Materials Engineering Group
About the Materials Engineering Group
The group has a diverse range of interests covering many topics within the field of materials, including ferrous and non-ferrous metallurgy, fracture and failure mechanisms, ceramics, polymers and composites. Experimental, theoretical and computational methods are used to study processing-properties-structure-performance interrelationships in each of the classes of materials. It has a history of providing a service both in research, failure analysis and routine testing to the materials industry in New Zealand and is continuing to develop this role.

Failure Analysis Consultation
The Materials Group's team of engineers and technicians combines design, industrial process and material testing experience to accurately determine the root cause of product and process problems. Whatever the material, chances are we've tested it and understand its properties.
Aerospace Materials - Automotive Materials - Aluminum - Brasses - Carbon Steels - Castings - Coatings - Composites - Corrosion Resistant Steels - CVD and PVD Coatings - Elastomers - Electronic Components - Plating - Polymers - Powder Metals - Tool Steels.
The list below shows that The Materials Group can go well beyond physical testing. We test the total environment and condition of metal parts and sub assemblies and have the equipment and the expertise to move to the microstructure level to complete the analysis process.
- Chemical composition
- Coating thickness and composition
- Materials durability and degradation
- Corrosion testing and analysis
- Mechanical testing
- Microstructural characterisation of metals, polymers and composites
- Non-destructive inspection
- Photo documentation
- Quality control
- Scanning electron microscopy (SEM)
- Weld evaluation
- Thermal and chemical analysis of plastics and composites
- Thermal expansion coefficient of materials
- Density measurements
