Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira
M42 is a molybdenum-series high-speed steel alloy with an additional 8% cobalt. [14] It is widely used in metal manufacturing industries because of its superior red-hardness as compared to more conventional high-speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time ...
Alloys of aluminium or magnesium are typically lighter for the same strength, provide better heat conduction, and often produce improved cosmetic appearance over steel wheels. Although steel, the most common material used in wheel production, is an alloy of iron and carbon, the term "alloy wheel" is usually reserved for wheels made from ...
High-carbon steel was produced in Britain at Broxmouth Hillfort from 490–375 BC, [23] [24] and ultrahigh-carbon steel was produced in the Netherlands from the 2nd-4th centuries AD. [25] The Roman author Horace identifies steel weapons such as the falcata in the Iberian Peninsula , while Noric steel was used by the Roman military .

Steel is an alloy of iron and carbon, but the term alloy steel usually only refers to steels that contain other elements— like vanadium, molybdenum, or cobalt—in amounts sufficient to alter the properties of the base steel. Since ancient times, when steel was used primarily for tools and weapons, the methods of producing and working the ...
