Specialized Aerospace Fasteners for Different Applications...

Aerospace fastener technology has been around since before the airplane, as aerospace fasteners were routinely used in dirigibles. As the technology developed to adapt to include commercial, business, military, and space-destined products, the aerospace fasteners evolved as well. The aerospace industry utilizes all sorts of fastener types: screws, rivets, bolts, pins, etc. The key difference amongst the various types is quality of components. Aerospace fasteners must be durable in order to withstand high pressure and high temperatures, and yet still be lightweight enough to enable the lift of planes and keeping down fuel costs for rockets. This is why there are various types of equipment and metal treatment methods involved in perfecting the aerospace fasteners. The first type of aerospace fastener is the aluminum kind. It’s a lightweight metal, so using it in atmosphere-based planes is very efficient. However, it does require extra care and treatment. Aluminum rivets and fasteners are common, but the aluminum itself must be cold-treated. Even still, the fastener will be sensitive to any temperature of 250 degrees Fahrenheit and over, and is subject to stress-induced corrosion. Steel aerospace fasteners are very strong, as steel is a hard and sturdy alloy. Unfortunately, the material also makes them very heavy, which can cause problems for aircraft and spacecraft. Only the proper series of stainless steel can be used, as the steel fasteners are subjected to high heat and corrosion. Series C300 is corrosion resistant, though not as heat resistant. It’s used for aerospace fastener covers. Series 400 is also corrosion resistant and is more heat resistant, but it is prone to rusting. An experienced distributor and/or manufacturer will have a working knowledge of aerospace fasteners and, as such, will know which type of steel is best for the specific type of...

Backward inclined fan impellers...

With a centrifugal fan design the air enters the impeller along the impeller axis; the air is then discharged at right angles to the impeller. Backward inclined fans are capable of producing high pressure and high air flow. The impeller is located in a scroll shaped housing that directs the air flow, efficiently converting kinetic energy to static pressure. These types of fans can be single or double inlet meaning the air can enter the scroll from either one side or both sides. The impeller of a centrifugal fan can be a number of different shapes; the main types are forward inclined and backward inclined fans. It is the blade shape that determines the performance and efficiency. Although the shape is a principal factor in fan design, the width of the impeller and the clearances between the outside of the impeller and the inside of the casing and the discharge area also has a significant effect on the performance of the fan. With the advent of electronic speed control for motors many of these fans are now direct drive where in the not too distant past the drive was a belt and pulley arrangement. The new drives increase the efficiency anywhere from two to 10 percent, lessen vibration and reduce maintenance. Backward inclined fans are characterized by the blades; they tilt away from the fans rotational direction. Depending on the design of the blade these fans can reach efficiencies of 90 percent. The air leaves the blade tips at relatively low speed or velocity, this means that the fan runs quiet and have low friction losses. Narrow impellers rarely use an airfoil shaped blade as there is little increase in efficiency but when the design dictates a wide impeller, airfoil shaped blades are very...

Impact and push extrusion...

Aluminum is a soft material, when a shape is desired it can be accomplished either by pushing a billet of heated aluminum through a die which has an opening the same shape as the desired finished extrusion or a slug of aluminum can be cold forged which requires no pre-heating. Both of these processes are done by aluminum extrusion companies which have the equipment and skilled operators to perform the work. Extruded aluminum parts or shapes are used in a number of different industries from furniture manufacturing to the production of aluminum cookware. Although the shapes are different, aluminum is the ideal material as it is lightweight, durable and not prone to corrosion as is ferrous metals such as steel. Heat is a necessary component of push extruding as the billet which is usually round and of considerable diameter must be pushed through the opening in a die. If the billet was not heated close to melting it would not pass through the die. Aluminum extrusion companies that perform cold forming are not faced with the need for heat, the process they use takes aluminum slugs, and using a punch and die, the slug is formed using pressure only. The first step in the cold forming process is to coat aluminum slugs with a lubricating material after which they are set in the die. Once the component has been formed, it is either ready for use or it may need trimming before final finishing. During impact the stresses can cause small cracks in the material and it is the task of the designers to ensure that molds and pressures are matched to avoid this. There are two types of impact extrusion; forward and backward. In forward extrusion the metal is forced into a mold,...

Choosing a Supplier for your flat or round aluminum bar stock...

Depending on your specific needs and requirements for your aluminum round stock, you should locate a local service that can offer you the best type of stock to solve your requirement issues. Most people haven’t heard of aluminum bars and this is likely to be because they have never come across the need for them or do not know to which applications they are appropriate. Bar stock is typically milled, extruded, drilled, sawed or turned, depending on the type of material used to make it. In the case of some bar stock, the material would be wood, but in most situations the material required would be metal—usually aluminum or steel or an alloy. The Best Way to Choose a Supplier for your Stock Firstly, when choosing a supplier for any kind of service, material or item you should initially research the history of the company and see how many testimonies or recommendations they have from their current or previous clients. Find out their policy for delivery, payment, lines of credit, set-up time, equipment and other items needed to make the project go smoothly. Also, you can do yourself a huge favor and research the product that you will need. If you need, for example, an ‘Acc-u-bar’ round stock you might want to check them out and you will find out whether it is the cheapest, best, most expensive, better quality, item or not. Read reviews, but do be careful exactly what you believe about them. Many people are paid to write reviews these days so make sure that you get genuine reviews that give you the clear picture. Speak to the manager or owner of the business that provides the round stock that you need and ask any questions that you feel are important....

About Types of Aluminum You can Purchase From Suppliers in Cincinnati...

Aluminum is a metal material that is high in demand for various types of projects. There are several different types of aluminum that can be purchased and used for a variety of reasons.
