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 prices are on a solid upward track. Although technical analysis by major global research firms indicate at a possible correction which might result in trend reversal, the higher prices, as of now, are turning out to be real boon for the Indian aluminium producers. Vedanta is expected to post a whopping 162 per cent increase in its Q1 profit; Hindalco’s standalone profit increased 28 per cent; and Nalco’s production was up by 6.5 per cent year-over-year. Higher metal prices signify improved realization. Even though cost plays critical in deciding a company’s profitability, it definitely helps in improving the topline. Hindalco Industries had flagged rising costs in their aluminium business; but thanks to the rising global aluminium prices, the company’s revenue increased by...

In what is considered the first instance involving a joint venture with a foreign government arm seeking insolvency, Anrak Aluminium, the joint venture between India's Penna group and UAE's Ras Al Khaimah Investment Authority (RAKIA), has moved the National Company Law Tribunal (NCLT). The move comes close on the heels of RAKIA serving an arbitration notice to the Indian government and Andhra Pradesh seeking either to fulfil commitment to supply bauxite or pay compensatory damages on its investment of $44.71 million. The development also comes weeks after the Andhra government decided to cancel the agreement that the Andhra Pradesh Mineral Development Corporation (APMDC) had entered into with Anrak Aluminium to supply bauxite during the erstwhile Congress government headed by YS...

The world’s largest aluminium producer China Hongqiao confirmed Monday, August 14 that it had closed 2.68 million tonnes of smelting capacity after Shandong Government ordered it to do so in an attempt to curb illegal capacity. The aluminium capacity closed by Hongqiao was spread over five projects. Neither Hongqiao nor any of its subsidiaries was charged a penalty by the authorities, Shandong Weiqiao Aluminum & Electricity said in a disclosure made to the Shenzhen Stock Exchange. Shandong Hongqiao is the sole shareholder of Shandong Weiqiao, and all the capacities closed are the newly added ones by these two companies and their subsidiaries. Presently, Hongqiao has a total aluminium capacity of 6.46 million tonnes per annum, which remains unaffected by the recent closures. As per August...

Jamaica is yet to get its due from its bauxite mining industry. The country with a sizeable bauxite reserve amounting to 2 billion tonnes ranks fifth after Guinea, Australia, Brazil, and Vietnam as one of the world’s top countries with rich bauxite reserves. As per 2014 U.S. Geological Survey data, Jamaica’s bauxite production stands at only 9.8 million tonne; which means the country remains largely untapped as far as its mining potential is concerned. No wonder, its bauxite export growth also remains stunted even after five decades of it becoming a mainstream bauxite producer. During the initial six months of the current calendar year, Jamaica exported 1.54 million tonnes of bauxite, according to the global export-import data based on a number of macroeconomic factors. The figure is in...

The Malaysian Anti-Corruption Commission (MACC) will examine the ports to restrict the export of bauxite in the country. MACC has been investigating illegal bauxite mining activities for weeks. MACC deputy chief commissioner (operations) Datuk Azam Baki said the halt would be difficult but necessary. MACC seized 10 million tonnes of bauxite stockpile worth RM1.28 billion. The areas where bauxite stockpiles were seized are located in Felda Bukit Goh and Kuantan Port. The seizure would prevent the bauxite from being taken out of the stockpile area. “They will have to comply with the notice. We can hold the bauxite stockpile in Pahang for 18 months, once the notices are issued,” Azam said. The commission also asked the Natural Resources and Environment Ministry (NRE) to cancel all Approved...

Due to huge aluminium capacity cuts by Weiqiao and Xinfa Group, alumina market in China is in surplus. SMM expects that due to inflows of surplus alumina from Weiqiao group, alumina prices will face continuous downward pressure. Weiqiao Group has announced that it will release alumina into the open market for sale. Moreover, Xinfa Group is already selling in the market and this might worsen the situation in the market. The weighted average alumina price in the four major domestic major markets remained unchanged week-on-week at 2,521 RMB/tonne on August 11. As updated by SMM, the major alumina and aluminium producers in China had two meetings last week to discuss future price trends of the materials.
