TECHNOLOGICAL CHALLENGES
• Advantages of magnesium:
• Similar mechanical and thermal behaviour compared with aluminium alloys
• 30% weight reduction when substituting aluminium by magnesium
• Disadvantages
• High reactivity of molten magnesium with oxygen and ceramic mould Oxides, mould burning
• Unknown rheological behaviour of the molten magnesium inside the ceramic mould
• Technological challenge:Technological challenge:
• Develop a specific investment casting process for magnesium alloysoxides

MARKET CHALLENGES
• TARGET MARKET: Transport industry
• 30% lighter products with advanced mechanical properties reduction on fuel consumption
• Weight reduction improves vehicle performance by enhancing acceleration/deceleration.Weight reduction improves vehicle performance by enhancing acceleration/deceleration.
• Magnesium parts can be tuned to critical frequencies where noise, vibration and harshness arereduced
• Lighter structures can be removed and/or reconfigured to allow easier egress and ingress; e.g.g te st uctu es ca be e o ed a d/o eco gu ed to a o eas e eg ess a d g ess; e ga 3rd-row magnesium seat is 18 Kg. lighter than a heavier steel fabrication.
• Magnesium castings can have reduced manufacturing cost vs. steel, especially for productionvolumes of less than 200.000 units/year. For example, a 30-part steel cross-car beam requires30 i t l / th t i i h l 630 expensive tools/gauges; the cast-magnesium version has only 6.
• A one-piece cast-magnesium cross-car beam can reduce dimensional error vs. stamped/weldedsteel elements.
M i h hi h t th tiff th l t bilit d th l d ti it l ti• Magnesium has higher strength, stiffness, thermal stability and thermal conductivity vs. plastic;higher specific strength, ductility and impact resistance vs. aluminum as well as better dampingand dent resistance vs. steel

CONCLUSIONS
• ALFA experience inMANUNET projects is very satisfactory:
• 3 approved projects in 2007 and 2008 (out of 3 presented)
• 1 project presented to MANUNET 1st stage in 2009
• More to come• More to come
• MANUNET projects allow transnational cooperation avoiding difficulties linkedto conventional large-scale European projects
• MANUNET is a extremely convenient tool as a first experience in European• MANUNET is a extremely convenient tool as a first experience in Europeanprojects for small-medium sized companies
Everything seems wonderful, but:
• Be patient with administrative process!!!
