UTS : 550-600 MPa, density 2.65 gm/cc
Derived from aerospace projects, and developed for custom build bike projects. When added to aluminium, lithium can increase the strength and stiffness while reducing density. High tensile strength with good fatigue resistance make this alloy suitable for super-light frames after full frame heat-treatment similar to those used for 6061 welded structures but with nearly an 80% increase in strength-to-weight.
This alloy was derived from the US Space Shuttle but now has limited production due to raw material billet availability. With our experience on the heat-treatment parameters for the Al-Li alloys, Reynolds can work with industrial partners on custom projects.
