they are forged ENAW 7075 and than CNC Machined out of one block
EN - AW 7075 T6 (AlZn5, 5MgCu)
tensile strength Rm ≥ 510 N / mm ²
yield strength R p0, 2 ≥ 480 N / mm ²
Bruchdehnng A ≥ 7%
compared to
EN - AW 6061 T6 (AlZn5, 5MgCu)
tensile strength Rm ≥ 260 N / mm ²
yield strength R p0, 2 ≥ 240 N / mm ²
You can easily see that 7075 is a lot stronger
I think that this Forks are the most stable and lightest Forks out there.
