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...

Scientists have designed an ultra-light form of aluminium that floats on water, paving the way for novel uses of the material in future spacecraft and automobiles. In its conventional form, aluminium is denser than water. Aluminium spoons will a sink to the bottom if thrown in water. Researchers from the Utah State University (USU) in the US restructured the common household metal at the molecular level using computational modelling to design an ultra-light crystalline form of aluminium that's lighter than water. The team's calculations confirmed such a structure is a new, metastable, lightweight form of crystal aluminium. The material has a density of only 0.61 gramme per cubic centimetre, in contrast to convention aluminium's density of 2.7 grammes per cubic centimetre. "That means the...

Linde Group owned Linde Gases has launched the ARCLINE PP, a novel automated welding process that produces highly efficient aluminium welds by combining the best of existing aluminium welding technologies in one comprehensive package. Linde’s technology team has designed ARCLINE PP eliminating the compromises made while choosing between Tungsten Inert Gas (TIG) welding and Metal Inert Gas welding (MIG). While the first process ensures high quality at longer weld times, the latter gives faster weld times but lesser aluminium weld strength and integrity. According to Linde Technology, ARCLINE PP features a positively energised tungsten electrode that provides constant cathodic cleaning of the welding area, which reduces the risk of inclusions and minimises the need for pre-weld cleaning....
The leading integrated aluminium producer of India, National Aluminium Company Limited (NALCO), has announced plans to diversify into areas like merchant mining, green power, and caustic soda to withstand downturns in the global metal market and sustain profitability in the long run. The New Business Model (NBM) which encompasses “immune” sectors like IPP, rare metal like titanium, recovery of iron from red mud waste (an alkaline waste of bauxite digestion), is envisaged to give a new dimension to the company’s growth plans. Nalco achieved highest-ever production with bauxite transportation of 68.25 lakh tonnes (achieving 100 per cent capacity utilization) in the financial year 2016-17. The figures even surpassed the previous best of 63.40 lakh tonnes. With the sluggishness extending in...
Vedanta- controlled Bharat Aluminium Company Limited (BALCO) has received notice for the closure of its 1,200 Mw power plant from the Chhattisgarh Environment Control Board (CECB). The closure notice has been issued over alleged green norms violation. CECB has asked the company to file a response within 15 days. The board would examine the response and then would ask the company to close its plant if result would find unsatisfactory. The closure notice states that ash slurry coming out of the damaged ash dam passing near the plant is polluting water in the Belgiri nullah (canal) that drains into Hasdeo river. The closure of plant that is located in Chhattisgarh’s Korba district is expected to have impact on the production of aluminium due to lack of power.
