What Materials Engineers Do

Materials engineers develop, process, and test materials used to create a range of products, from computer chips and aircraft wings to golf clubs and snow skis. They work with metals, ceramics, semiconductors, plastics, composites, and other substances to create new materials that meet certain mechanical, electrical, and chemical requirements. They also develop new ways to use materials.


Materials engineers typically do the following:

Materials engineers create and study materials at an atomic level. They use computers to replicate the characteristics of materials and their components. They solve problems in a number of engineering fields, such as mechanical, chemical, electrical, civil, nuclear, and aerospace engineering.

Materials engineers may specialize in understanding specific types of materials. The following are types of materials engineers:

Ceramic engineers develop ceramic materials and the processes for making them into useful products, from high-temperature rocket nozzles to glass for LCD flat-panel displays.

Composites engineers work in developing materials with special, engineered properties for applications in aircraft, automobiles, and related products.

Metallurgical engineers specialize in metals, such as steel and aluminum, usually in alloyed form with additions of other elements to provide specific properties.

Plastics engineers work in developing and testing new plastics, known as polymers, for new applications.

Semiconductor processing engineers apply materials science and engineering principles to develop new microelectronic materials for computing and related applications.
