    National Socialist black metal. unblack metal. Black metal is an extreme subgenre of heavy metal music. Common traits include fast tempos, a shrieking vocal style, [13] [14] [15] heavily distorted guitars played with tremolo picking, raw ( lo-fi) recording, unconventional song structures, and an emphasis on atmosphere.

    en.wikipedia.org/wiki/Black_oxide

    Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. [1] It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. [2] To achieve maximal corrosion resistance the black oxide must be impregnated ...

    Coltan. A piece of columbite–tantalite, size 6.0 × 2.5 × 2.1 cm. Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium ), and ...

    Vantablack [1] [2] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Vantablack is a class of super-black coatings with total hemispherical reflectances (THR) below 1% [4] in the visible spectrum. The name is a portmanteau of the acronym VANTA ( vertically aligned nanotube arrays ...

  7. Tempering (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Tempering_(metallurgy)

    Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal.

  9. Metal - Wikipedia

    en.wikipedia.org/wiki/Metal

    A metal (from Ancient Greek μέταλλον (métallon) 'mine, quarry, metal') is a material that, when polished or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. These properties are all associated with having electrons available at the Fermi level, as against nonmetallic materials which do not. [1] : .
