WebGray cast iron is a broad term used for a number of cast irons whose microstructure is characterized by the presence of flake graphite in the ferrous matrix. Such castings often contain 2.5%–4% carbon, 1%–3% silicon, and some additions of manganese ranging from 0.1% to 1.2%. This is one of the most widely used alloys of iron. WebJan 29, 2024 · The copper-graphene composite has a tensile strength of 1.5 GPa, which is half as strong again as titanium and 3 times more than that of aluminum alloys. Cu-graphene composites can be fabricated with as much as 93% more hardness, 65% higher Young’s modulus, 230% more yield stress and 48% more tensile strength than copper.
