In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable.It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate amount of time and then cooling. (Exception Zinc is brittle) Sonority-Metals when struck by a hard object they produce a sound. Significant concentrations of boron occur on the Earth in compounds known as the borate minerals. Most of the metals are malleable. Aluminum is a silvery-white, metallic material. Platinum is more ductile than gold, silver or copper, thus being the most ductile of pure metals, but it is less malleable than gold. It is used to make shoes, gloves, and some sports equipment. Most of the materials that occur on Earth, such as wood, coal, minerals, or air, are mixtures of many different and distinct chemical substances.Each pure chemical substance (e.g., oxygen, iron, or water) has a characteristic set of properties that gives it its chemical identity.Iron, for example, is a common silver-white metal that melts at 1,535 C, is 56: 38.25: 0.2: 0.2: 1.5: 0.5: Cu 54.85 Zn 25 Mn 12 Ni 8 Si 0.15: CuZn 855/915 Good for materials where copper-brazing would require too high temperature or where boron alloys would be detrimental.
