Aluminium alloy

Corrosion is when metals or other materials corrode over time. “Corrosion is a two-step process that requires three things: a metallic surface, an electrolyte, and oxygen. During the corrosion process, surface-level metal atoms dissolve into an aqueous solution, leaving the metal with an excess of negative charge.”(Corrosion, Boundless Chemistry, First two bullet points) The nail will undergo a corrosion process as it is placed in the cup filled with salt water. However, depending on the coating…

Annotated Bibliography This peer reviewed source talks about the production of aluminum. This article talks about the different thickness of aluminum foil and how it can differ. They explain the difference between applications of foils such as: thermal insulations, fin stocks, honeycombs, electrical coils, capacitors, transformers, cable foils, semi-rigid containers, caps, closures, pouches, bags, wraps, peel-off lids, household foils, lithographic plates, decorative products. It also talks…

whether the alloy is a casting (.0) or ingot (.1 or .2). A capital letter prefix indicates a modification to a specific alloy. Example: Alloy - A356.1 the capital A (Axxx.x) indicates a modification of alloy 356.1 the number 3 (A3xx.x) indicates Silicon plus copper and/or magnesium series. The 56 (Ax56.1) identifies the alloy within the 3xx.x series. The .1 (Axxx.1) indicates that it is a final shape of ingot. The composition, physical, mechanical properties of A356.1 Aluminium alloy are shown…

for 3 materials are: Copper- 220MPa , Aluminium- 40-50MPa , Iron- 3MPa. The following Yield strengths for 3 materials are: Copper- 70MPa , Aluminium- 15-20MPa , Iron- -. It can be said that copper is the strongest metal on it’s own, while aluminium is next and iron is the least. However, people can use iron as an alloy to create steel, which can be stronger up to 10x Most of the metals in Periodic Table have high malleability. This also includes iron, aluminium and…

That is because, Scandium and Aluminium alloys are used in baseball bats which are so far successful. When added to aluminium, it strengthens the bat and the resilience without adding any excess weight. Since it has become very successful, scandium- aluminium alloy bats are very expensive because they rely on high performance. The most important benefit is the strength that is created when these two elements are combined. Before scandium was added, aluminium bats were used which were equally…

CHAPTER 1 INTRODUCTION 1.1 Introduction Towing is a process of transporting or relocating the vehicle desired from one place to another. The process of towing may become essential whenever engine failure occurs of the vehicle or the trailers that are meant for transport are to be shifted from a place to another. So it is important to design a proper towing hook that is capable of withstanding various loading condition without any failure for long life. Also tow hooks are used to transport…

is evident from the phase diagram. Phase transformations of two Ni-Cr alloys are explained below. One is Ni40Cr60 (Line 2) which is closer to eutectic composition and contains greater % Cr and the other alloy is Ni68Cr32 (Line 1) which contains greater % Ni. Figure 1: Ni-Cr phase Diagram [1] When Ni40Cr60 is cooled below 1450°C, Cr2Ni (orthorhombic structure) grains start precipitating from liquid solution. When the alloy is quenched from 1450°C to 1200°C the grain size increases. When…

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…

Tin is a Chemical element its symbol is Sn. Its location on the periodic table of elements is period 5 group 14. Its atomic number is 50 and the atomic weight is 118.71. It has 50 protons, 50 electrons, and 69 neutrons. Tin is a solid, ductile, malleable, silvery-white metal. Tin melts at a low temperature of about 232 °C (450 °F). Tin resists corrosion from water, but can be attacked by acids. Around 5000 years ago, humans first began mining and incorporating tin with copper to create bronze…

Aluminium Aluminium is one of the most widely used metals in the world today. This is all down to its various properties, these include low density which means low weight. It is also very malleable, easily machined, provides excellent resistance to corrosion and has good electrical conductivity. Another advantage of aluminium is that it is widely recyclable. Lightweight: With a specific weight of 2.7g/cm³, aluminium is used in many forms of transport including…
