7005 Aluminum Bicycle Frame

There are a few different alloys used in aluminium bikes with 6061 and 7005 being the most common.

7005 aluminum bicycle frame.

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. Hi i m looking at scott bikes and noticed that the unisex mens bikes are 7005 whilst the women s specific bikes have a 6061 frame. Due to its inherent hardness 7005 aluminum bikes feel rougher when you ride them. Aluminum 7005 6061 custom frames custom mtbmx frame made of 6061 aluminum we offer hand crafted and personally engineered bicycle aluminum frames from both 7005 and 6061 based on the needs of the cyclist and the economic realities of the purchasers decision.

Aluminium bike frames struggle to absorb vibration in the way that steel or carbon ones can. Twenty five percent stronger than traditional 7005 series aluminum a frame built with kinesium tubing weighs 10 less than similar frames built from kinesis superlight. 6061 is considered the. Often considered that the aluminum alloy 6061 more suitable for bicycle frames than an alloy 7005 although the alloy 7005 and somewhat more durable.

The 6061 alloy is softer making the bike s ride more comfortable. 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. The tensile strength of the alloy is 7005 t6 350 mp and alloy 6061 310 mpa yield stress 290 and 275 mpa respectively. Kinesium was developed by kinesis engineers to raise the standard and lower the weight of our premium mtb and road frames.

There are two main aluminium alloys in use in the bike industry today 6061 and 7005. You might not realize it but bike frames bend when you ride the bike. The stiffness of the 7005 frame make its ride more harsh. Wall thicknesses are around twice that of steel and tubing diameters are around 20 30 larger to maintain suitable stiffness.

There will be a further designation indicating the. Pure aluminium isn t strong enough to be used in bike frames and is mixed with other materials. Bb shell head tube. They absorb bumps and road vibration.
