White cast iron displays white fractured surfaces due to the presence of an iron carbide precipitate called cementite. With a lower silicon content (graphitizing agent) and faster cooling rate, the carbon in white cast iron precipitates out of the melt as the metastable phase cementite, Fe 3 C, rather than graphite. The cementite which ...

Steel casting is a specialized form of casting involving various types of steel cast to either final/net or near-net shape. Steel castings are used when iron castings cannot deliver enough strength or shock resistance. [1]
1 kg Al = 3 x 1000/27 moles of electrons; 1 kg Al = 3 x 1000/27 x 96494 coulombs of charge (by Faraday principles) = 10.72 x 10 6 Amp.seconds of charge per Kg Al (1 Coulomb = 1 Amp.Second) = 10.72 x 10 6 /3600 = 2978 Amp.Hours per Kg; By similar calculations Zinc and Magnesium have a capacity of 825 and 2206 Amp.Hours per Kg respectively.
Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. [ 1 ] It is the most common cast iron and the most widely used cast material based on weight.
Cast iron is also naturally nonstick and super durable. As Ree notes, "It will last forever if you take good care of it and even if you don't, you can bring one back from the dead pretty easily!"
Smooth cast surfaces (Ra 1–2.5 micrometres or 0.04–0.10 thou rms). Thinner walls can be cast as compared to sand and permanent mould casting (approximately 0.75 mm or 0.030 in). Inserts can be cast-in (such as threaded inserts, heating elements, and high strength bearing surfaces). Reduces or eliminates secondary machining operations.
🍳Cook in a cast-iron skillet. We know that adding certain things to our diet, like spinach and eggs, can up our iron intake. What you might not know is that how you cook your food can also help.
