I now need to work out what ‘extruded’ means in this context but moving on…).
