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...

Continuing recovery in European markets more than offset volatility in exports of alufoil products, according to figures just released by the European Aluminium Foil Association (EAFA). Deliveries of all gauges rose 0.5% year on year, in the three months to September 2017, with domestic deliveries ahead by 1.4% compared with last year. Exports performance continues to be weak, falling 2.8% in that period. In the first nine months, total deliveries improved 0.9% to reach 671,000 tonnes (2016: 664,700t) +0.9%, maintaining the positive performance seen in the first two quarters. Thinner gauges, used mainly for flexible packaging and household foils, rose by 1.4%, while thicker foils, used typically for semi-rigid containers and technical applications, were just 0.1% better – but...

The Pahang government still faces various problems relating to bauxite mining, despite the federal government having imposed a moratorium on the activity, Menteri Besar Adnan Yaakob told the State Assembly. Adnan said the problems included failure of bauxite mining operators to comply with the time for them to carry out their activities within the stipulated period, from 8am to noon and from 2pm to 4pm. "There are also stockpile operators who mine and transport bauxite even though they are issued the approval permits (APs) by the Natural Resources and Environment Ministry. "There are also more special AP issued than the quantity of bauxite available," he said in reply to Fong Koong Fuee (BN-Cheka) who wanted to know the status of unresolved issues on bauxite mining since the moratorium...

For the renovation of contemporary art gallery SITE Santa Fe, New York-based SHoP Architects has added a pair of pointed courtyards wrapped with diamond-patterned perforated aluminium. SHoP Architects renovated and extended SITE Sante Fe's former beer warehouse building to create extra gallery spaces, a new public entrance, and indoor and outdoor spaces for its growing audience. Two extensions are set each end of the building in the New Mexico capital. The aluminium cladding these volumes is intended to complement the railyard facing the gallery on the city's Paseo de Peralta. "The folded, perforated-aluminum facade system was carefully calibrated to be appropriate both for SITE’s immediate context in an old railyard, as well as in contrast to the traditional construction methods and...
The bauxite industry is likely to see improvements in its performance with the increase in world demand for aluminum, and the construction of a new mine in 2018. The construction of a mine at Bonasika next year is anticipated to benefit the industry with added productive capacity, Minister of Finance Winston Jordan noted. Approximately US$50 million is expected to be sunk into this project, which is expected to employ more than 150 workers. Production is scheduled to begin in 2019 with some 300-400 individuals from Matthews Ridge and surrounding communities benefiting from employment. Guyana’s Minister of Finance Winston Jordan outlined the performance and projections for the mining sector, during his presentation of the 2018 National Budget, to the National Assembly.
