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...

China, the dominant producer and exporter of petcoke, is set to witness a drop in its total petcoke export in 2017. Due to the recent environmental pollution control crackdowns in China, the supply of this critical raw material of aluminium, has become tight in the domestic market. However, CPC demand in China is forecast to increase by 852,000 tonnes year-on-year leading to a deficit of 78,000 tonnes in 2017. Petcoke or petroleum coke is a by-product of the oil refining process, which when subject to calcination (further heat processing) yields calcined petcoke. CPC is a rich source of carbon and is used to produce anode for the electrolytic reduction process of aluminium smelting. According to reliable industry sources, China exported about 704,264 tonnes of CPC in H1 2016, of which...

Panasonic Automotive and Industrial Systems Europe, a manufacturer and supplier of electronic components, devices and modules up to complete solutions for a wide range of industries, has introduced eight new conductive polymer aluminium solid capacitors. The new SXE and SXV series of aluminium capacitors are used for applications such as industrial, digitalisation, control system, noise filtering, and power supply. Andreas Lapucha, Product Marketing Manager Capacitors at Panasonic, said, “Due to their superior high frequency characteristics, our new SXE and SXV series capacitors are ideally suited for use as a decoupling or input smoothing capacitor, or as a filter capacitor. The components offer great space and cost savings and require no voltage derating.” Both the series of capacitors...

Hydro has issued a notice of force majeure to its bauxite customers as Hydro will not receive the full contracted volumes from its supplier, MRN, due to lower production at the bauxite mine. This will affect Hydro's bauxite deliveries to customers. MRN, where Hydro has a 5% ownership and additional 40% offtake, is experiencing problems with its tailing systems due to lack of water. The lack of water is caused by a very dry period in the region. This is expected to reduce production of bauxite from a previously expected level of 17-17.5 million mt to around 15-15.5 million mt in 2017. As the production shortfall is mostly related to dry bauxite for the export market, it is not expected that production at the Alunorte alumina refinery will be affected. MRN has a nameplate capacity of around...

Odisha Mining Corporation (OMC) has floated tenders to start operations from its Kodingamali bauxite lease.In the first year of operations, OMC, a state-run entity, targets to produce 1.5 million tonnes of bauxite. From second year onwards, the output is set to expand to three million tonnes per annum (mtpa), said a government official close to the development. The commencement of operations at the Kodingamali mine would mark OMC's foray into bauxite mining. Though OMC has a few bauxite mines in its kitty, yet the mines have not been able to start operations as they lack the regulatory clearances. Bauxite deposits at Karlapat and Sasubohumali are reserved in OMC's favour but these have not opened up for want of environment and forest clearances. Bauxite mining from Kodingamali is also...

Nissan Casting Australia (NCA) will produce die cast aluminium parts for the new Nissan LEAF, the next evolution of its zero-emission electric vehicle. Dandenong South in Victoria secured the contract because cheaper countries could struggle with the highly technical nature of the items, reported by GoAutoNews reported. The two key die cast aluminium parts will be supplied to Japan. The 200-strong workforce at the Nissan Casting Plant produces high-pressure die-cast aluminium final drive components, and oil pan engine and manual transmission parts, which are all exported globally, according to the company. “The Dandenong manufacturing plant produces over 2.5 million die-cast aluminium parts and 16,000 tow bars yearly, with an approximate export sales value of over $82 million annually,”...

Talum d.d. based in the Slovenian town of Kidričevo has ordered a continuous homogenizing furnace and a helical ultrasonic testing station from Hertwich. The new plant will start operation in July 2018 and will almost double the homogenizing capacity of the group. Founded in 1942, Talum started operating a newly built electrolysis in 1954, which was expanded continuously in the following years. The production has since been modernized and the product range expanded. One of the most important – and expanding – product lines of the group are aluminum extrusion billets. The semi-finished product range includes standard AlMgSi alloys. For the homogenization of these materials, the continuous homogenizing furnace, developed by Hertwich, offers a number of advantages.

Coal tar pitch production is growing globally driven by the ferrous and non-ferrous metal sector growth. A critical binder material for anode production required in aluminium smelting through Hall Heroult method of electrolysis, CTP remains in high demand where prebaked technology is used for making aluminium. A couple of decades back West Europe and North America used to be the base of CTP production; but over the years the base has shifted to China. Today, CTP forms approximately 76 per cent of China’s total coal tar market, and coal tar pitch export forms a significant part of its GDP. China exported 1,44,405 tonnes of CTP in the first three months of 2017. In March alone, the export quantity peaked at 85,128 tonnes. Following the wide-scale environmental pollution control checks and...

United Wagon Co. in Russia has obtained certification for its Type 19-9549-02 grain hopper wagon. This particular wagon uses high-strength aluminium alloy in its roof, which cuts its weight by more than 1 tonne in comparison to the steel model. It also offers corrosion resistance and increases the load capacity of the wagon. This aluminium alloy design increases the capacity of the 25 tonne axle load wagon to 77 tonnes or 120 m3. This will provide an efficient transport medium for lightweight food grade products including meal and pressed seed cake. Arconic Russia’s BobTail clamping bolts are used to attach the aluminium roof to the steel body of the wagon, which are immune to high levels of vibration. United Wagon Co. and Arconic Russia are also working on an aluminium tank wagon design....
