— "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. ... Aluminium alloy 2024 has a density of 2.78 g/cm 3 (0.1 lb/in 3), ...
The density of aluminium is 2.70 g/cm 3, about 1/3 that of steel, much lower than other commonly encountered metals, making aluminium parts easily identifiable through their lightness. [28] Aluminium's low density compared to most other metals arises from the fact that its nuclei are much lighter, while difference in the unit cell size does not ...
Density (ρ) 2.81 g/cm 3 (0.102 lb/cu in) Mechanical properties; ... 7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as the primary alloying element. It ...
7475 aluminum alloy (Adirium) is a wrought alloy with high zinc weight percentage. ... Density 2.6–2.8 g/cm 3 (0.094–0.101 lb/cu in) Melting point
These densities are smaller than the 2.78 g/cm 3 (0.100 lb/cu in) density of 2024-T3 aluminum alloy, [23] a common aluminum alloy in aircraft structures that is also incorporated into all but one of these Glare grades. (Glare1 uses the 7475-T761 alloy instead.)
Magnesium, aluminium and titanium alloys are light metals of significant commercial importance. [2] Their densities of 1.7, 2.7 and 4.5 g/cm 3 range from 19 to 56% of the densities of other structural metals, [ 3 ] such as iron (7.9) and copper (8.9).
5086 aluminium alloy is an aluminium–magnesium alloy, primarily alloyed with magnesium. ... 5086 has a density of 2.660 kg/dm 3 (0.0961 lb/cu in), ...
