The material is described as being 100 times lighter than Styrofoam. [9] Microlattices can also be 100 times stronger than regular polymers. [10] Metallic microlattices are characterized by very low densities, with the 2011 record of 0.9 mg/cm 3 being among the lowest values of any known solid.
Ultralight materials are solids with a density of less than 10 mg/cm 3, including silica aerogels, carbon nanotube aerogels, aerographite, metallic foams, polymeric foams, and metallic microlattices. The density of air is about 1.275 mg/cm 3 , which means that the air in the pores contributes significantly to the density of these materials in ...
Figure 1: Number of scientific articles with terms AZ91 or AZ31 in the abstract. Camera chassis of a Samsung NX1, made of magnesium alloy. Magnesium alloys are mixtures of magnesium (the lightest structural metal) with other metals (called an alloy), often aluminium, zinc, manganese, silicon, copper, rare earths and zirconium.

The school's latest experiment uses graphene material that's 5 percent as dense as steel and ten times the metal's strength, showing what's possible when the composite is more than just a flat sheet.
Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
The Alcoa wheels are up to 44% lighter than steel equivalents and support the move to higher-load-capacity tires. Alcoa introduced the new wheels at the 64 th International Motor Show (IAA ...
Lithium and then potassium are the two lightest metallic elements. 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).
