High Altitude, High Quality
MTI – A Trusted Leader in Aerospace Engineering
From an aircraft’s first takeoff to its final landing, the parts that help lift a plane into flight need to be able to withstand the high stress and vigorous demands of air travel. That’s why all mainstream aerospace engine manufacturers have an MTI-built friction welder on their production floors. For decades, we’ve worked with high-profile aerospace companies to develop new, innovative parts and solutions that are stronger, lighter and resistant to high temperatures. With increased joint strength and the ability to join dissimilar metals, friction welding can help make good parts great and strong parts even stronger.
