An automotive engine valve stem, engine valve and method of producing both. The valve includes a head and a stem joined to the head. Lightweight, high-temperature materials, such as titanium-based materials may be used to make up at least a the majority of the valve. These materials are combined with fabrication techniques that may vary between the head and the stem, where at least a part of the valve is made by dynamic magnetic compaction. While a majority of the stem may be made from a titanium-based powder material, its tip may be made of a high strength hardened material, such as a steel alloy. The valve head may be made by single press and sintering, double press and sintering, forging and machining, forging and sintering, and dynamic magnetic compaction and sintering.
