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 slid further down. With the price support from two of aluminium’s key raw materials coal and alumina weakening, the light metal is unable to reverse the downtrend, even when aluminium stocks in LME warehouses are declining. On the other hand, demand growth has slowed down. All these factors are expected to weigh on LME aluminium prices in the near term. As on November 21, LME official cash buyer aluminium price (Bid Price) stands at US$2,060 per tonne, cash seller & settlement aluminium price (Offer price) is US$2,062 per tonne, 3M Bid Price is US$2,078 per tonne, 3M Offer Price is US$2,080 per tonne, Dec1 Bid Price is US$2,125 per tonne, and Dec1 Offer Price is US$2,130 per tonne. LME aluminium Opening Stock or the LME aluminium inventory level stands at 1141700 tonnes,...

On November 17, 2017, Real Industry and its U.S. subsidiaries have filed for voluntary bankruptcy. The company also confirmed that they received interim approval from the U.S. Bankruptcy Court for all of the “first day” motions related to their filings. The secondary aluminium producer expects to continue with its operations with grants from the Court on an interim basis. The grant gives authority to the Company and Real Alloy to make payments to suppliers and service providers as well as to pay employees wages, salaries and benefits during its reorganization effort under Chapter 11. Real Alloy expects to get approval for $110-million asset-based lending facility and up to $85 million through debtor-in-position (DIP) financing.

A00 ingot price has experienced the biggest drop in recent time today when the average price stood at RMB 14,860/t. As updated by Shanghai Metals Market, the primary ingot price registered a drop of RMB 250/t. The price is expected to range within RMB 14,840 – 14,880 per tonne. Aluminium price has been surging throughout 2017. The price rise was so far driven by supply-side reforms in China and environmental restrictions. On the other hand, increase in the price of prime raw materials like alumina and coal was another factor supporting the growth in aluminium price. As per SMM data, average full production cost of domestic refined aluminium enterprises in November 2017 is RMB 16,033 per tonne, up 4.5 on yearly basis. However, the recent downturn in aluminium price is mostly driven by drop...

Aluminium can export from UK is slated to witness a significant drop in 2017, after a gradual year-on-year decline since 2015. The largest beverage can market in Europe- UK reached 70 per cent aluminium beverage can recycling rate milestone in 2016. At a time when the country is endeavouring to make the European metal packaging sector's ambition of reaching and exceeding an average 80 per cent metal rate by 2025, this drop in export volume is somewhat baffling. Global export-import data shows, UK’s aluminium can export took a huge leap from 9565 tonnes in 2014 to 38,742 tonnes in 2015. Since then, export volume has been dropping. Last year, aluminium can export totalled 36629 tonnes, down 5.45 per cent year-on-year. It is estimated that UK will export 27508 tonnes of aluminium cans in...

Noble Group, who acquired interest in Jamalco refinery from Alcoa in 2014, is considering the sale of Jamalco alumina refinery. According to news reported by Bloomberg, Global commodities company Noble Group sits down with shareholders this week for crisis talks to restructure about $3.5 billion in debt, and the refinery is expected to play a crucial role in managing the debt. Jamalco is a joint venture between Noble Group and Clarendon Alumina Production (CAP). In December 2014, Noble Group bought 55 percent stake of Jamalco and remaining 45 percent is owned by Clarendon Alumina Production Ltd. (CAP). As per Bloomberg report, alumina refinery is likely to be the company’s most valuable remaining physical asset after the sale of its global oil and gas trading businesses. However, the...

Currently Aditya Birla Group remains the largest aluminium producer in India with a total combined capacity of 1.32 million tonne of aluminium by Aditya Aluminium and Hindalco. However, Vedanta is on the right track to touch 1.6 million tonne capacity mark this year surpassing Hindalco. Vedanta has recently reported record half yearly production of 753,000 tonnes, up 39% YoY. This was attributed to continued smelter ramp-up in Balco and Jharsuguda. The company reports a current run-rate of 1.6 tpy (excluding trial run production). The company, which produced 1.21 million tonne of aluminium across its two facilities in Jharsuguda and Korba in FY2017, is on course to clock an annual output of 1.6 million tonne this year. "As a group, we will be producing 1.6 million tonne of aluminium in...

LME aluminium is extending its declines. With the downward tendency of alumina and coal prices already setting in across China market, the light metal is unable to draw support and reverse the downtrend. From US$2,077 per tonne on November 17, LME aluminium has dropped further to US$2,067.50 per tonne after night trading on Monday, November 20. LME aluminium stocks are falling in tandem as well. This could affect regional aluminium premiums and spreads, market sources opine. Most of the global participants are of the view that there was room for further fall for LME aluminium in the near term. As on November 20, LME official cash buyer aluminium price (Bid Price) stands at US$2,067 per tonne, cash seller & settlement aluminium price (Offer price) is US$2,067.50 per tonne, 3M Bid Price is...

According to the Aluminum Association’s annual key performance indicators report for one of the widely used consumer products – the aluminium can, U.S. UBC recycling rate reported a decline in 2016. The indicators included Industry Recycling Rate, which measures the amount of used aluminium can scrap recycled by U.S. aluminium producers as a percentage of total can shipment. Another indicator is Consumer Recycling Rate measuring the amount of aluminium can scrap recycled domestically as a percentage of cans available for recycling in the U.S. The rate indicates the performance of municipal recycling programs and is also dependent on YoY fluctuations in metal flows and commodity prices. For the industry recycling rate, the Association surveyed UBC melting facilities including can sheet...
