The innovative car concepts placed more requirements to car manufacturers and suppliers with the growing public awareness on fuel consumption and car emissions.In spite of some customers demand on high performance,car size,extra comfort that boost the weight spiral,car companies try to respond by new concepts,including the consequent light-weight car design to reduce the car weight or carry out the usage of elect
Zuoyuan high-silicon aluminum alloy material (silicon content 27%-70%), cost-effective, high practicability, by increasing the supersaturation of Si in the aluminum matrix, the formed silicon particles reinforced aluminum matrix composite material. High-silicon aluminum alloy materials with different properties can be obtained by adjusting the volume fraction of silicon, with low thermal expansion coefficient CTE
Property Characteristics of Hypereutectic Al-Si alloy - Low coefficient of thermal expansion;lower weight;dimensional stability;higher thermal conductivity;Excellent wear-resistance and corrosion resistance.The hypereutectic Al-Si alloy possess these combination performances which extremely suitable for manufacturing lightweight and wear-resistance parts.The properties of hypereutectic Al-Si a
Metal optics made of Aluminium 6061 have been widely used to fulfill the demands of an athermal instrument design. Diamond turned metal mirrors are standard optical components in mid infrared astronomical instrumentations working at cryogenic temperatures. Structures and optics can be made from the same material (aluminium) to avoid thermal stress due to different CTEs. However, surface roughness, scattering beh
