Getting a clean, smooth finish while removing material quickly is not always easy when machining high-strength aluminium alloys. A new study on AA7075-T6 aluminium alloy has explored this challenge, identifying two different sets of drilling conditions to improve surface quality and maximise machining productivity. The research examined how cutting speed, feed rate and drill depth influence conventional drilling performance. Using response surface methodology and a central composite design, the researchers developed predictive models to determine how changes in these parameters affect the machining process. The models showed a strong level of accuracy, with coefficients of determination (R²) reaching 0.9731 for surface roughness and 0.9359 for material removal rate. Further confirmation...
Cleaner aluminium depends on three things going right at once: scrap collection, melting it in a furnace without much carbon, and the electricity behind the whole chain not being coal-powered. Developments across North America, the UK, the European Union (EU), Egypt, Thailand, Malaysia and India depict how unevenly those pieces are falling into place. While some markets are losing recoverable metal at the sorting line, others are redirecting cargoes or writing scrap into industrial policy, and a few are lining up green projects to hold primary aluminium production together. Aluminium scrap trade: North America leads, Thailand bans, EU retains The international aluminium scrap market is facing a combination of changing trade flows and growing pressure to secure cleaner, more consistent...
