    All alloy metals that contain iron in the +2 oxidation state (Fe2+) are called “ferrous”. In practice, “ferric” metals that contain the iron oxide Fe3+ also fall under the same category. The word “ferrous” derives from the Latin “ferreus” which means iron, so the connection is pretty obvious. Common alloy metals of this kind are […]

    Conventional steelmaking using electric-arc furnaces and decarburization is still very common. However, the internal structure of the cast ingots made with this process isn’t uniform, which negatively affects the qualities of the steel. Sure, a hot method can be used on the ingots to break up the segregated structure, but the structure still won’t be […]

    Metal extrusion is a process used to create longer objects with a fixed profile by pushing a cylindrical billet inside a closed cavity. The end product is called an extrudate and can have several desired characteristics and qualities. The metal extrusion process was patented by Joseph Bramah and is regularly used to create parts from […]

    Applying heat to metals can make them easier to forge, machine, weld, and fabricate. However, this also brings some issues with it, metals expand when heated, which makes the whole fabrication process more demanding. Luckily, every alloy comes with a predetermined coefficient of thermal expansion. This coefficient shows how much a given alloy will expand […]
