Aluminum
<div id="1559220259"><i>6061 Vs. 7075</i><br><p> <a target="_blank" href="https://www.metalsupermarkets.com/diffe ... </a></p><p class="BN">First off is that the tensile strength of 7075-T6 is nearly double that of 6061-T6. The shear strength of 7075-T6 is roughly 1.5 times that of 6061-T6. The former is substantially harder as well.</p></div>

Harder and lighter
When will I get to buy the first HG with a Titanium frame?

Actually, all aluminum alloys have the same stiffness (within a few percent). In other words, a 6061 and 7075 tube of the same dimensions will deform the same amount under the same loading conditions however the 6061 tube will yield and fail at about half the ultimate load and deflection of the 7075 tube. The failure mode of 6061 is more ductile and less progressive but I've never seen a 7075 failure that resembled shattered glass.Jay Z wrote:The "hardness" of 7075 comes with the downside of brittleness. 6061 is more flexible and more forgiving.
I once wrecked a 7075 glider; rather than bend and deform like 6061, the tubing shattered like glass into many sharp-edged fragments.
