One of titanium’s pluses is low thermal expansion. In fact, you need a fraction of the amount of titanium to get the same physical strength you would get with aluminum. (I’ve never owned one, but I heard the aluminum sport models offer the strongest haptics.) In terms of appearance, titanium’s color varies depending on how much it has been altered. A simple comparison of the chemical and mechanical properties of these metals will show how they differ and what might be better for a given ta… If you need titanium parts, one advantage you might not have thought of has to do with titanium’s cost. In a head-to-head comparison, if you need something with impressive strength that can tolerate a high friction environment, 7075 makes the most sense. Stainless steel can be broken if you drop it from a certain height. It’s often used for casting and is most similar to a 3000 series alloy, given the addition of magnesium as the principal alloying element. The Apple Watch is available in aluminum and stainless steel (as well as titanium). Using powder means you end up with virtually no waste metal. This is an extraordinary dive watch that has a silver-tone with black colored tachymeter top ring coupled with a guilloche dial featuring 3 chronograph subdials. However, because of the price, it is still often compared to aluminum, which is also a very strong metal but offers a lower price point. Aluminum and titanium are both light, but for different reasons. Titanium is also one of the most common metals on Earth, but its melting point is so high it’s difficult to process it into a usable product. Sign up to get manufacturing news and updates! But aluminum, titanium watches are tough to get rid of the scratch. Is the quality of the metal different enough to warrant the price increase?

Using a fusing laser to weld powdered metal together, it forms parts, layer by layer. Titanium vs. Steel and Aluminum Did you know … About 50% of the cost of Titanium product is related to machining? Scratches are more noticeable. It has a very high strength-to-weight ratio, weighs about half as much as copper and only slightly more than half of stainless steel. And added bonus? It can range from dull gray in raw form to shiny silver when smooth. Strength/Weight: In critical situations where every gram counts but you need strong parts, titanium is the way to go. Titanium is known for its strength and has a high strength-to-weight ratio. Titanium is a strong, lightweight material that is used in many different applications. DMLS is an additive manufacturing process. Titanium parts have additional cost implications because they are difficult to machine. Aluminum machining is popular in the auto industry where lightweighting is key to improve fuel economy and minimize impact on performance, such as this tensioner for Litens Automotive. Apple Watch Series 3 and Apple Watch SE are available in aluminum. Aluminum’s low specific gravity (2.7 g/cm3) means that it’s considerably lighter than counterparts such as steel, which is about three times as heavy. It also offers excellent corrosion resistance and equally poor electrical conductor. Moreover, while manufacturing costs are somewhat higher using DMLS, the parts deliver value through the combination of strength and weight reduction. Proto Labs, Inc., 5540 Pioneer Creek Dr. The processes are fast—often producing parts in less than a day—and they adhere to tolerances of +/- 0.005 in. Grade 5, or Ti 6Al-4V, is titanium alloyed with 6% aluminum and 4% vanadium. The aluminum alloy used in the DMLS process adds silicon and magnesium, building parts with material properties exceeding their die-cast counterparts. Titanium vs. Aluminum vs. That’s a big reason why it is more expensive than other metals. The EcoDrive titanium watch by Citizen is one of the best titanium watches and is a top contender in this titanium vs. stainless steel watch comparison. One factor you might not think about when choosing material is machining waste. Apple Watch Series 6, Apple Watch SE, and Apple Watch Series 3 have a water resistance rating of 50 meters under ISO standard 22810:2010. While aluminum generally doesn’t react to acids, it does tend to corrode in alkaline (basic) environments. When comparing titanium and stainless steel Apple Watch Series 5 models, expect around a 5-gram difference in weight. Titanium is light, scratch-resistant, corrosion-resistant, durable, and hypoallergenic, but still, at present, more expensive to machine than stainless steel or aluminum. The aluminum alloy used in our direct metal laser sintering (DMLS) process, AlSi10Mg, adds silicon and magnesium. The properties of 3D-printed aluminum exceed its die-cast counterpart except for lower elongation at break. Carbon Road Bikes. There are many elements can impact the final choice for an application, though, and both the cost and the metals characteristics need to be considered. Most of these elements are natural, that is, they occur naturally whereas the rest are synthetic; that is, they do not occur naturally and are artificially made. Perhaps the best smartwatch in the world, Apple Watch Series 6 comes in two sizes; 44mm and 40mm, both of which are available in Cellular and GPS only models. Especially as notebooks get thinner and thinner, I would think they'd pursue stronger and stronger materials, rather than the other way around. The new Apple Watch case has special characteristics to help it wear better over time: Only found in the most exclusive watches, titanium is exceptionally strong, lightweight, and beautiful. Aluminum vs titanium In the world we live in, there are numerous chemical elements that are responsible for the composition of all the non-living things around us. The titanium color on the Apple Watch Series 6, available only for the titanium case variant, looks clean, simple, and at the same time offers a natural look and beautiful brushed finish. Over the years I have had stainless steel and titanium Apple Watches, and I found that the titanium model offered stronger haptics than the stainless steel. Titanium is used in aircraft jet engines, for example, and in spacecraft, too. More specifically, 6061 is the choice for bicycle frames, SCUBA tanks, fishing reels, small boats, and vehicle frames.

