3M ACCR Conductor Resists Corrosion and Retains Strength in 11-Year Field Test - 0 views

  • Corrosion can affect the weight and strength of conductor materials. Tests performed recently on samples of ACCR conductor strung in late 2002 showed no appreciable loss of either tensile strength or weight. Tensile strength remained between 105 and 107 percent of rated breaking strength. Examination of core wires with both optical and scanning electron microscopes showed no indications of corrosion or pitting.

Leoni will continue to expand its commercial vehicles business with innovative products... - 0 views

  • “We have developed several new solutions, which can provide clear weight and cost saving opportunities to manufacturers of such commercial vehicles as  trucks, buses as well as agricultural, industrial and construction equipment”, stated Dr Andreas Brand, member of Leoni AG’s Management Board with responsibility for the Wiring Systems Division. “We are confident that we will grow our business with the CV industry by more than five per cent per year until 2025.”Alternative conductors save weight and costIn terms of weight optimisation, Leoni can reduce the harnesses’ weight by replacing conventional wires. Alongside copper wires with smaller cross-sections, the Company provides the CV market with a range of wires made of aluminium for the power segment, i.e. with a cross-section between 10 mm2 and 110 mm2 and even larger. Although the aluminium conductors have a larger cross-section in order to deliver the same electrical conductivity, aluminium technology results in a noticeable weight reduction. On its booth, Leoni will show its busbar, a solid aluminium conductor, which can be bent in three dimensions and weighs only about half as much as the conventional copper component.Leoni will also show various conductor solutions based on copper. These can be used where mechanical strength as well as electrical conductivity is required. For example, a copper wire with a cross-section of 0.75 mm² could potentially be replaced by a smaller wire cross section, such as a 0.50 mm² or a 0.35 mm². Thanks to the use of less conductor material, Leoni’s customers can not just reduce the weight of their vehicles, but also benefit in terms of cost savings.

Dr. Copper Has Bad News for Mining Stocks - 1 views

  •  
    "Besides an imbalanced market, renewed U.S. dollar strength could also weigh on copper prices. Additionally, there is also the rising threat of substitution over the long term. Nomura's Jones estimates around 75% of demand could be at "medium or high risk" of substitution." In many instances, copper could be replaced by aluminum, which is markedly cheaper than copper even after adjusting for differences in conductivity. Jones sees air conditioning and auto manufacturing as key areas where the compelling economics of aluminum pose a major threat to copper demand."

Kulicke & Soffa Announces Agreements to Acquire Orthodyne Electronics and Divest its Wi... - 0 views

  •  
    Kulicke & Soffa Industries Inc (K&S) has announced that the company has entered into definitive agreements to acquire substantially all of the assets of Orthodyne Electronics Corporation, a supplier of wedge bonders, and sell the K&S wire business unit to WC Heraeus GmbH, a precious metals and technology group. Under the terms of the Orthodyne agreement, K&S will fund the acquisition of Orthodyne with approximately 7.1 million shares of K&S common stock, plus $80 million in cash. If the transaction is not consummated by October 31, 2008, the purchase price will be approximately 19.6 million shares of K&S common stock and no cash. The deal includes possible earn-out consideration up to an additional $40 million in cash if certain financial objectives are met by Orthodyne over the next three years. The closing of the transaction, which is expected within approximately 60 days, is subject to certain working capital adjustments and closing conditions, including regulatory approvals. "The acquisition of Orthodyne is in line with our stated strategy and positions K&S to capitalize on our strengths in equipment manufacturing and further cement our position as the leading supplier of interconnect solutions," commented Scott Kulicke, Chairman and Chief Executive Officer of K&S. "Orthodyne is a fast growing, profitable market leader and provides us with deeper penetration into the discrete side of the semiconductor market, particularly in the attractive power management and hybrid module markets."

    RUEIL-MALMAISON, FRANCE, August 15, 2008. Schneider Electric has signed a CAD 498 million definitive arrangement agreement with Xantrex Technology Inc for the acquisition of all common shares of Xantrex. Xantrex is said to be a top three global player in the solar and wind inverter market with strong growth potential. It also has a leadership position in the North America. Awaiting approval from Xantrex shareholders, the deal is expected to be closed by October 2008. Schneider Electric says it expects to realise significant synergies in acquiring Xantrex, leveraging the strengths of both companies. Xantrex provides experience in advanced power electronic technology for renewable energy, and dedicated solar and wind channel access. Schneider Electric boasts a wide international footprint with solution centres and leverage with APC in purchasing, technology and operations. Xantrex Chairman Mosaadiq Umedaly comments: "We think it is the best way to develop our business, taking advantage of our leading technology, products, market knowledge, and distribution channels together with Schneider Electric's global sales, service, supply chain, and solutions capabilities."

    China has stopped stockpiling metals, according to reports in the Chinese media. Will this put the cap on the recent strength in base metals prices? The AFP reports that, "China has been building its inventories of metals, including 235,000 tonnes of copper, over recent months, Caijing magazine reported on its website over the weekend, citing Yu Dongming, an official with the state economic planner."

New Method Used to Synthesize Cu-Based Nanocomposite - 0 views

  • In this research, we added silicon carbide powder of micro and nanoscales to copper by means of friction stir processing in order to reinforce its strength and resistance to surface erosion.
  • "It is possible to increase the strength base and resistance to erosion up to 3 times and 10 times respectively with respect to the material substance. It is also possible to give properties such as semi conduction or other physical properties to the desired material with regard to its application," he added, explaining about the results of the study.

KME sees flat growth and more substitution - 0 views

  •  
    Riccardo Garre the Chief Executive officer of KME Group SpA, the Italy-based manufacturer of copper semi-fabricated products, said in an interview with Bloomberg that he expects the company's production of copper and alloy semis to be 435,000t in 2013, unchanged from 2012, and 10% lower than in 2011. The Chief Executive said "to assume that in 2013 the volume will be exactly the same as in 2012, it means it's really a negative vision," although he did note some strength in flat-rolled copper and alloys used in the automotive and electronics industries. In the interview, he also said he believed slowing economic growth had prompted manufacturers to look for cheaper alternatives to copper semis, such as aluminium and plastics.

US - Southwire: US residential construction industry has bottomed-out, signs of weak re... - 0 views

  •  
    Southwire Co. Inc., a US cablemaker with a focus on building wire production, said that the US residential construction industry has bottomed-out after near-continuous contraction since being heavily impacted by the global economic crisis in late-2008. The company said that it is now necessary to use statistics on housing area under construction in order to analyse and pre-empt demand as government figures on housing starts cause an overestimation of the strength of the recovery in wire and cable demand. This is due to homebuilders more frequently electing to construct smaller homes, requiring less wire and cable than average-sized homes.
