Mazda CX-5: first vehicle to use the st has ultra-high strength of 1800 MPa?

Mazda Motor Corporation, in collaboration with Sumitomo Metal Industries, Ltd.. Aisin Takaoka and Co., Ltd.., became the first automaker successfully manufacture automotive components from steel to ultra-high strength of 1800 MPa. This steel is extremely resistant inaugurates the CX-5, the new crossover SUV Mazda, which will be launched early in 2012 globally.

As part of its new production technique, Mazda uses a steel has ultra-high strength of 1800 MPa to realize the uphills beams has inside of the front and rear, beamed directly subject to deteriorations in case of collision. 20% stronger than their predecessors and weighing 4.8 kg less, these new beams shield is a key component of the new architecture alleviated highly rigid Mazda. It is in the context of its revolutionary development program of SKYACTIV technologies that Mazda has developed this new architecture body, which integrates a new energy absorbing structure and uses a steel has ultra-high resistance in an effort to gain weight.

The use of high strength steel can reduce the thickness auto parts while maintaining a level of resistance high. This results in a significant reduction in the weight of the vehicle. It is particularly important to reduce the weight of beams shield because, being incorporated into the body structure at the most distant from the center of gravity of the vehicle point they greatly affect their weight on dynamic performance and responsiveness. They must also be robust to ensure adequate protection in case of collision. For all these reasons, Mazda seeks to develop a method for producing a large series of parts from a more resistant steel.

However, a more robust material is, the less flexible and therefore less energy it absorbs crash. To overcome this, Mazda conducted extensive research on the manner in which the shield beams deform upon impact studies, and created a new concept to absorb the energy more efficiently. Concerned also that the CX-5 offers maximum resistance to grace his shields, Mazda collaborated with Futaba Kogyo Co., Ltd.. to optimize the welding techniques and establish a reliable manufacturing process perfectly.

For the future, Mazda is more than ever determined to reduce the weight of its vehicles and improve their dynamic performance. At the same time, Mazda guarantee a level of rigidity pupil has their pension and excellent shock resistance to offer to all its customers with outstanding driveability and outstanding performance in matters of safety and environmental protection.
