Materials Engineer
Develop and select the metals, polymers, ceramics, and composites that every engineered product is made from.
Materials engineers study the structure, properties, and performance of materials — metals, alloys, ceramics, polymers, composites, and semiconductors — and apply that knowledge to develop better products and processes. They work in aerospace, automotive, electronics, biomedical devices, construction, energy, and nanotechnology. In Sri Lanka, materials engineers work in manufacturing, ceramic tile production, rubber processing (natural rubber is a key export), construction materials, and import substitution industries. Globally, advanced materials for EVs, batteries, aerospace, and medical implants are boom areas.
What a Materials Engineer does daily
- Analyse the microstructure and properties of materials
- Select appropriate materials for engineering applications
