Titanium and titanium alloys can offer substantial weight savings due to their high strength-to-weight ratio. A prime example is the ability to reduce the weight of valve springs and valve disks by up to 70% through the use of a titanium alloy. In addition, titanium is used for highly stressed components such as connecting rods, turbocharger wheels and shafts, pistons, and inlet valves. Due to its good formability titanium can also be easily formed into the complex geometries of exhaust systems.
Owing to its fatigue resistance titanium alloy Ti-6Al4V is well suited for use in engine valves subjected to high cyclic loads.
Nickel alloys stand out due to their oxidation resistance and creep resistance at temperatures of up to 950°C, making them excellent materials for use in exhaust manifolds, exhaust pipes, and even high temperature fasteners. In engine designs, they enable operation at higher temperatures and therefore improve efficiency.
