Renault Samsung, Posco develop new car parts materialRenault Samsung Motors said yesterday it became the world’s first automaker to use magnesium sheet parts to mass-produce cars.
The Korean unit of French automaker Renault said that along with Korea’s largest steelmaker Posco, it invested 2 billion won ($1.9 million) over 19 months to develop the parts.
RSM said its magnesium sheet parts weigh 1.4 kilograms (3 pounds), 2.2 kilograms lighter than existing metal sheet parts.
The automaker said the newly developed parts have been used in a face-lift of its flagship SM7 sedan that will be unveiled next month. The company said the parts are used on the edge of the sedan’s backseat and trunk.
