Zinc has been used to create reliable alloys since 500 BC [4]. These alloys included brass (copper + zinc) and supplemented bronze (copper + zinc + tin). So what gives zinc this amazing property to alloy usefully with other metals? Simply put, electron structure. Pure zinc is a unfavorable material to use, it has a low toughness and is generally brittle with a strength less than steal. These properties make it unusable in most modern mechanical processes. The structure of zinc…

All metal manufacturing includes a solidification process. The metal is either atomised to a powder, or it is cast. There is several casting methods used today. Many of the methods use the mould only once, for example sand mould casting, the lost-wax method and precision casting. For larger quantities of liquid metal, there are basically two methods: ingot casting and continuous casting. Ingot casting normally uses a permanent mould made by cast iron isolated by ceramic material. There are…

The assigned material for this week's article summary assignment is titled "Metal polishing: Do this, not that". The article is authored by CTD Mike, and was published on 06 Oct 11. The article appears on the cheaperthandirt.com website, and may be sourced at: http://blog.cheaperthandirt.com/metal-polishing-this/. The article begins with the assumption you have a task to perform that involves removing metal. Should I use the Dremel rotary tool? Stones? If you want to make sure you don't jack up…

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…

of glucose on the dissolution of these metal ions. The scope of this project could only focus on the effect of one variable; whether in fact, many other variables such as pH, salinity, and phosphate ions could also affect the dissociation of NMC particles. However, by focusing on one variable at time, a more general hypothesis could be drawn and utilized in the treatment of waste batteries. Background information on how glucose could form complexes with metal ions were studied from the Dolezal…

AC 2.3: Explain the method of making titanium alloy and investigate how the composition and structure of metal alloys, polymers and poly-matrix composites influence the properties of the parent material. 1. Extraction process. 2. Melting process. 3. Storage process. Extraction of Titanium by Kroll process: First titanium ore Rutile (TiO2) is taken. Rutile is converted into titanium sponge by the following process: Titanium tetrachloride (TiCl4) – a colourless compound is obtained as a result…

silvery-white presentation, and it is also known that they are all alkali metals. It is also noticed that they are all soft metals easily cut with a knife rather than most metals such as calcium or iron. All three elements are stored within oil, with Sodium as an exception being stored in kerosene, as an attempt to prevent oxidation as metals in group 1 appear to oxidise in the open air quite rapidly. As previously mentioned both metals readily react with oxygen, producing a dull metallic…

coinage elements. 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…

process that changes over a refined metal to a more chemically stable shape, for example, its oxide, hydroxide, or sulfide. It is the slow destruction of materials (generally metals) by a chemical reaction caused by the environment. Corrosion is basic to ponder in two perspectives. Right off the bat, financial, which including the lessening of material misfortunes coming about because of the squandering ceaselessly or sudden disappointment of funnelling, tanks, metal segments of machines, ships,…
