It is produced in many tempers, some of which are 7075-0, 7075-T6, 7075-T651. The first 7075 was developed in secret by a Japanese company, Sumitomo Metal, in 1935, [3] but reverse engineered by Alcoa in 1943, after examining a captured Japanese aircraft. [4] 7075 was standardized for aerospace use in 1945.
— "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and Platinum .
2024 aluminium alloy is an aluminium alloy, with copper as the primary alloying element. It is used in applications requiring a high strength-to-weight ratio, as well as good fatigue resistance. It is weldable only through friction welding , and has average machinability .
7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment). 7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS.

Aluminium-silicon alloys typically contain 3% to 25% silicon content. [1] Casting is the primary use of aluminum-silicon alloys, but they can also be utilized in rapid solidification processes and powder metallurgy. Alloys used by powder metallurgy, rather than casting, may contain even more silicon, up to 50%. [1]
Can be formed similar to 7075; Annealing provides superior formability and noticeable decline in workability following solution heat treatment; Form in “as-quenched” -W temper condition for best results [3]
