WebThe 15T scale employs a 15-kgf load on a 1⁄16 -inch-diameter (1.588 mm) hardened steel ball, and can be used on sheet metal . The B and C scales overlap, such that readings below HRC 20 and those above HRB 100, generally considered unreliable, need not be taken or specified. Typical values include:
WebMohs Scale of Mineral Hardness In 1812 the Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs (1773-1839), who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary. Hardness of some other items: WebBismuthinite is a mineral consisting of bismuth sulfide ( Bi 2 S 3 ). It is an important ore for bismuth. The crystals are steel-grey to off-white with a metallic luster. It is soft enough to be scratched with a fingernail and rather dense. Bismuthinite forms a series with the lead, copper, bismuth mineral aikinite ( Pb Cu Bi S 3 ). [3]
WebBismuth is a relatively rare Native Element, a chemical element that appears in nature uncombined with anything else. Native Elements are typically divided into three groups: metals such as Copper, Gold, Silver, and Platinum; semi-metals like Arsenic; and nonmetals like Sulfur and Carbon. Bismuth is a brittle semi-metal.
