<strong>TeroMatec®</strong><strong>TeroMatec®</strong> MANUFACTURING FACILITIESThe <strong>TeroMatec®</strong> range of high performance coredelectrodes are formulated, developed and manufacturedin <strong>Castolin</strong> <strong>Eutectic</strong>’s own modern plants usingspecially designed production equipment and proceduresin accordance with ISO 9001 and EN 29001quality assurance standards.Each <strong>TeroMatec®</strong> batch after wire drawing and baking,is weld tested for consistent chemistry, properties& operability before precision spiral spoolingand protective packaging for stock.metal strippre-forming rollfluxfinishing rollscore wireø 1,2 mmø 1,6 mmø 2,4 mmø 2,8 mmSelf shielding flux ingredients,arc ionising stabilisers, finegrain inoculants, powerful deoxidisers,metallurgical refiningagents, selected alloying elements,carbide compounds, etc.Steel stripSELF SHIELDED PERIPHERIC ARCUNIQUE ANTI-WEAR ALLOYSSolid Mag wires can only be manufactured in metallurgicalalloys which can be cast and easily drawndown to final diameters. The <strong>TeroMatec®</strong> cored electrodeconcept completely overcomes such limitationsand unique metallurgical alloys have been formulatedwith high density, ultra-hard micro constituantsin Fe matrices. Thus the wide <strong>TeroMatec®</strong> alloy rangeprovides cost effective solutions for most wear problemsfound in industry.Thanks to <strong>TeroMatec®</strong>’s self shielding and high current density characteristics,it can be welded at lower welding currents than a solid wire whilstkeeping a stable metal transfer across the arc due to ionising elementsin the core. Additionally, the lower heat input and presence of powerfuldeoxidising fluxes means that <strong>TeroMatec®</strong> weld deposits have better bonding,lower dilution, superior microstructure properties and minimal heataffected zones for maximum service performance.4Stronger with <strong>Castolin</strong> <strong>Eutectic</strong>www.castolin.com
