Built for cars, but ready for space: A warm welcome to AMAG CrossAlloy®57!

~ Matheus A. Tunes ~ Leave a comment

For decades, aluminium alloys forced a choice: the 5xxx family is easy to form but only moderately strong, while the 7xxx family is strong but difficult to process. The crossover concept, developed at Montanuniversität Leoben by the research group of Prof. Stefan Pogatscher, removes that trade-off. A tuned combination of magnesium, zinc and, in some … Continue reading Built for cars, but ready for space: A warm welcome to AMAG CrossAlloy®57!

Battery waste is worth billions!

~ Matheus A. Tunes ~ 1 Comment

As the world accelerates its transition to electric vehicles and renewable energy, the pressure to recycle lithium-ion batteries efficiently has never been greater. At the heart of most recycling processes sits a fine black powder called black mass — a mixture of cathode and anode materials, binder residues, and metallic fragments recovered from spent batteries. … Continue reading Battery waste is worth billions!

New recycling processes or new materials?

~ Matheus A. Tunes ~ Leave a comment

The sustainability debate in materials science sometimes asks the wrong questions. How do we recycle more aluminium & steel? These are legitimate — but they treat recyclability/sustainability as an afterthought, forcing materials never designed for circularity back into something useful at considerable cost and energy penalty: facts that Europe, specially, cannot anymore afford. The presence … Continue reading New recycling processes or new materials?

Unlocking processability of recycled crossover aluminium alloys

~ Matheus A. Tunes ~ Leave a comment

Aluminum crossover alloys are an emerging class of materials designed to deliver a broad and balanced combination of mechanical strength, corrosion resistance, and formability. By blending the characteristics of traditional alloy families - 5xxx and 7xxx series alloys - they open new possibilities for high-performance applications in transportation, energy, and structural components. This versatility also … Continue reading Unlocking processability of recycled crossover aluminium alloys

Coal power, definitively not an option!

~ Matheus A. Tunes ~ Leave a comment

Fine-particles containing sulfur oxide originating from coal power stations are related to a significant increase in mortality risks. This is a result of a comphreensive study just published at the Science magazine last month. I think it is now clear that we must act to stop further uses of coal as an energy source! HENNEMAN, … Continue reading Coal power, definitively not an option!
