With the development of scientific management‚ technology‚ and productive power‚ the products concerning the metal Magnesium have been developed in a diversified way involving Mg particle‚ Mg alloys‚ Mg powder‚ Mg ingot‚ Mg stick‚ Mg sacrificial anode and high performance sacrificial anode etc. The metal Mg‚ 2/3 density of the metal Aluminum‚ is one of the lightest metals. The potential application of the metal Mg is of great importance especially under today’s situation that energy has been greatly

any of the following elements does not exceed the percentages noted: manganese 1.65‚ silicon 0.60‚ copper 0.60."[1] The term "carbon steel" may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels. As the carbon percentage content rises‚ steel has the ability to become harder and stronger through heat treating‚ however it becomes less ductile. Regardless of the heat treatment‚ a higher carbon content reduces weldability. In carbon steels

Finding the percentage of copper in brass alloy. Introduction This is an investigation to find out how much copper is in a brass alloy. The brass alloy we are experimenting on is called Muntz Metal. Muntz metal is 60% copper‚ 40% zinc and a hint of copper [http://en.wikipedia.org/wiki/Muntz_metal] (accessed 4/10/12). Muntz metal was developed as an alternative to expensive‚ heavy copper. It is comprised of about 60% copper and about 40% zinc‚ with a small amount of iron. The finished product actually

magnetic field and the second finger shows the direction of the current in the wire. Construction: A coil of thin wire is mounted on an aluminum frame (spindle) positioned between the poles of a U shaped permanent magnet which is made up of magnetic alloys like alnico. The coil is pivoted on the jewelled bearing and thus the coil is free to rotate. The current is fed to the coil through spiral springs which are two in numbers. The coil which carries a current‚ which is to be measured‚ moves in a strong
