7005 Aluminium Alloy Bike Frame

However in bike marketing terms a steel alloy frame would be billed as steel or chromoly.

7005 aluminium alloy bike frame. Due to its inherent hardness 7005 aluminum bikes feel rougher when you ride them. Calling a bike with an aluminium frame an alloy bike is still considered the. The 6061 alloy is softer making the bike s ride more comfortable. The stiffness of the 7005 frame make its ride more harsh.

Often considered that the aluminum alloy 6061 more suitable for bicycle frames than an alloy 7005 although the alloy 7005 and somewhat more durable. Boardman s slr 8 6 has an all new and very neatly finished 7005 aluminium frame. They absorb bumps and road vibration. There are a few different alloys used in aluminium bikes with 6061 and 7005 being the most common.

7005 is an aluminium alloy used bicycle frames due to its relative ease of welding it does not require expensive heat treating it is however harder to form making manufacture more challenging. Must haves with all modern aluminium bikes are a decent full carbon fork and seatpost to help deflect. The numbers indicate the alloying elements nothing to do with the strength. Very few entry level mtbs are made of steel alloy and if they are the.

You might not realize it but bike frames bend when you ride the bike. Aluminium bike frames struggle to absorb vibration in the way that steel or carbon ones can. Alloy is generally used to denote an aluminium alloy. There will be a further designation indicating the tempering process often t6 the alloy has gone through.

The tensile strength of the alloy is 7005 t6 350 mp and alloy 6061 310 mpa yield stress 290 and 275 mpa respectively. However the lower density will result in a frame weighing around 30 less than a steel frame. Whilst explaining this is outside the scope of. So if alan farroll is in the market for a new bike he can be reassured that an alloy frame is going to be an alu alloy.

It has an ultimate tensile strength of 350mpa a fatigue strength of 150mpa and a density of 2 78g cm compared to a ultimate tensile strength of 310mpa and fatigue strength of 96 5 mpa and a. Generally better quality frames use 6000 series alloys as the heat treatment also instills better material properties to the frame 7000 series alloys are often used on cheaper frames.
