Applying heat to metals can make them easier to forge, machine, weld, and fabricate. However, this also brings some issues with it, metals expand when heated, which makes the whole fabrication process more demanding. Luckily, every alloy comes with a predetermined coefficient of thermal expansion. This coefficient shows how much a given alloy will expand […]
Read MoreWe often mention that said metal is “easy to machine” or “difficult to machine” on our alloy pages, but what is machinability really? To answer that question, we need to first talk about machining and why it’s essential in almost every industry that uses alloys. Machining is the process of removal of raw material, in […]
Read MoreAt Tech Steel and Materials, we are serious about the products we produce, from start to finish. One of our specialties is to supply steel, more specific, steel billets and bars. What is a steel billet? Steel billets are the product of melting iron ore or scrap iron using a method first introduced in the […]
Read MoreElectric planes flying on batteries are no longer a midsummer night’s dream, as an Israeli startup named “Eviation” is planning to introduce the first one by 2021 which will carry nine passengers over distances of up to 650 miles (1045 km). The key technological development that makes this possible is the existence of high-density dry […]
Read MoreDelivering packages with the help of drones is certainly not a novelty, but it is still not spread enough to replace conventional methods. Amazon wants to change that with their new hexagonal drone, which was presented at their re:MARS Conference. This drone should improve the Primer Air delivery program, which is available in selected countries […]
Read MoreIs there anything that is still secret in our digital world today? How secure is your everyday movements, day to day routines and most intimate information? Are we really protected by firewalls and passwords to secure our most precious information? Have we become so gullible to accept the big banners on software promotions promising just […]
Read MoreThe Dragon II capsule that carried out a non-piloted test flight to the ISS in March has exploded during a later test on the ground, as confirmed by the SpaceX vice president, Hans Koenigsmann. The explosive event was already apparent from a video that leaked late last month, but the level of the vessel’s destruction […]
Read MoreModern aircraft rely on complex moveable flight control surfaces to maneuver their path through the air. BAE Systems revolutionize the future aircraft design First time in history, a flapless unmanned aircraft has been maneuvered in flight by replacing moving surfaces with the blown air technology. UK‘s largest defense and security company BAE Systems has performed flight […]
Read MoreIn a settlement agreement, an Oregon aluminum extrusion manufacturer, Sapa Profiles, Inc., has agreed to pay $46 million to NASA, the Department of Defense, and others to resolve criminal charges and civil claims relating to a 19-year fraud scheme. Federal prosecutors concluded that Hydro Extrusion Portland, Inc., formerly known as Sapa Profiles Inc. (SPI), and […]
Read MoreTechnology has come a long way since the first application of the wooden wheel in 4500–3300 BCE i.e. the Neolithic Age. Since the first patented pneumatic tire by Scottish inventor Robert William Thomson in 1847, we’ve had everything else in between up until the 21st Century, which included white wall, radial, low profile, off-road, snow, all […]
Read MoreMedical samples are vital elements in many hospitals. Their transport, however, gets complicated when the amount of blood or tissue samples increases. UPS recently decided to tackle this problem. The company started to move medical specimens with unmanned drones. So, the futuristic idea about drone deliveries for various industries just got real. Their drone-delivery scheme […]
Read MoreSeveral decades ago, it seemed almost sure that in the year 2020 we would’ve lived in cities with flying cars. Sadly, the reality is that we are not as close to this truth as futurists predicted. That said, we can almost certainly predict that flying cars will happen in the near future. Boeing’s subsidiary Aurora […]
Read MoreEveryone agrees that electric propulsion is the future in mobility, both in the automotive and aerospace sector, but there are still mountains to climb before it becomes the de facto standard. It will be especially hard to make an electric airplane for passengers and cargo that can fly over long distances because batteries are very […]
Read MoreAirplanes today are one of the most well-engineered things, and they need to be if we want them to be safe. That said, they have too many moving parts, like turbine blades and propellers, that only add to the complexity and therefore, make them less reliable. Thankfully, there is a new advancement in this field […]
Read MoreJimmy Toton, a Ph.D. candidate at the RMIT University in Melbourne, has won this year’s “Young Defence Innovator Award” along with the $15000 money prize that accompanies it. The young engineer has presented a novel 3-D printed steel cutting tool that convinced the judges of its performance by cutting through titanium alloys in a manner […]
Read MoreElectric airplanes really sound exotic and forward-thinking, but we’re far from a commercial airplane with this kind of propulsion. The problem is batteries – they are very, very heavy for an airplane. That’s why focusing on improving the existing technologies for the reduction of the carbon footprint of airplanes has become even more important in […]
Read MoreThe U.K. is investing $2.65 billion to become the first nation in the world to have a fleet of hi-tech unmanned fighter jets. A full-size model of the U.K.’s proposed next-generation jet fighter, called “Tempest,” was unveiled at the Farnborough International Airshow, held at the Farnborough Airport in Hampshire, U.K., last month. If all goes well, […]
Read MoreThe Airbus Perlan 2 aircraft set a new gliding altitude world record recently. The pressurized glider flew to the edge of space to an altitude of an astonishing 76,000 ft. — well over 14 miles. The Perlan 2 glider is made of carbon fiber composite material. It is designed to soar up to 90,000 ft., has an […]
Read MoreScientists have long believed that water exits on the moon. But now, this belief has finally been confirmed by a team of scientists, led by Shuai Li of the University of Hawaii and Brown University, and including Richard Elphic from NASA’s Ames Research Center in California’s Silicon Valley. Definitive evidence of water ice on the moon […]
Read MoreA satellite orbiting 332 miles above Earth recently captured some neat footage of China’s OneSpace startup launching a rocket from the Gobi Desert. As cool as the video is, OneSpace was merely testing the solid-fueled booster of its OS-X1 rocket, reaching a suborbital altitude of 21.7 miles after taking off from the Jiuquan Satellite Launch Center.
