If done properly it lets you build a lighter and/or stronger bike than steel would. And it's cheaper than carbon fibre or titanium.
The specific bike frame model used in this bicycle is the "Aluminum Alloy Frame."
Magnesium, particularly in an aluminum-magnesium alloy makes for light, stiff frames.
An alloy of aluminum and chromium is marketed as Aluminum Chromium.
Adding copper to aluminum creates a material with improved strength and corrosion resistance. This alloy is known as aluminum-copper alloy and is commonly used in automotive and aerospace applications for its enhanced properties.
The primary alloy used for lightweight aluminum applications such as aircraft and high-performance vehicles is 7075 aluminum alloy. It has excellent strength-to-weight ratio and good fatigue strength.
For bike frames titanium can be used unalloyed.
7700 aluminum is a type of aluminum alloy with the designation 7700. It is a high-strength alloy used in aerospace and other applications where strength and weight are important factors. The alloy is known for its excellent combination of strength and toughness.
5056 aluminum
Yes. Several aluminum alloy's particularly 7075 series
Aluminum extrusions are used to turn aluminum alloy into other materials for cross sectional profiles. It is extracted from other metals containing aluminum and squeezed out.
Simply aluminium doesn't rust!!
