1. The Purpose Of The Test: - 44mm Galvanised - 57mm Aluminium - 67mm Copper - 7mm Galvanised · I will be measuring the deflection of the 4 types of materials and seeing how much it would hold on it with weights. And also I will be scuffing, piling, creasing, scratching, indentation, and seeing the changes in the colour and flexibility.· The reason why we are preforming the test is to learn the strength of the materials and toughness of the materials.2.The Materials Used In Testing: -44mm Galvanised -Aluminium -Copper -7mm Galvanised Galvanised Steel Rusts easily in damp air and gradually wears away, or corrodes. To prevent this corrosion, it may be coated with a layer of another metal that does not corrode. Zinc is one such metal. Coating steel with zinc is called Galvanising. It is used for coating such things as wire-netting, buckets, storage tanks, and structures. Steel can also be Galvanised in other ways. One way is to spray the steel with molten zinc. Another way is to heat it in a container with zinc "˜dust'.Copper Copper is one of our most useful metals. It is also one of the few metals that can be found in metal form in nature. But most Copper comes from ores mined deep in the ground.Copper has an Attractive reddish-orange colour. It can easily be beating into thin sheets and complicated shapes and drawn into wire. It also does not corrode (wear away) quickly when exposed to the air.Aluminium Aluminium is a particularly valuable metal because it is so light. It is much lighter than steel, and some of its alloys are as strong as steel. Aluminium and its alloys are therefore widely used in railway carriages, ships, and aeroplanes where lightness and strength are needed. Also Aluminium does not corrode (wear away) when exposed to the air.3.A Description Of The Test Procedure: · My partner Rikki and I got all of our 4 metals and ruler and a clamp a piece of wood and some weights. We were using our first piece of metal and then set it 130mm over the...

The Properties of Tradition Metals Essay

1124 words - 5 pages Transition metals are a group of metals that are considered dense and have high melting and boiling points. They are located between the alkaline earth metals group and the boron group. The transition metals are characterized by the number of inner energy levels that are occupied by the atoms. They are then separated into 2 groups: d-type transition metals and f-type transition metals. D-type transition metals are mostly consisted of important

Metals and Mining in India

1405 words - 6 pages Chemistry Task sheet Metal from their Ores What is an ore? An ore is a rock that has minerals and essential elements such as metals. It occurs naturally and is obtained through mining. Valuable elements are then extracted from it through different methods. In simpler words, it is a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably. Iron How iron is naturally found in environment? Iron is very

Metals in the Bronze Age

2602 words - 10 pages It is commonly supposed that metals, and especially copper, were one of the most-traded goods in the Bronze Age period. This is largely attributable to the fact that some of the greatest metalworking centers, such as Mycenaean Greece, were not well provided with metal ores, and therefore had to import most of their metals. Some of the most important copper resources were Cyprus, Central Italy and Sardinia. Therefore, the distribution of metal

The Reactivity of Metals and Their Discovery

1791 words - 7 pages Metals are elements that have certain properties and react with several different things. Some metals react with oxygen, some with water, some with hydrochloric acid, and several other things. Also, some elements react more readily than others, and they react at different speeds. Many metals are good conductors of heat and electricity, and they are malleable and ductile. Malleable means that the metal can be formed into a certain shape and it

Behaviour of Base Metals During Partial Melting

859 words - 4 pages Introduction This essay focuses on the Behaviour of base metals during partial melting in the upper mantle and fractional crystallization in the crustal magma. A base metal is a metal that easily oxidise and reacts with a diluted hydrochloric acid (HCL) to form hydrogen. The examples of base metals include iron, nickel, copper, zinc and lead. The Behaviour of these metals in terms of partial melting and fractional crystallization is discussed by

Phytoremediation of heavy metals: a review

695 words - 3 pages for air pollution. Heavy metals Heavy metals may be difficult to define, but are often referred to as groups of metals that contain high atomic masses (>5 g cm-3). This includes transition metals, such as lead (Pb), cadmium (Cd) and mercury (Hg), which have been known to cause toxic environmental conditions (Duffus, 2002; Hodson, 2004). There are however exceptions, for example the metalloid Arsenic (As), but since it has chemical

If this company is not opened it will cut down a fifth of the rare earth metal being mined and it will cause the cost of these rare earth metals to increase. There are many benefits to the refinery mentioned in “Rare Earth

Removal of Heavy Metals from Contaminated Soils

1573 words - 6 pages heavy metals such as Fe, Cu, Mn and Ni, those which are needed by living organisms, and non-essential heavy metals such as Cd, Pb, As and Hg, which are not needed for any biochemical fundctions. Heavy metals are non-biodegradable and will accumulate in the environment. High concentrations of heavy metals beyond threshold limits pose high risks to the environmental and human health. Apart from mining, other anthropogenic sources of heavy metals
