Saudi Arabian Mining Company (Maaden) (Riyadh, Saudi Arabia) and Saudi Aramco (Dhahran, Saudi Arabia) have announced the signing of a shareholders’ agreement to form a joint venture (JV) to unlock new opportunities in mineral exploration and hard-rock mining in the Kingdom of Saudi Arabia. Combining the strengths of two leaders in their respective fields, the […] The post Maaden and Aramco form J…

Aluminum scraps left over from factories and old products could be given a valuable second life as an extremely lightweight material used in cars, buildings and machinery. Researchers at Fraunhofer IWU in Germany are developing new ways to make aluminum foam using recycled aluminum instead of relying mainly on newly manufactured aluminum powder. Their work […] The post Scientists Turn Aluminum Sc…

The melting point is one of the most consulted properties in the choice of a material, but also one of the most misunderstood. It's often confused with the maximum operating temperature or with softening. Furthermore, different parameters are sometimes compared, such as the melting point of metals and the HDT of polymers, as if they were equivalent. Understanding this quantity helps to choose the…

Aluminum is a key material for sustainable mobility and resource-efficient products, yet its production requires substantial amounts of energy. Researchers at the Fraunhofer Institute for Machine Tools and Forming Technology IWU have now demonstrated how production scrap, aluminum chips, and end-of-...

“When you’re faced with a critical material problem, you can do one of two things: You can find more, or you can use less,” says Tom Lograsso, director of the Critical Materials Institute, a mineral research laboratory within the U.S. Department of Energy. The sheer quantity of rare earths required for magnet production is staggering […]

Nature Communications, Published online: 13 August 2026; doi:10.1038/s41467-026-76700-3 In-situ entropy modulation during the laser powder bed fusion process is used to fabricate a near-defect-free alloy (relative density >99.99%) which exhibits exceptional fatigue crack growth resistance and corrosion performance.

Scientists have created an unusually corrosion-resistant stainless steel that could replace costly titanium components used to produce green hydrogen. The breakthrough could reduce structural material costs by roughly 40 times and make seawater-based hydrogen production far more economical.

Bronze Age rings from Greece hid an astonishing secret in their metal, one that may trace elite craftsmanship to material that fell from space.

Every watering setup in the yard faces the same material stresses that engineers evaluate in building products: corrosion, UV exposure, repeated flexing, and puncture risk. A stainless steel garden hose answers those stresses with a braided metal jacket wrapped around an inner water tube, and the design has moved from niche catalog item to a […] The post Stainless Steel Garden Hoses: Materials, D…

Scientists have found a way to improve the performance of 3D-printed aluminum bronze, a metal that could be useful for cooling powerful electronic components in rockets, aircraft and electric vehicles. Researchers from Skoltech and State Marine Technical University studied how different heat treatments affect aluminum bronze made using 3D printing. They discovered that heating the […] The post A …

The results provide a foundation for further development, but several challenges remain. The researchers want to reduce cracking, improve durability, and determine how to manufacture more complicated shapes. “The approach of forming metal materials by softening them rather than fully melting them is novel, and it has the potential to be applied not only to […]

What is steel made of? The short answer is: iron and carbon . The complete one opens up a whole world. Steel is a metal alloy composed of over 95% iron, but it's the remaining elements that determine its characteristics. Understanding the composition of steel means understanding why an S355 behaves differently from a 42CrMo4, why an AISI 304 resists corrosion while a C40 doesn't, and how to inter…

One of the biggest challenges in the U.S. critical minerals supply chain is in recovering valuable materials not only from traditional sources but also from resources that have already been mined. Colorado School of Mines metallurgists are leading the way with creative new recovery and recycling methods, developing innovations in retrieving metals from end-of-life batteries, secondary resources l…

A microscopic grain preserved an atomic structure created inside Hiroshima’s fireball.

A strange new object, never seen before on Earth, has been discovered at the site of the Hiroshima atom bomb blast. The previously-unknown metal was found at the place where the "Little Boy" bomb hit, killing more than 50,000 people. Scientists analysed tiny grains within the debris, finding the alloy inside a glassy particle known as "hiroshimaite", recovered from beach sands in Hiroshima Bay. T…
