VIMANA B.V. is a Dutch startup company, active in design and manufacturing of advanced light-weight materials based on magnesium technology. A combination of light weight, high specific strength, and good manufacturability makes magnesium alloys a promising engineering material for the automotive and aerospace industries. Regarding passenger cars, the general rule is that about 86% of their total life time energy use from the time of production to the time of disuse or scraping is consumed by carrying their own weight and persons around. Therefore, vehicle weight reduction is one of the major means available to improve automotive fuel efficiency.
Magnesium is an attractive material for automotive use, primarily because of its light weight - 36% lighter per unit volume than aluminum and 78% lighter than iron. When alloyed, Mg has the highest strength-to-weight ratio of all the structural metals.
