Overview: This unit is assessed internally via a controlled assignment in which the learners must analyse materials for a product and produce a research
report. The main feature of this unit is the selection of an engineered product for analysis. The learners should be encouraged and guided to select a
suitable product for study, which contains a wide range of materials. Information could be communicated in the form of a presentation to a group of
learners; this could be electronically using the current OCR standard.
This unit will enable learners to find out about the structure, properties and classification of engineering materials. Learners will:

Apply their understanding of the properties of materials, design, cost and availability to correctly specify materials for different engineering applications.

Develop an understanding of the key features and applications of new, modern and smart materials.

Investigate what causes materials to deteriorate and how this can be prevented.

Learn how to use mathematical and scientific principles (Level 3 Unit F563 Mathematical techniques and applications for engineers and Unit F564
Scientific principles and applications for engineers) within engineering metallurgy. A feature of the unit is the analysis of an engineered product, which
results in learners identifying materials used in its manufacture and providing evidence of the properties, which led to their selection.
The practical work and the selection of materials for certain applications may contribute to other units such as Unit F557 Applications of computer aided
designing and Unit F562 Innovative design and enterprise
There are many opportunities for Learners to develop and demonstrate their PLT’s in this unit.
