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...

Aluminum "pull tabs" from soda cans can be easily recycled and the fund collected from that can be used for various charity works. At Russellville, proceeds from soda can tab recycling are being used to help many children who are sick and in need of care at Shriners Hospitals. Those aluminium "pull tabs" from soda cans should be pulled off before throwing the can into the recycling bin. One can put them in a box, a jar, a plastic container, or any other storage place and save them throughout the year. Once the collection is complete, one can bring them to Hickory Hill Florist in Russellville and they will take care of the rest. On Saturday, Dec. 16, members of the local Shriners took 482 pounds of tabs collected this year to Dean's Recycling. The proceeds, as part of the Shriners Tab...

The Aluminum Extruders Council (AEC) was encouraged by the initiation of the 232 Investigation and the implication that President Trump was going to take on the greatest risk to the future of the U.S. aluminum industry - China. AEC members stood up to China’s illegal and unfair trade policies with the imposition of antidumping orders in 2011. As a result of these orders, AEC member companies have made significant new investments that enabled the industry to offer new products and technologies for transportation, defense, automotive light-weighting, and many other applications. However, the Administration risks ignoring the China problem by imposing trade restrictions on imports from other countries which could shut off the supply of primary aluminum and threaten the ability of downstream...

According to the latest USGS release on Bauxite and Alumina in the Third Quarter 2017 , imports of crude and dried bauxite by the U.S. in Q3 2017 were 914,000 tonnes, 13% more than the revised total of 812,000 tonnes in the second quarter of 2017. However, on a YoY basis, import of bauxite drops 20% from the amount in the third quarter of 2016 and 68% less than those in the third quarter of 2015. Imports of crude and dried bauxite in the third quarter of 2016 were 1.14 million tonnes. Imports of crude and dried bauxite in the first quarter of 2017 were 790,000 tons, 47% less than 1.51 million tonnes in the first quarter of 2016. Though the imports are falling YoY, they are up quarter on quarter in 2017. The decrease in bauxite imports YOY is attributable to the temporary and permanent...

Chinese coal prices, which have fluctuated between CNY550-750/t (US$83.60-114/t) in the past two years, are set to ease going forward, as it is anticipated that the country's policy makers will allow Chinese miners to increase production again in response to prices reaching the upper range of US$100/t in Newcastle. Coal producers outside China are also ramping up production, tempted by the higher prices realised in 2017. US exports have been reported to expand at the highest pace in the last five years, while in Colombia and Australia coal supply is improving. Meanwhile, seaborne demand from key importers such as China and India is anticipated to contract as domestic output expands. The resulting oversupply is expected to lower prices for seaborne coal with Newcastle prices falling from...

The dichotomy of alumina and aluminium remains on the same page as alumina is falling on the price curve while primary aluminium is recovering from the recent fall that started in November. Spot alumina price in China has dropped from the year’s high of RMB 3730/t in November first week to RMB 2881/t today. Domestic alumina prices have also slipped to RMB 2850/t today. Aluminium price rise has been slow due to falling prices of alumina. The contract rose overnight yesterday December 20 on news of potentially lower alumina output due to natural gas shortage. SMM however observes that alumina production would not be impacted much as most producers use coal gas as fuel. Another factor that is keeping alumina prices low is its high inventory driven by slow demand from smelters. Spot alumina...

U.S. President Donald Trump’s new security strategy bolsters the case for trade actions to protect U.S. economic interests on national security grounds, including possible import tariffs on steel and aluminium, a senior Trump administration official said on Tuesday. The strategy document released on Monday did not specifically mention the Commerce Department’s “Section 232” investigations into whether rising steel and aluminium imports represent a threat to national security. With recommendations due in January, the probes could lead to broad tariffs or import quotas under a Cold War-era trade law. The official said the document made clear that Trump considered economic strength to be an integral part of national security and “formalizes” the link between the two. The 232 probes on steel...
