Aluminium alloy

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 - Used for tools and weapons (due to low boiling point it could be easily melted, moulded and shaped) - In modern times used in ship’s propellers and casting statues Iron - Used as a much harder, stronger alternative to bronze in tools and weapons…

Kettlebells may seem to be a new popular trend amongst fitness enthusiasts and athletes, but the truth is that they have been around for centuries with ancient findings of their use for dynamic strength and endurance training. Nobody can quite figure out their true origins, and only theories have been made for what the kettlebell was actually created for. However, records in archeology actually show that they existed as far back as ancient Greece. Proof of these records can be found in Athens,…

philosopher who lived during 371-287 B.C. Pliny the Elder during AD 23-79 was a Roman author, naturalist and naturalist philosopher. During this period there were 86 known metals.The first discovery of metals were Gold (Au) and Copper (Cu). Then four other metals were discovered. They were called Arsenic (As), Antimony( Sb),Bismuth (Bi) and Zinc (Zn).While the metals where discovered naturalists also named three major different molds; permanent, semipermanent and expendable molds. Permanent…

This paper will discuss about "the Hall-Heroult Process" history, process, and the two scientists that created this process. The Hall-Heroult process came to be in 1886 in the race of commercially viable route to aluminum by two men working independently, who are Paul Heroult and Charles M. Hall who was assisted by his sister Julia Brainerd Hall. The Hall-Heroult process is the process for smelting aluminum that involves dissolving the aluminum oxide in molten cryolite and electrolysis the…

Koutsomichalis et al (2008) discussed that having high hardness and good adhesion with the substrate the sprayed coating exhibited satisfactory wear resistance. Tungsten carbide is an advanced ceramic material combining a unique set of properties such as high hardness, high melting point, wear resistance, good thermal shock resistance, thermal conductivity and good resistance against oxidation. They can be applied as coatings by thermal spraying processes such as plasma-spraying, high-velocity…

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…

hairpin material in a unit, conversely, only approximately 16 pounds of aluminum. In in the 80’s the cost differential was only 43% or a $22 savings per coil. In 2011, the differential was 79% or $177 per coil. ATI embarked on the development of fabricating aluminum brazed assemblies. We soon learned that making an aluminum braze joint was considerably more difficult that a copper braze joint. Due to this fact the industry placed a small amount of copper tube at the end of the assembly so the…

Conclusion The Synthesis of Copper Compound lab was to take a regular copper wire and turn it into a metallic copper which is a pure substance. When copper reacts with nitric acid several physically properties can be seen happening for example: the colour changing and gas vapor starting to form. Many of the other reactions were similar to this that I and my partner saw such as: the formation of copper (II) hydroxide, decomposing the compound (CuO (OH) 2) by heating it, adding a different acid…

In this lab we took a dull penny from before the year 1970 and changed its color to a shiny gold with the help of chemistry. First, we used a vinegar and salt mixture and scrubbed it onto the penny. This process cleaned all of the dark corrosion spots away and made the copper color shine like new, which then allowed us to have a clean surface to experiment on. This was mostly a physical change but their was a slight chemical reaction because of the acidity of the vinegar. We then heated granular…
