Stainless steel is the more costly option, as well as the more flashy. All three colors have a pristine, glossy finish that is easy to catch the eye. These models weigh considerably more than the aluminum, easily appealing to those that like the fit and finish of traditional timepieces. Wit...
When you compare iron and steel with something likealuminum, you can see why it was so important historically. To refine aluminum, you need access to huge quantities of electricity. Furthermore, to shape aluminum, you have to either cast it or extrude it. Iron, however, is much easier to ...
Tool steel and aluminum staying strong: a roundtable of mold material suppliers discuss how new offerings result in easier machinability, better weldability, increased strength and improved surface hardness.(Mold Materials)(Discussion)Baranek, Sherry L...
Aluminum alloys play an important role in circular metallurgy due to their good recyclability and 95% energy gain when made from scrap. Their low density and high strength translate linearly to lower greenhouse gas emissions in transportation, and their excellent corrosion resistance enhances product lo...
Newer, high-performance hang-glider designs use a rigid wing with stiff aluminum struts inside the fabric to give it shape, eliminating the need for supporting cables. Hang gliding is often confused with paragliding, though the two sports are quite different from one another. Check out the ...
There will likely come a day when humans become so technologically advanced that iron is completely replaced by aluminum, plastics and things like carbon and glass fibers. But right now, the economic equation gives inexpensive iron and steel a huge advantage over these much more expensive ...
Aluminum Aluminum is a lightweight and highly durable material, conceived of from the start as a high-tech option. It is strong and pleasant to handle, being highly adept at matching ambient temperatures, and allows for a multitude of aesthetic options due to its ability to be painted any ra...
Artillery barrels are made of extremely strong hardened steel so that they can withstand the repeated blasts of artillery shells when they are fired. Inside this steel casing is nearly 650 pounds (295 kg) of tritonal explosive. Tritonal is a mixture of TNT (80 percent) and aluminum powder (...
Alnico magnets: These were developed in the 1930s and are made from aluminum, nickel and cobalt. They're stronger than ceramic magnets, but not as strong as the ones that incorporate a class of elements known as rare-earth metals. Neodymium magnets: These contain iron, boron and the rare-...
In the United States, the steel industry is expected to see steady growth for the rest of the decade. The economy is strong and growing. With that, the demand for steel will grow too as it is used in so many products and industries. While trade tensions with China and environmental conce...
