MATERIALS

Good Fabrications was able to investigate the ageing of an Inconel 625 alloy exhaust manifold exposed to a Formula 1 racing environment.

Good Fabrications was able to investigate the oxidation response and microstructural evolution of an Inconel 625 alloy exhaust manifold exposed to a Formula 1 racing environment.

The design of an exhaust system is usually a trade off between engine performance, packaging, materials available and the fabrication techniques used.

Titanium Grade 1 is also known as the Commercially Pure Titanium and is one of the softest titanium grades with a very formability and excellent weldability.

Aluminium 6063 is an alloy used in most of the induction systems on high performance engines used in motorsports such as Formula 1 and touring cars.

Inconel (nickel-chromium alloy) is widely used for its high strength and outstanding corrosion resistance in a large temperature range (from cryogenic to very high temperatures). When Inconel is heated it forms a thick and stable oxide layer to protect itself from corrosions.
