The Hottest Metal in Town

The Hottest Metal in Town

The move toward lighter, renewable, and stronger metals has led many companies to turn away from the trusted steel to new metal- magnesium. Magnesium alloys have been around for quite some time and has always had a supporting role within the world’s most vital machines. Within the last ten years, as the price of gas, environmental awareness and consumer safety concerns have increased, so has the need for a drastic change in the design of many items to appease the masses. Government policy changes have added to the urgency. The result is the increased interest in magnesium alloys, which is the answer to current manufacturing needs.

Aviation

Losing weight on airplanes is important for the fuel economy. Actually, the usage of magnesium for airline construction isn’t new. It was used in airplane manufacturing through the 1950’s but was phased out because of concerns over flammability and corrosion. However, it is back today, in the form of a sheet. The return was made possible by improved magnesium alloy processing. The treatment used on the alloy’s surface also alleviated the corrosion concerns. The sheets are being used more and more in construction of aerospace vehicles to also create designs that are more aerodynamic, thanks to the lighter materials.

Automotive

Magnesium has been used in automotive engines for some time. As the need for more fuel-efficient cars rises, so does that search for ways to replace the heaviest parts of the car with lighter materials. A perfect case is the Ford 150 truck. For years, the truck was touted as made tough, of steel. The US government then enacted a law requiring all new light trucks to have fuel economy of 30 miles per hour by 2016. Combined with high gas prices and an increased demand for smart fuel-efficient cars, the law could have been the death knell for the once popular truck. Instead, the company began using magnesium alloys in the design of the Ford F150, starting in 2010, replacing much of the steel construction. The current frame of the truck is made completely of magnesium alloy.

Medicine

Magnesium is found within the body naturally, so using the metal alloy for implants and stents in medicine is advantageous. It limits the rejection rates, dissolves so the implants aren’t permanent, and are lightweight without sacrificing the strength needed in order support the body or blood flow.

Technology

Laptops are on the leading edge of magnesium use in construction. New slimmer, lighter laptops are more easily constructed using magnesium alloys than the traditional plastics and metals. Asus introduced an extra slim laptop, the U36, to rival one brought on the market by Apple in 2010. The durability of the alloy was another selling point for consumers.

Keep an eye out for magnesium alloy use in more and more products. The metal is plentiful, renewable, and rival to the aluminum and steel alloys in its strength to weight ratio. All of these quality factors translate to more durable eco-friendly products for consumers.…

The Science Behind 3D Printing

The Science Behind 3D Printing

3D printing is pretty interesting in my opinion; it’s going to lead to a change in the way that we do things in a wide variety of industries. First off, what is 3D printing? 3D printing is a fascinating form of manufacturing technology in which almost any shape can be created out of a wide variety of materials. These materials range anywhere from ABS plastic, ceramics, glass filled nylon, rubber like material, wax casts, stainless steel, Inconel, cobalt chrome, silver, platinum, and even gold. There are tons of materials to choose from! In fact, over 60 materials exist in the world of 3D printing. Anyways, let’s jump back to the actual process of 3D printing. For this process to work, a design has to be created before anything can happen. This design will be the blueprint for the actual product itself. Various softwares can be used to create these computer files. Just a few to think about would be 3DS Max, Maya, Blender, Autodesk products, and Tinkercad. There are definitely other softwares that work in this 3D printing process.

Regardless, a design will be created from one of various softwares. This design will then be sent to a technician, or the operator that runs the 3D printer itself. This design will be plugged into the computer of the 3D printer, and it will manufacture the product in accordance to the design. Keep in mind, the technician will also have to choose the correct machine, lay out the files, and start the printer. Other than that, the printing process is pretty automated.

When the process starts, dependent on the style of 3D printing, a layer by layer process will begin. The printer will begin laying down layers of material to create the design. These layers of material can sometimes be a fraction of the diameter of a human hair. As in less than 20 microns! That’s a fraction of a millimeter! The detail levels can go very high in a variety of situations. Back to the actual process. The machine will take into account the dimensions and schematics of the design previously created, and it will bring it into existence, one layer at a time. Various processes involve shooting ultraviolet lights at liquid resins, laser melting powder, adhesive sprays on powder, and FDM printing. FDM printing is probably the most popular. This process involves shooting strands of plastic through a heated extruder. Think of a hot glue gun shooting out glue, where the hot part is the extruder, and the glue consists of various materials. The 3D printer will use a computer aided manufacturing (CAM) system to create products. This means that the computer within the machine will tell the extruder exactly where to go, and where to melt material.

This process will continue layer by layer until a final product emerges. Dependent on the style, there are some post production requirements in which the technician will have to clean the model. Some styles of 3D printing call for the technician to dust off excess powder, dip the piece into strong bonding chemicals like epoxy, or add various finishes. Well, basically, that’s the 3D printing process!…

Recycle These Metals Immediately

A research found that only the top 2 to 3 % of active-fund managers had enough ability to cover their value. It’ll be so much cheaper than buying these separate, actively-managed funds — and, as the info have proven again and again — it’ll possible carry out better as properly. Amidst a vibrant house celebration, Downing explores the difficult minefield of teenage sexuality as John, the isolated native gay lad, finds a chance to precise revenge on his straight oppressor, the popular and handsome Daniel.

Coins could possibly be counterfeited, but additionally they created a brand new unit of account , which helped result in banking Archimedes’ precept supplied the following hyperlink: coins might now be easily tested for his or her advantageous weight of metal, and thus the worth of a coin could be determined, even if it had been shaved, debased or in any other case tampered with (see Numismatics ).

Have a look at look at how far behind the eight ball a lot of the state pension funds are. By 1900, most of the industrializing nations have been on some type of gold normal, with paper notes and silver coins constituting the circulating medium. But I do assume the dominance of the index fund will proceed just because we’re in an industry where value is every part and nobody needs to compete on cost.

Many options were prompt for this drawback, however most of these had been largely involved with the movement of small inexperienced items of paper, which was odd as a result of on the whole it wasn’t the small inexperienced items of paper that had been unhappy.

And I sincerely consider, with you, that banking establishments are extra harmful than standing armies; and that the principle of spending cash to be paid by posterity, beneath the identify of funding, is however swindling futurity on a big scale. Numerous plastic cards and different devices give individual consumers the facility to electronically transfer such money to and from their bank accounts, with out using currency.…
