What is great about nickel (the metal)?
What is great about nickel (the metal)?A great feature of nickel is its high melting point, making it particularly suitable for use in the turbine of an aircraft engine. Nickel alloys are not easy to machine by conventional cutting tools on machine tools, so the creep-feed grinding process was developed to overcome this problem.In my early career, I worked on the development of some creep-feed grinding machines for machining turbine blades.Why are aircraft turbine blades made of nickel alloys?Creep-feed Grinding Is A Milling Process
What is Inconel 718?
Alloy 718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F. The sluggish age-hardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling. This alloy has excellent weldability when compared to the nickel-base superalloys hardened by aluminum and titanium. This alloy has been used for jet engine and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.Inconel 718 Round BarInconel 718 RodsInconel 718 WireInconel 718 SheetInconel 718 PlatesInconel 718 CoilInconel 718 FittingsTo know more or buy Inconel 718 Alloy visit :- www.sachinsteelcentre.in

What are the marine aluminum sheet alloys?
The marine aluminum sheet is mainly used for process ships, boat and yachts and they also developed rapidly. Due to the harmful substances generated during the construction and dismantling of FRP boats, aluminum boats have been developed.Marine aluminum alloys have been widely used in the world. Water yachts are also divided into many different types, and are generally divided into freshwater lake yachts and seawater yachts. Aluminum alloy manufacturing yachts can meet both of these needs and contribute to the lightweight of yachts.There are two types of aluminum alloy yachts, one is a small yacht, usually four or five people, and the other is a luxury yacht, which can take more than a dozen people.The marine aluminum sheet price is different with different alloy and application. In general, small yachts are generally in freshwater lakes and rivers, and generally do not travel at sea. The material of the freshwater lake small yacht is generally made of 5052H32 aluminum plate or 5052 O aluminum plate. Because it is fresh water, the corrosion is not as strong as sea water, so it is made of 5052 aluminum alloy. Marine yachts are almost all luxury yachts. Due to the corrosive nature of seawater, they are usually made of high-magnesium alloy of 5083 H116 or 5083 H321, and they have good corrosion resistance through special processing technology.

Which material allows sound to travel 4 times faster than in water?
It depends on the mode of propagation – longitudinal, transverse, or surface. Generally, it is preferred to work with longitudinal speed. Ultrasonic inspectors tend to induce transverse (shear) waves to bounce from surface to surface to access the conditions of an area of interest that can’t be accessed by direct probe contact.A feature can only be detected if the feature is perpendicular to the direction of travel as seen above. If there is something preventing probe contact, the above discontinuity cannot be seen.So if we induce a shear wave we can bounce the signal off of the far surface, then off of the discontinuity, back again off of the far surface and detect it at the probe.Sound travels at different velocities depending on the material and mode of propagation.We’ll stick with L waves for simplicity’s sake.Sound travels 1480 meters/second (or 0.0584 inches/microsecond) longitudinally in water under “ordinary” conditions – elevation, temperature, pressure (atmospheric, gravitational). So we’re looking for a material with a velocity of 5920 m/s (0.2336 inches/microsecond). Checking this, this, this, or this chart, we see that the closest candidates are iron, mild steel (and several alloys), quartz, magnesium alloys, monel, titanium, and vanadium.
What is the difference between silver and sterling silver?
Silver vs. Sterling SilverOften, sterling silver and silver are described as the same thing, but in reality, sterling silver is only an alloy of silver. Silver, which is usually called fine silver, consists of 99.9% pure silver. On the other hand, sterling silver consists of approximately 92.5% silver, and the remaining 7.5% (or even more) is of other metals. Because of the high percentage of silver in ‘pure silver,’ it cannot be used to make those daily rough and tuff items. Pure silver is just too soft if it is to be made or shaped into such items.Therefore, metal experts add other metals like copper, steel, or iron as substitutes for silver, but they will only serve to fill 7.5 to 8% of the entire metal so that the items made from the combination can stay in their shapes. When one adds other metals to silver to stabilize its shape, he or she is in the process of making sterling silver. The most common use of such is seen in making various utensils, like forks, knives, spoons, coffee sets and many others.Sterling silver easily loses its luster in many situations; but in the case of pure silver, it will remain non-responsive to tarnish on its surface. This is because tarnish is more responsive in alloy metals. To test the tarnish tendency of a metal or alloy, you simply have to rub your finger tightly over a shiny piece of your sample material. In sterling silvers, you usually find some dull smudges on your skin. Nevertheless, you can keep your sterling silver items shiny by using a cloth or cotton to regularly and gently clean its surface. Moreover, if you do not use your sterling silver items for a prolonged period of time, you may notice that tarnish starts to appear.You can buy sterling silver jewelry from here
Why is acetate plastic used in frames for glasses?
A short lesson in history. Frames of various plastics are known in the industry as “shell” frames. This is because the first frames of this nature were made out of tortoiseshell, which was a bit hard on the turtles.So, the search was on for a plastic material that was strong, could hold its shape, and could be coloured. Like a film for a camera or movie. The plastic used for early films was cellulose nitrate, and this was pressed into service for spectacle frames.Unfortunately, cellulose nitrate is flammable (another name for it is guncotton) and will self destruct and even auto ignite over years in storage. Thousands of feet of early film have been lost in this way. With spectacle frames, the main danger was in overheating when fitting lenses. The frames could disappear into a puff of smoke , leaving only the wires used in the temples (sides) of the frame.The film industry moved to cellulose acetate (they call it safety film) and so did the optical industry. Acetate can be made in multiple colours. Sheets are compressed together to make swirls and patterns. Some samples>In a factory, not so pretty.The frame shape is cut from the acetate.And then polished, traditionally in large drums.As Richard Hom said, then you end up with a frame that is easily made malleable with heat, for lens and face fitting, is colourful, durable and has low sensitivity.
