In this work microfabricated three-dimensional polymeric nanolattices were conformably coated with a thin layer of high-entropy alloy (CoCrFeNiAl0.3) film via physical vapor deposition.

Periodic three-dimensional (3D) structures with nanoscale constituents, often referred to as ‘‘nanolattices’’, are of extensive interest recently due to the rapid advances in additive manufacturing (such as 3D printing) at the micro/nano-scale. They have great potentials to be used for a variety of engineering applications, such as light-weight structural materials, functional frameworks for sustainable energy, scaffolds for cells culturing and drug delivery, etc. High-entropy alloy (HEA), on the other hand, is a new kind of alloy constructed with equal or nearly equal quantities of five or more metals, showing unprecedented properties owing to their unique alloy designRead more

These are seamless copper tubes that Nu-Tech extruded, then the plug end and the flange end are electron beam welded on each end of the tube. The tube is part of a set of matching tubes (usually in groups of 12 or 14) that are put vertically, side by side, into a glass coating machine. Sheets of glass pass by these tubes and they rotate at a very fast pace and in conjunction with magnetization, fine particles of the copper “sputter” off to coat the sheets of glass as they pass through the machine. These large sheets of glass are used in Smart TVs, smart phones, touch screens, etc.

The unique welding capabilities of Nu-Tech Precision Metals have helped to garner the shop an Ontario Export Award

In an era of fierce domestic and international competition, Nu-Tech Precision Metals of Arnprior, Ont., has built its success on providing what few others can.

The Pentagon has identified cobalt and copper as “strategic and critical minerals” for the production of military planes, missile guidance systems, and other hardware. According to the U.S. Department of Defense, cobalt is a critical material because it used as a superalloy in military and commercial jet engines, and it is very difficult to substitute because of its very high heat resistance. As of 2014, 16 percent of the world’s cobalt was used in superalloys, five percent was used in magnets, and 42 percent was used in batteries, all of which are essential in military hardware as well as in hybrid and electric cars, commercial planes, and consumer electronics.

Japan’s Asahi Shimbun is reporting that Pyongyang’s recent string of successful missile launches is largely due to a Chinese firm that smuggled crucial tungsten and aluminum alloys to a North Korean company in April. The Japanese newspaper quotes a “source with deep insights into trade between North Korea and China” as saying that a Chinese private-sector company smuggled the materials, including high-grade tungsten and aluminum alloy, to North Korea’s central science, technology and trade company.

According to a source with deep insights into trade between North Korea and China, a Chinese private-sector company smuggled materials needed to develop missiles to North Korea sometime in April. In particular, high-grade tungsten and aluminum alloy was sent by the Chinese company to North Korea’s central science, technology and trade company. It was not clear what volume of materials was sent or the course used to smuggle them.

The tungsten was coveted by North Korean rocket scientists due to its hardness and penetrating ability. They also needed high-grade aluminum alloys to make their missiles stronger and lighter. Asahi says the unnamed ChineseRead more
