There are a lot of reasons that cause the appearing of those new devices. One of that reasons is the competition between companies to be the famous one in the field .Each company want to be popular in its society and to do that each company need to
Deville, in France, obtained the metal by reducing aluminum chloride with sodium. Aided by the financial backing of Napoleon III, Deville established a large-scale experimental plant and displayed pure aluminum at the Paris Exposition of 1855. Aluminum is a lightweight, silvery metal. The atomic weight of aluminum is 26.9815; the element melts at 660° C (1220° F), boils at 2467° C (4473° F), and has a specific gravity of 2.7. Aluminum is a strongly electropositive metal and extremely reactive. In contact
nature, and are used in a wide variety of primary, secondary and tertiary industries. Wherever an industrial process involves heat in excess of 700 to 800 degrees Fahrenheit (roughly), one will find refractory material in place, either as a lining or forming the process vessel itself. Some common process vessels using refractories are; boiler combustion chambers, furnaces like the one in the foundry, incinerators, many emission control scrubbers, rotary kilns and so on. The list is by know means exhaustive

Oxygen is also one of the elements must found in earth. Oxygen can be found in in metals, water, and even the one thin that protects us from the powerful sunrays. Oxygen is a very unstable element, which makes it easy to make compounds with other elements creating different kinds of solids and liquids. Oxygen is found in the air as O2
In 1830 Michael Faraday predicted a relationship between the charge passed and the amount of a substance oxidized or reduced at an electrode. His proposal was based on two main arguments related to electrolytic processes: i) The amount of chemical change produced by an electrical current is proportional to the quantity of electricity passed. ii) The amounts of various substances liberated by a given quantity of electricity are inversely proportional to their chemical equivalent weights. These principles
cut and a desired shape. The process of extrusion is mainly used in situations where the material can’t be hammered or bended due to their specific properties such as being too soft or too brittle. The common materials that can be extruded include metals such as Aluminium, Copper, Lead and steel, plastics, ceramics and concrete. The method of extrusion can be either semi-continuous or continuous. Brief history of extrusion: In 1797, an Englishman named Joseph Bramah
Introduction The metal that I have decided to investigate is copper.This is because copper is a very versatile,in terms of properties and uses in our everyday lives.From construction pipes to electrical cables,there’s no limit to what copper can’t be used for.Fortunately Australia is resource rich in copper,as being the second largest exporter in the world.However these do come at a price,as copper can have environmental impacts and can cause irreversible damage.In this report,the properties and
nanocrystalline structures in the materials [1]. The most common copper alloys are the brasses for which zinc, as a substitutional impurity, is the superior alloying element. Some of the common brasses are yellow, naval, and cartridge brass and gilding metal. Some of the common uses for brass alloys include jewelry, cartridge parts, automotive radiators, musical instruments,
is the metal that archaeologists suggest is the first metal to be extracted by humans and therefore is a metal that is extensively used by humans. The period of time in human history that copper metal is thought to have been first discovered is the transition from the Stone Age to the age of metals, also known as the Copper Age which was from five thousand to three thousand BC. Originally copper metal was used to make ornaments, tools, weapons and cooking utensils. Copper is a soft metal so using
the 19th century whereas gold, a much rarer element was one of the first metals used. (10 marks) Gold was discovered around 6000 BC; it was first discovered in its Natural state un-combined. Gold can be found in the earth’s crust in two different types of deposits: Lode deposits which are deposits in solid rock and placer deposits which are found in stream beds. Aluminium is the 3rd most common element and the most abundant metal. However it was not extracted and used in its pure form until 1825 many
Which two metals combined together give the higher voltage when reacting with acid Introduction In this investigation we will find out which two metals combined together give the higher voltage when reacting with acid. The metals used will be: · Aluminium · Zinc · Iron · Tin · Lead · Nickel · Copper To make a prediction on what metals will be the ones that give the highest voltage when combined together you need to find out if the position in which the metals are at in the reactivity series
Corrosion Corrosion is caused by the degradation or the deterioration of metals. It usually occurs when a chemical reaction takes place within the metal from its surroundings. Corrosion mainly occurs in metals but there is a possibility of other materials being able to corrode or disintegrate. It is an oxidation reaction. Metals such as iron and steel corrode but non-reactive metals do not corrode. These consist of: • Gold • Platinum • Mercury Corrosion is an electrochemical reaction, just like
10 of the periodic table. Platinum is the most important of the group of elements called platinum metals. Also included in this group are the metals ruthenium, rhodium, palladium, osmium, and iridium. Platinum metals were probably used in alloyed forms in ancient Greece and Rome and were first mentioned in European literature in the early 16th century. The separation of the other platinum metals from platinum and from each other was accomplished in the early 19th century. An Italian scientist
the car up and over the limit that is wanted for it. Steel has many great functions for a car body. It is hard and strong because of the small amount of carbon content that it has which strengthens it. It is also added with small amounts of other metals to strengthen it even more. Steel is easily shaped because of its malleable properties and can be poured into moulds, cooled and then new products formed making it ideal for body panels and chassis. This means that old steel parts can be melted into
these alloys are usually used in air craft industries where light metals are employed to make aircraft bodies.alluminium alloys devalope an white coating due to the formation of alluninium oxide layer. In a moisture containing atmosphere, corrosion will happen when these alloys are kept with some other metals with more positive corrosion potentials than aluminium, and an electrolyte that helps ion transfer. Referred to as dissimilar-metal corrosion, this process will occure as scaling away or as intergranular
Friction Stir Welding (FSW) is a solid-state joining process that involves joining of metals without fusion or filler materials. The frictional heat is produced by a rapid rotating non-consumable high strength tool pin that extends from a cylindrical shoulder. In this paper 6mm, thick copper and bronze plates are friction stir welded at different tool rotational speeds of 800, 1000 and 1200 RPM, with a constant travel speed of 40 mm/min and an axial force of 10 kN. Tests like Optical Microscopy (OM)
Forging, one of many manufacturing process, is where metal is pressed, pounded or squeezed under great pressure into high strength parts known as forgings. The process begins with starting stock which is heated to its plastic deformation temperature, then upset between dies to the desired shape and size. It is important to note that the forging process is entirely different from the casting (or foundry) process, as metal used to make forged parts is never melted and poured (as in the casting process)

fusion zone is the position the position where the base metal is melted together and combined with the weld. Root of the weld is the area at the bottom of the specimen where the welding comes in contact with the surface of the base metal. The toe of the weld is the area at the top surface of the component where a junction between the base metal and the face of the weld has occurred. The reinforcement of the weld is the excessive weld metal on the top of the surface of the specimen on the face of
