In general, metals are shiny, reflecting most of the light that strikes them. They are malleable and ductile (that is, they will bend under pressure and are not brittle). They have a broad range of melting temperatures (e.g., mercury is a liquid at room temperature, gallium will melt ...
Besides seeing what effect a strong magnet has on different metals, try and find out the effect it has on different minerals. A great source of minerals is found in the shops of most public, natural and science museums and in science shops or nature stores at malls. They usually have a ...
Magnets will also attract some alloys, or mixed combinations of ferromagnetic metals with other elements, such as carbon and aluminum. The alloy alnico, for example, is a fairly strong and durable magnetic alloy consisting of aluminum, nickel and cobalt. Another alloy, which combines the rare-ear...
Palladium isthe most valuable of the four major precious metals, with an acute shortage driving prices to records in recent years. ... The metal is mined primarily in Russia and South Africa, and mostly extracted as a secondary product from operations that are focused on other metals, such ...
Explain the mechanism of electrical conduction in metals When an electric current is passed through two parallel conductors then due to mutual forces between them, do they move toward each other? If yes, what is the reason behind this? If bar magnets...
How do you tell brass from copper? To distinguish copper from brass, which is an alloy of other metals,examine the color under good white light. Real copper should have a reddish-brown hue, like a penny. Brass items tend to have a yellowish tint. If your item is yellow, orange-yellow...
You will either get metals from them or even work out a deal that allows you to sort and separate the scrap in return for splitting the proceeds. Brass (Yellow Copper?!?!) While brass is not as valuable as copper, you can find it in many useful or decorative areas. Brass generally...
Answer to: What is the behavior of timber, steel and reinforced concrete structural members in the presence of a load. By signing up, you'll get...
Although iron and other magnetizable metals can *hold* the form of the magnetic flow field, they are not the originators of it. All permanent magnets are “initiated” by a strong external magnetic field created by means of spin and electricity. Electricity is primary and the magnetic material...
Using Metals for 3D Printing Metal 3D printing, also known as Direct Metal Laser Sintering (DMLS) uses a laser beam to melt 20-60 micron layers of metal powder to make durable parts from metal powders. They mostly help to create tool components and finished parts for the aerospace and autom...