Citizen was the first watch company to fashion a watch out of titanium in 1970, and several brands have since taken it upon themselves to machine titanium watches. Because both materials offer high strength and low weight, it’s important to look at other differentiators when deciding which alloy to use for your parts. Titanium and stainless steel watches aren’t the only options. We’ll leave the titanium option for now and focus on the more obvious riddle here - aluminum versus stainless steel. Moreover, rather than absorb heat, titanium likes to reflect it, so you’ll find it in low-E windows, bouncing back warming infrared rays from the sun. Which is stronger? Because of this, engineers often choose to manufacture prototypes using aluminum, then switch to titanium for production parts. Titanium Apple Watch (top) with the aluminum (center) and stainless steel (bottom) In comparison, the basic stainless steel version costs $699 or $749. For watches, the most common forms are Grade 2 and Grade 5 titanium. With a melting point of about 3,000 degrees F (1,660 degrees C), when exposed to heat, it maintains its form better. Wonder what the differences really are between the stainless steel and aluminum Apple Watches? Aluminum is everywhere—it’s the most common metal on the planet. Weighs more. While milling away excess material is fine for inexpensive aluminum, it’s not ideal for pricey titanium. Following titanium, aluminum comes next. We’ll leave the titanium option for now and focus on the more obvious riddle here – aluminum versus stainless steel. When you think of a dream team of material characteristics for parts, light weight and strength come to mind. This saves assembly time and reduces your Bill of Materials (BOM). Machining Titanium vs Steel; Machining Titanium vs Aluminum; Common Uses for Machining Titanium; Titanium is widely used in a variety of applications due to its versatility and strength. I know they made the change forever ago, but I've alsways wondered why. In general, aluminum finds its way into aircraft and building materials, such as non-load-bearing framing. And if you’re looking for a good electrical conductor, aluminum can do that. Apple Watch Series 4, Apple Watch Series 5, and Apple Watch Series 6 are available in both aluminum and stainless steel, which is made of stronger material. Although titanium is about two-thirds heavier than aluminum, its inherent strength means that you need less of it. The titanium, Apple Watch, on the other hand, has two colors, and starts at $500 less than the ceramic model. I… It will look good with most, if not all, of the available Apple Watch bands, while the titanium case is exceptionally durable and fingerprint-resistant. Because both materials offer high strength and low weight, it’s important to look at other differentiators when deciding which alloy to use for your parts. Its strength and light weight reduce fuel costs. Both materials tick off other important boxes, such as excellent resistance to corrosion and tolerance for heat. Bronze is another material that … The titanium used in our DMLS process is Ti 6Al4V, more commonly referred to as Ti 6-4. (0.13mm). Lightweight, strong materials like titanium and aluminum are popular in lots of industries, titanium parts is ideal to be used for reducing weight and decrease energy consumption. For example, the Apple Watch (Amazon) comes in either stainless steel, or aluminum, which tends to be a softer, and lighter material, similar to titanium. The Apple Watch 6 is available in three flavors - aluminum, stainless steel, and titanium (no ceramic option, sadly.) Titanium is about twice as strong as aluminum is is much more scratch resistant. The new titanium Apple Watch won’t be as light as aluminum … Machining just can’t match DMLS’s design flexibility, regardless of which metal. Titanium’s corrosion resistance and lack of reactivity makes it the most biocompatible metal, so it’s great in medical applications, such as surgical instrumentation. The big difference between your two choices for machining aluminum has to do with the amount of copper in the alloy. That being said, I can't decide if the titanium is worth paying the premium over aluminum. DMLS lets you combine separate parts of assemblies into a single, strong part. The Apple Watch 6 is available in three flavors – aluminum, stainless steel, and titanium (no ceramic option, sadly.) It has mechanical properties similar to Ti grade 23 annealed and has exceptional tensile strength. Even though the metal case is a small portion of the overall watch weight, I'd wager that Apple's spec sheets are incorrect.
