The integrity of an extrusion is much more consistent than that of a casting. Castings are inherently more porous due to their manufacturing process, and this results in more material used for structural applications. In result, the aluminum extrusion is inexpensive(dies) and take shorter time than casting manner. ?@

Since the RF signal travels with a "skin effect" on the top of the inner conductor, the outer conductor only serves as a shield that holds the signal in the pipe. In actuality aluminum is a better choice over copper as an outer conductor for the following reasons: which protects from further corrosion whereas copper will continue to corrode creating pock marks that See similar questions...

In our opinion, there are no advantages. Heat transfer or conduction is not improved. Oxygen diffusion benefits are usually irrelevant and if an oxygen diffusion barrier is needed, another method should be selected. Freezing conditions can rupture the aluminum portion of the tubing.

Aluminum is lighter and less costly per pound than copper. However, the disadvantages include electrochemical decomposition, lower fatigue strength, and the buildup of a hard sapphire oxide coating. In addition, resistivity is higher at 16.782 ohms/cmf compared with 10.371 for copper. At this time beryllium is not on the list of materials restricted by the European Union.

Active R&D has been undertaken by private companies, universities, and National Laboratories to advance all aspects of aluminum extrusion technology. A comprehensive collection of past work can be found in the Proceedings from the International Aluminum Extrusion Technology Seminars, known as "ET" for short. These are available from the Aluminum Extruders Council via their Publications list. See similar questions...

The tools required for aluminum extrusion - dies and related elements - are relatively inexpensive compared with those necessary for other production methods. Initial investment may be quickly amortized and even a fairly small production run may pass the "bread even" point, thus economically justifying the use of extrusion. See similar questions...

There are three main advantages of using Metastorage over traditional development methods that are less automated: Metastorage is capable of generating code from your component model definition in just a few seconds. It would take days or weeks to write, test and debug equivalent code manually by a human developer. This is very important to reduce the time to market your software products, especially if they are medium or large size projects. See similar questions...

There are two common methods of vinyl fence manufacturing: mono-extrusion (single layer) and co-extrusion (two-layer). Some manufacturers maintain and advertise that mono-extrusion is better. Which is better for you? In mono-extrusion, the fence profile (in sizes such as 2" x 6", 5" x 5", etc.) is made out of one layer of material. This process puts ultraviolet inhibitors (which protect the vinyl from sunlight) all the way through the product, even on the inside, where they are not needed. See similar questions...

Aluminum grilles are most often used in wall or ceiling applications because they are lighter in weight. Aluminum grilles are also rustproof and therefore perform better in moist locations. Also due to their lighter gray color, Aluminum grilles are easier to paint to match the surrounding environment. See similar questions...

Two reasons: Holes and fasteners. With conventional aluminum construction, there are literally thousands of holes. Each hole must be located, drilled, deburred, dimpled or countersunk. And then the hole must be filled with a rivet. Every single operation on every single hole takes some amount of time, and all of that time adds up. With composite technologies, we can make the kit parts and assembly process much simpler and more time-effective. See similar questions...

The obvious advantage of our system is the cost. An average DURAFORM® set usually costs less than half of the price of an aluminum set. Accessories are also significantly less. The DURAFORM® System is also easier to set windows and vents. With the DURAFORM System, you need only one grade of form release agent over the entire life-span of the form. With aluminum, various grades are required over the life span of the forms. See similar questions...

Clean. Geothermal power plants, like wind and solar power plants, do not have to burn fuels to manufacture steam to turn the turbines. Generating electricity with geothermal energy helps to conserve nonrenewable fossil fuels, and by decreasing the use of these fuels, we reduce emissions that harm our atmosphere. There is no smoky air around geothermal power plants -- in fact some are built in the middle of farm crops and forests, and share land with cattle and local wildlife. See similar questions...

Gasketed-joint PVC provides many advantages over other types of joining systems. The following is a brief summary: Watertight Joints: Gasketed-joint PVC water and sewer pipe joints are virtually leak-free, enabling them to easily pass post-installation air tests or leakage tests. Installation Considerations: Ease in installation is another advantage gasketed-joint PVC offers. See similar questions...

Unlike other retaining wall products. Keystone's pinned system offers the choice of near vertical or one inch setback options. It allows you to achieve tight comers and radii automatically without having to cut units while maintaining the running bond pattern. The Keystone fiberglass pins also provide additional shear strength at the wall face and positive connection with geogrid which allows proper pre-tensioning and resistance to bulging during construction.

In certain patients, stents reduce the renarrowing that occurs after balloon angioplasty or other procedures that use catheters. Stents also help restore normal blood flow and keep an artery open if it's been torn or injured by the balloon catheter. See similar questions...

Natural and propane gas continue to be the best value for your energy dollar. Compared to electricity, natural or propane gas appliances can cost less than half as much to operate. As a gas customer you'll enjoy savings up to almost 50% on your heating, water heating, clothes drying and cooking costs! More importantly gas is a safe, reliable, and environmentally-friendly energy source. Back to Top See similar questions...

Having different BISLs tailored to each programming language allows each BISL to specify all the details of a program module's interface (how to call it) and behavior (what it does). If one has a generic interface specification language, such as VDM-SL [Jones90] [ISO-VDM96] [Fitzgerald-Larsen98], then one cannot specify all interface details. The division into two tiers allows the language used for each tier to be more carefully designed and expressive. See similar questions...
