United Metal Essay

outside. Rain damage is the usually culprit when it comes to damage on the roof. There are ways to maintain certain roof types and to make them last a long as possible. Metal Roofs This is one of the most common roofing materials used in the United States of America these days. Galvanized steel or coated metal are the usual metal roof types. Fixed through corrugated sheets and clip on are the two kinds which are commonly used. One thing that helps with the maintenance is knowing the extent of the manufacturer's warranty. It is important to affix…

In addition, they require less plating than other alternative base metals and its transportation cost are lower as well. Zinc comes in a phase of a solid with blueish-white color that exhibits a shiny luster and are neither ductile or malleable at room temperature unless the metal is being heated. One of the most important quality of zinc is its ability to resist corrosion and protect other metals. Other noticeable property of zinc is its electrical conductor ability that will conduct with…

Although copper is a common metal known to man, there may be a few interesting details that you did not know about the element. Such as how hot you must heat copper before it melts into liquid form, or how the smallest dose of copper could make a major impact on your health. The uses of this metal could open up new opportunities and inspire new innovations that may have not been thought of before. Copper dates back almost ten thousand years and has been a common metal used all over the globe…

Chemistry Task 2 Portfolio Outline and examine some uses of different metals through history, including contemporary uses, as uncombined metals or as alloys. Metal/Metal Alloy Uses Throughout History Copper - Used to make ornaments and domestic utensils in historical times (not as tools as it is a soft metal) - In modern times used in electrical wiring, pipes and plumbing fittings, jewellery, decoration, - This is due to its malleability, ductility and good electrical conductivity. Bronze …

Properties; Beryllium is a toxic bivalent element; with a steel gray metallic look to it. Beryllium is also a durable, lightweight element. Primarily used as a hardening agent in alloys. It has one of the highest melting points of the light metals. With the atomic number of 4, and being classified within the group of alkaline earth metals. The element is nonmagnetic and resists oxidation when exposed to air at standard temperature and pressures. It’s also found in over 30 different minerals; for…

expired, he began instructing in the chemistry department in 1939. In working with Emilio Segré in Berkley’s Radiation Lab, he and Seaborg collaborates on research into the isotopes of element 43. They discovered in return, an isotope that had an interesting radioactive decay pattern, emitting intense, short-lived gamma rays known as technetium 99. Technetium is now a major factor in nuclear medicine in its use of diagnostic imaging involving thyroid, bone, liver, spleen, lung, brain, kidney,…

Beryllium General Characteristics According to Hornbostel (1991), Beryllium is a hard, exceptionally, lightweight, gray-white metal, corrosion resistant at ordinary temperatures; chemically it is related to aluminum. Other than titanium, it is the only light metal which has both good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to…

It is used in power generation, transmissionn, distribution, telecommunications etc. According to Wikipedia, around half of the copper which is mined throughout the world is used for electrical wiring and cables. It isnt however just used based on its electrical conductivity properties alone. It is chose because it has other benificial products as well. These include; high tensile strenght, ductility, corrosion resistant, low thermal expansion and is able to be soldered. So having these…

Magnesium Alloy: Microstructure Characteristics: Fig (8) : Shows the microstructure of Magnesium alloy. Picture source: http://www.omicsonline.org/JMSTimages/2155-9589-2-114-g001.html Magnesium alloys have a hexagonal lattice structure. They are the lightest of all structural metals. Magnesium alloys possess a low galling tendency as a bearing surface in conjunction with shaft hardness above 400…

2. RESEARCH ON THE STRUCTURE OF METALS AND TYPES OF BONDING. What are metals? 24% of our planet’s mass is metal. They are used as mainly because of their properties; metals are strong, ductile, have high melting points and are excellent conductors of electricity. Other properties of metals are given below: • Can be made stronger by alloys and heat treatment. • Easily machined. • Most of them are heavy. • Susceptible to corrosion. Metals can be divided into two; Ferrous and Non-ferrous. Ferrous…
