    PPG Selected for DOE Partnership to Develop Adhesives for Lightweight Vehicles

    Vehicle manufacturers are exploring the use of aluminum, high-strength steel, magnesium, carbon-fiber composites, and other lightweight materials to reduce vehicle mass and improve fuel economy. This approach requires new adhesive chemistries that will mitigate corrosion and thermal expansion issues associated with joining dissimilar materials. PPG was selected for a U.S. Department of Energy (DOE) partnership, […]

    New Dovetail Process Joins Aluminum to Steel for Lightweight Combat Vehicles

    Researchers at the Pacific Northwest National Laboratory (PNNL) have developed and successfully tested a novel process — called friction stir dovetailing — that joins thick plates of aluminum to steel. The new process will be used to make lighter-weight military vehicles that are more agile and fuel efficient. According to the U.S. Government Accountability Office, the […]

    New Extrusion Process for Manufacturing Magnesium Car Parts

    Magnesium is 75% lighter than steel and 33% lighter than aluminum. As the lightest of all structural metals, magnesium has a lot of potential for lightweighting cars and trucks in the aim of improving fuel economy. However, auto makers have been challenged in their attempts to incorporate magnesium alloys into structural car parts. The Department […]
