VACUUMSCHMELZE presents its materials expertise in Cores and Components at Tube & Wire 2012

VACUUMSCHMELZE GmbH & Co. KG (Hanau) will again attend the 2012 Tube & Wire (26 to 30 March) in Düsseldorf. At booth A49 in Hall 16, the Hanau-based company will once again live up to its credo "Advanced Materials - The Key to Progress". VAC aligns the materials it produces to the needs of its customers, optimizing technological and price/performance aspects and supplying the finished products with the precise material properties and dimensions required. For the company's customers, this means outstanding flexibility in addition to the possibility to deliver high-grade, specialist materials in batch sizes as small as 100kg. Same basic elements - broad range of products VAC uses iron, nickel and cobalt as the main elements to manufacture wire products with widely varying properties. For example, the company supplies a range of nickel-iron and cobalt-iron alloys in the sector of soft magnetic applications, in which requirements for high precision and miniaturization are increasingly advanced. MUMETALL®, featuring maximum permeability of 250,000, is a key element in power sensors. Cobalt-iron alloys such as VACOFLUX®, on the other hand, offer ultra-high saturation polarization of up to 2.35 T and are thus ideal for electromagnetic actuators with high dynamic response or electro magnets. In addition to soft magnetic alloys, VAC also produces ductile permanent magnets. CROVAC®, for example, is a highly ductile material that can be supplied as wire or trimmed pins, with properties that also enable it to be used for more complex geometries requiring bending or other processing. Unlike highly brittle rare earth magnets or expensive AlNiCo magnets, CROVAC® pins represent a high-quality yet affordable alternative for applications such as bi-stable relays. Further technological highlights from VACUUMSCHMELZE certainly include the company's ultra-high-strength spring materials. These VAC alloys offer unique combinations of attributes: for example, NIVAFLEX® is used for the mainspring in any high-quality mechanical timepiece, as the only material offering hardness up to 3000 MPa plus residual ductility that ensures ultra-long life even for springs that are subject to high alternating loads. A recent development by VAC is DURACON® 17A, a contact spring material with hardness of up to 1800 MPa plus electrical conductivity of 6 MS/m (10% IACS). This material is the first high-strength, eco-friendly alternative to copper/beryllium alloys. While VAC spring materials are optimized for maximum strength, the key property of its melt-in alloys is defined thermal expansion, a vital factor in the interaction of glasses and ceramics. The range of VACOVIT® and VACON® alloys deliver precisely adjusted expansion coefficients in fine increments from near-zero to approx. 12 ? 10-6 K-1. VACUUMSCHMELZE also develops completely new custom alloys for specific applications, such as VACON® CF8 and VACON® CF25, both of which combine high conductivity and highly temperature-dependent resistance (0.1 to 1.1 mWm). In addition, VACON® CF25 is a melt-in alloy which is effective in high-conductivity glass sealed power entry points in vacuum chambers. This sophisticated high-performance material has replaced conventional copper core wires and delivers far superior electrical and thermal conductivity.
