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...

Kobe Steel Ltd’s Japanese Industrial Standards (JIS) certification has been temporarily suspended at its aluminium extrusion plant in Chofu, western Japan, the company said in a statement on Tuesday, in the latest blow to the embattled steelmaker. Kobe Steel earlier had the certifications at its Hatano plant revoked for seamless copper pipe products used for air conditioning and refrigerators as well as for insulated copper tubing. Japan’s third-largest steelmaker, which supplies the manufacturers of cars, planes, trains and other industrial products across the world, has said that about 500 of its customers had received products with falsified specifications, in one of Japan’s biggest industrial scandals. The latest suspension would last until the aluminium plant improves its quality...

A consortium of the Societe Miniere de Boke (SMB) and Singapore’s Winning Shipping plans to build Guinea’s first alumina refinery in a $3 billion effort to develop the West African country’s bauxite industry, it said on Monday. Guinea has about a third of the world’s bauxite reserves and expects to produce over 30 million tonnes in 2017. However, it has no facilities to transform those reserves into higher-grade alumina, which can fetch higher prices on world markets. The project will include a 120 km (75 mile) railway connecting SMB’s bauxite mines in Boke to the refinery in Dapilon, which will process the raw material for export as alumina, mainly to China, SMB managing director Frederic Bouzigues told Reuters. Construction of the 1 million tonne per year refinery is due to start in...

The global mining and metals industry giant Rio Tinto Group has acknowledged China for boosting the use of aluminium cans in the carbonated beverage packaging sector. “In the packaging sector, especially around soft drinks and beer in China, we’re seeing a shift from glass to aluminum,” Rio Tinto Aluminium Chief Executive Officer Alf Barrios said in an interview recently. Aluminium demand will rise at a CAGR of 4 per cent over the next five years, and global consumption of refined metal- at 3-4 per cent per annum rate during 2018-2019, observed Barrios. With China implementing production cut policy, the price gains in the primary aluminium vertical will flow down the value chain thereby incentivizing Chinese packaging companies to add new capacity elsewhere. The shares of Chinese...
