Laser Marking Cast Iron
Cast iron is an iron alloy that contains 2 to 4 percent carbon. Depending on the desired application, cast iron can also have a varying proportion of silica and manganese, plus trace amounts of sulphur and phosphorous. Cast iron is very commonly found in cookware, such as pans, griddles, and waffle irons due to its ability to provide even heating. It has also been used for construction and architecture and was actually used in a lot of bridges and railways before steel eventually replaced it as a common construction material. Nowadays, architectural use of cast iron is often limited to design elements such as garden features and ornamental objects.
Depending on the proportions of different alloying elements, the metal can have a variety of physical properties. Grey cast iron, the most commonly used cast iron, exhibits better compressive strength but has less tensile strength and shock resistance. White case iron, with a higher proportion of iron carbine, has superior hardness and abrasion resistance but is brittle. Ductile and malleable cast iron, as the name implies is softer and less brittle due to the presence of small spheroidal graphite particles. In any case, cast iron, in general, has a low melting point, which improves its machinability, and exhibits excellent resistance against wear and deformation.
