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...

LME aluminium is trending high supported by a dipping dollar index, low inventory, strong demand, and positive Chinese economic data. The light metal closed higher at US$2,140 per tonne on Friday, October 13, rising from US$2,117.5 per tonne on Thursday, October 12. Shanghai Metals Market observes that the light metal contract will continue to move within the range of US$2,125-2,155 per tonne on Monday, October 16. Reuters’ technical analysis suggests that LME aluminium may retest a support at US$2,130 per tonne; a break above the level could cause a loss toward the next support level at US$2,117 per tonne in the near term. As on October 13, LME official cash buyer aluminium price (Bid Price) stands at US$2,139 per tonne, cash seller & settlement aluminium price (Offer price) is US$2,140...

The Trump administration seeks to include steel, aluminium and other basic materials under North American Free Trade Agreement (NAFTA) rules. The U.S. wishes to use NAFTA to boost these industries. The government wants to propose strict use of North American-made steel, aluminium, copper and plastic resins in the automotive sector. Sources said that the U.S. rules of origin proposal would put these materials in the NAFTA auto parts tracing list for the first time. The list is a reference to verify the regional content level of vehicles and parts in order to qualify for tariff-free shipment within all three NAFTA countries. U.S.negotiators has already submitted the proposal rules to Mexican and Canadian counterparts on Friday. Other sources added that the proposal includes raising the...

Kobe Steel parts used in Japan's iconic bullet trains failed industry standards, officials said on Thursday (Oct 12), bringing to light fresh evidence of wrongdoing by the steelmaker as investors speculated that the crisis could trigger a breakup of the 100-year-old company. Central Japan Railway, which operates the high-speed trains between Tokyo and Osaka, said two types of aluminium parts used to connect cars to wheels fell short in quality tests, though they do not pose any safety concerns. West Japan Railway, which runs services from Osaka to Fukuoka, also found sub-standard parts made by Kobe Steel, company spokesman Yudai Ochi told Bloomberg by phone. The latest scandal to hit Japan's storied manufacturing industry erupted on Sunday after the country's third-largest steel producer...

According to an SMM report, in order to make a harmonious and stable safety environment for the 19th National Congress of CPC, county government in China has ordered suspension of bauxite mining in North China County. Considering the fact that mining companies in Wangjiahou County are working with an oversized mining face and potential safety risk, the county government directed that from Sept.30th to Oct.31st, all mining companies in the country should suspend their production without exception. Any operation work has been strictly prohibited by order of the government till the time the event is over.

The government has plannned to introduce a deposit return scheme (DRS) for drinks bottles and aluminium cans in England. The report shows that the scheme would create savings for local government. Allison Ogden-Newton, chief executive of Keep Britain Tidy, one of the members of the consortium, said: “There is no doubt that introducing a deposit refund system would reduce littering in this country but, until now, there has been a concern that it would have a negative impact on cash-strapped councils. According to a new report, every day 35 million plastic bottles and 20 million aluminium cans are sold across the UK. Samantha Harding, litter programme director at CPRE, said: “There are no longer any valid arguments that deposit refund systems don’t work and the environmental case is crystal...
