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...

The year 2018 is shaping up to be a big year for truck lovers. All the new 2019 models are being readied to be unveiled sometime around next year. The Detroit auto show being the carmakers’ favourite platform for showcasing their new machines will definitely see a few of these launches. Company specs say many of these new-age trucks will wear significant aluminium accents, the material of choice for lightweighting. Following are the top two trucks with aluminium exteriors awaited in 2018: The 2019 GMC Sierra, Chevy Silverado is the first truck to make a grand exit from the GM trucks’ stable. It is expected to arrive with an updated EcoTec3 powertrains and 10 speed automatics co-developed with Ford, and possibly a new diesel engine. There are also credible hints of the truck bearing...
With the introduction of reduction plan during heating season of Henan, Shandong and Shanxi Provinces, the affected annual capacity of electrolytic aluminium is expected to exceed 2.6 million tonnes. Since restarting of old capacity and newly-increased capacity are on the line, so production limit under high inventories will not cause short supply. The resistance of rise of Aluminium price in the long term has increased after mindset change. In the short term, with recovered consumption and production limit of electrolytic aluminium ahead of schedule, inventories will drop, which will continue supporting aluminium price. The amount of rise will depend on impetus of capital. Prices of A00 aluminium ingot have registered a slight rise from RMB 16,100/t to stand at RMB 16,130/t today. A00...
ALTEK has successfully installed a large capacity salt slag recycling plant, ALUSALT, as a demonstration unit, in Northern Europe at an aluminium recycling operation, where it is currently in the final stages of commissioning and optimisation, a press release from the company has confirmed. The plant has successfully taken salt slag, removed the salt, re-crystallised the salt for re-use, and generated oxides (NMP) that can be used in various markets. The company will commercialise the new technology in 2018. Usually aluminium metal units are recovered from aluminium scrap and drosses using the rotary salt furnace (RSF) process, a process that produces salt slag as a bi-product. This is the easiest and most cost effective way to recycle scrap and aluminium dross. Typically, salt slag...

Alcoa Corp. sees Chinese cuts in aluminum production returning the global market to “relative balance” as the Asian nation’s supply-side reforms begin to bite. The largest U.S. aluminum producer reduced its global surplus forecast for the lightweight metal this year as China appears to be holding to its promise to curb capacity to meet pollution-control targets. “The improvement is mostly due to planned and actual curtailments in Chinese smelting capacity as well as increased Chinese demand,” Alcoa said Wednesday in its third-quarter earnings statement. China will have a surplus of 1.8 million to 2 million metric tons of aluminum this year, Alcoa said in a presentation accompanying the earnings report. That compares with a July projection for a surplus of 2.2 million to 2.4 million. As a...
The US based global institutional investment management firm York Capital has completed the acquisition of Delfzijl aluminium smelter. Executives from the smelter, which started as Aldel and was later renamed as Klesch Aluminium, met York management to seal the agreement over the re-start of the company this week, reports confirmed.

According to a recent update from SMM, one of the large-scale aluminium enterprises in Shandong plans to launch four new Achenbach 1850 aluminium foil mills, with annual capacity of about 30,000 tonnes. After China has taken up measures to cut primary aluminium capacity across the country, aluminium enterprises in China are looking at investing in the downstream sector. Shandong province has announced big slash in aluminum output by over 2 million tonnes. Downstream investment is also driven by projected growth in the automotive and construction sector in China. The said Shandong aluminium enterprise is also aiming at seeking high value-added aluminium products to ensure profitability. The factory has already been built and the equipment is going to be installed in the end of 2017. The...

Rio Tinto has been notified by the US Securities and Exchange Commission (SEC) that it has filed a complaint today in relation to Rio Tinto’s disclosures and timing of the impairment of Rio Tinto Coal Mozambique (RTCM). The impairment was reflected in Rio Tinto’s 2012 year-end accounts. Rio Tinto intends to vigorously defend itself against these allegations. The SEC has alleged in a civil complaint filed in the United States District Court for the Southern District of New York that Rio Tinto committed fraud by not accurately disclosing the value of RTCM and not impairing it when Rio Tinto published its 2011 year-end accounts in February 2012 or its interim results in August 2012. Rio Tinto believes that the SEC case is unwarranted and that, when all the facts are considered by the court,...
