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...

With speculations rife on dwindling aluminium and its raw material supplies from China, LME aluminium kept surging higher on Thursday, October 26, and closed at US$2,175 per tonne, up from its previous close at US$2,149.50 per tonne on Wednesday, October 25. The biasness towards and upside was so strong that even a stronger dollar could not weigh on it. To note, the U.S. Dollar Index DXY, +0.14 per cent which tracks the currency’s performance against six major currencies, was one per cent higher at 94.683, hitting its loftiest level since mid-July, MartketWatch reported. Price trend suggests that LME aluminium will continue to trade at highs in the near term. As on October 26, LME official cash buyer aluminium price (Bid Price) stands at US$2,174 per tonne, cash seller & settlement...
Kobe Steel Ltd said on Thursday 88 of its customers had yet to confirm its products were safe in the light of widespread tampering of specifications, but it has not received any requests for recalls. Twenty-six of these customers were overseas companies, Kobe Steel’s CEO Hiroya Kawasaki told a news conference. He did not name any of the companies. “The scope of the wrongdoing found is far beyond what I had imagined at the start of the probe,” he said. Japan’s third-largest steelmaker, which supplies manufacturers of cars, planes, trains and other products across the world, said earlier this month that about 500 of its customers received products in which specifications were falsified, one of the biggest industrial scandals in Japan. Kawasaki updated the total number of affected customers...
The city of Houston is resuming its curbside recycling program in November that was suspended more than two months. The city's Solid Waste Management Department announced the resumption will commence starting November 13. The recyclable materials include paper, cardboard, clean food cartons, plastic containers numbers one through five and seven, aluminium cans and bimetal cans. Glass will not be accepted in the curbside recycling program. The recycling service will begin from November 13 for “B Week” residents and November 20 for “A Week” residents. Houston suspended the recycling service program on August 30 due to Hurricane Harvey. Last month, Mayor Sylvester Turner announced that they would start picking up the green bins in the month of November, hopefully the first week.
According to a new study by Resource Recycling Systems (RRS) that was commissioned by the Can Manufacturers Institute (CMI), Beverage Can Makers Europe (BCME) and Abralatas in Brazil, aluminium beverage cans are the most recycled drinks package in the world.

The study established a global weighted average recycling rate for aluminium at 69%, PET at 43% and glass at 46%. The study verified and validated the data for 82% of the aluminium can global market (representing 21 countries), 79% of the PET bottle global market (representing 23 countries), and 79% of the glass bottle global market (representing 22 countries). As found by the study,...

Sujay Krishna Ranga Rao on Monday announced that the GOs on bauxite mining were cancelled, but chose not to speak on the GO No 97. K. Lokanadham said, “He should explain why the GO no. 97 on bauxite mining was not scrapped yet. The CAG had faulted the previous agreements reached on mining. Environmentalists are worried that bauxite mining would spell disaster to tribals and the entire north Andhra. Bauxite is poisonous and its mining would contaminate drinking water and causes health hazards.” The...
