Aluminium in guitars – It's all music to our ears

Think of a guitar and the classic wooden version comes to mind. There are hundreds of types and they come in all shapes and sizes. Some passionate players even go for custom made guitars just to suit their movements and taste. The simple guitar is still evolving with newer uses of the instruments in concerts and other forms of music. The use of wood in the body and the neck of a guitar is not going to cease in a long time. However, the use of other selected materials by modern guitar manufacturers has significantly improved the sound quality and handling of the guitars. “Manufacturers were making custom guitars from solid billeted aluminum. I was still in graduate school and couldn’t afford such instruments. So I decided to make a competitively priced guitar. Instead of wood or plastic, I opted to use 0.080-in. aircraft-grade aluminum sheet metal because of its quality and durability,” says the then-future CEO of Normandy Guitars.

Aluminum Heat Sinks – The Invisible Saviors!

An aluminium heat sink It is commonly noticed that if you use your laptop or computer for longer hours or run applications which require a lot of graphics processing, the system starts lagging. Play video games long enough and chances are your computer will unexpectedly throw a tantrum. It might even trigger an unexpected shutdown. The reason why it happens like this is because the processors responsible for working inside your ‘closed’ device get hotter as the time passes. If the load is not decreased or the hot components don’t get cooled down soon enough, they may burn out and damage the device. Therefore, every electronic device, like some mechanical devices (cars), has a ‘heat sink’ where the immediate exchange of heat takes place to cool off these parts to increase their performance and longevity.   The cooling mechanism.

Talgo's lean Aluminium manufacturing powers super-fast and safe travel (2/2)

Hello! And welcome back to our blog post on TALGO trains. TALGO recently held speed trials in India for its 9 series unit. Let's continue from where we left off and talk about how achieving such high speeds is made possible by the Spanish manufacturer. Read our 1 st post on the Spanish TALGO trains here for more on this topic. TALGO trains boast of superior sustainability and safety features in the new age trains in addition to increasing the passenger comfort without compromising on the high speed proposition. The use of hi-tech sensors and microprocessors ensure that the train’s vibration are minimized by automatically adjusting the suspension system through a robust feedback system. The present trains running in India have been reported to be employing technology which is outdated by 3 decades. The amplified use of instrumentation and real-time feedback systems in the engine and the coaches are still to be incorporated in the present technological arsenal of t
