Reducing structural weight is one of the major ways to reduce carbon emissions and improve aircraft performance. Lighter and/or stronger materials allow greater range and speed and may also contribute to reducing operational costs. AMG has innovated a number of specialty alloys and coatings used to help reduce weight and improve the operational performance of aircraft.
Through extensive research beginning in the mid 1990s, AMG developed titanium aluminides (TiAl). Initial applications for this high strength, low weight material included components for Formula 1 race cars (valves) and have evolved into alloys for aerospace applications. Titanium aluminide alloys offer superior high temperature performance with low weight for turbine blades and are as strong as nickel based alloys, but at only half the weight. These alloys will allow for a favorable engine design, reduced fuel consumption and less hazardous emissions, thus reducing the impact on the environment.
Below is a representative aerospace jet engine. AMG produces the specialty materials listed for each part of the jet engine.
