Second, the physical properties of neutral refractory 0.670W. (MK) -1, electrical insulation 200kv, radioresistant 5 × 1014 neutron / cm2 contrast ratio. Another chemically neutral refractory composition, structure, and kaolin similar structure, but also has some of the characteristics of clay minerals refractories brand, or scattered good suspension, fine grain color white, sticky, etc. in an aqueous medium and organic solvents. Thus, a variety of characteristics of both neutral refractories and refractory clay minerals minerals. Auto body car had accounted for 30% of the quality of HE, the car itself, about 70% of the fuel is used in the body mass of refractory agent, so auto body aluminum vehicle fuel economy is essential to improve. Audi plant material as early as 1980 on Audi80 and Audi100 uses aluminum alloy doors and expanding applications. 1994 Audi plant material spend € 8 million to establish the aluminum center (1994 ~ 2002) refractory species, two years ago, has been renamed "Audi aluminum based sauce and the severity of the center." 1994 developed the first generation of AudiA8 aluminum space frame structure (ASF), ASF body over the strength and safety of modern cars steel body. But the quality of the car itself reduced about 40%. Then in 1999 the birth of AudiA2, became the first to adopt the technology of mass production cars. In 2002, Audi Aluminum and Lightweight Design Centre has realized the second generation AudiA8 birth.
