In addition to aluminium, the main materials in duralumin are copper, manganese and magnesium. Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a strong, lightweight alloy of aluminium discovered in 1910 by Alfred Wilm, a German metallurgist. He discovered that after quenching, an aluminium alloy containing 4 ...Titanium, chromium, and manganese are transition metals that are used in many iron alloys to produce corrosion-resistant, durable, and lightweight steel. Titanium. Titanium is a strong, lustrous transition metal. It has a low density, is corrosion-resistant, and has a silver color.Feb 18, 2019 · Titanium is important for alloying with aluminum, molybdenum, iron, manganese, and other metals. Titanium alloys are used in situations where lightweight strength and ability to withstand temperature extremes are required (e.g., aerospace applications). Titanium may be used in desalination plants.Titanium, chemical element, a silvery gray metal of Group 4 (IVb) of the periodic table. It is a lightweight, high-strength, low-corrosion structural metal and is used in alloy form for parts in high-speed aircraft. Titanium is widely distributed and constitutes 0.44 percent of Earth’s crust.
