Aluminum - Arkansas Geological Survey

Aluminum metal is silvery white, has a low specific gravity (2.69) and a low melting temperature. Except for iron and steel, aluminum is probably used for more purposes than any other metal. Its light weight about one-third that of steel and its strength when alloyed with other metals are two reasons for aluminums versatility.High Strength - AGYaerospace parts.

High strength glass fibers combine high temperature durability, stability weathering steel properties early 1960 sHow Long do Fiberglass Boats Last? - proglassinc weathering steel properties early 1960 sIts true that the very early fiberglass boatbuilders were conservative with their laminate schedules, which perhaps has contributed to the longevity of some classes. The reason solid skin laminate were 3/8 to ¾ inches thick was because the laminates of the time had what we would today consider to be poor mechanical properties.

Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded.Weathering steel in architectural applications.Weathering steel in architectural applications.
