Titanium additive manufacturing uses laser powder bed fusion (LPBF), electron beam melting (EBM), and directed energy deposition (DED) to build complex titanium components layer by layer from powder or wire feedstock. The technologies create unmachinable shapes according to their design specifications, yet the as-printed titanium parts require both hot isostatic pressing and heat treatment and […]

The machining and welding processes for titanium require completely different techniques, which do not apply to steel or aluminum production methods. The combination of titanium’s low thermal conductivity and its quick work hardening, and its high chemical reactivity at high temperatures requires shops to use slow cutting speeds and rigid equipment setups, and complete inert […]

Cobalt-based superalloys are engineered to execute beyond the molecular dynamics of nickel-based alloys at elevated temperatures through carbide and summation reinforcement. The attainment of such properties in these alloys as hot corrosion resistance, thermal fatigue resistance, and wear resistance can only be possible through solidification. Therefore, they should be chosen for stationary gas turbine vanes, […]

The primary regulation in relation to aerospace titanium plate is AMS 4911, which is a standard from SAE International specification of Ti-6Al-4V annealed sheet, strip and plate. This is the material that is specified in flight structures and not commercial metal structures, and the one that all procurement directors have to check before approving any […]

Custom titanium forgings provide structural components with aligned grain flow, delivering superior fatigue resistance and achieving 3:1 efficiency when compared to solid bar stock machining, which results in 8:1 or lower efficiency. The procurement directors and materials engineers require knowledge of the forging process, supplier qualification criteria, and RFQ requirements to manage expenses, production duration, […]

The aerospace program can achieve significant fuel cost reductions through material replacement decisions, but an offshore platform will face corrosion issues, which lead to early equipment failure. The Singapore procurement director needed to choose between titanium and stainless steel for the new desalination heat exchanger because the two materials presented different pricing options. Three years […]

The supplier datasheet needs to show more than “medical grade” because you require better documentation when you design or procure a titanium implant. The material must meet ASTM F67, F136, and F1295 standards, while the manufacturing process needs to follow ISO 13485 requirements, and every material component must be traceable to its certified heat number. […]

The alpha-beta alloy known as grade 5 titanium, which engineers understand best, serves as the most familiar titanium alloy for engineers. This material, which powers aircraft engines and supports surgical implants and resists seawater corrosion, lasts more than 100 years when used in place of steel. The titanium metal Grade 5 exists as a widely […]

The engineers who built the Curiosity Mars rover wheels faced a traditional materials engineering challenge when they created the wheel design. The team selected aluminum as their final material choice because titanium provides superior strength-to-weight ratio. The team selected aluminum because Martian conditions make titanium materials become brittle while aluminum materials permit thinner designs for […]
