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. 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 Verification
  • Coating Thickness and Composition
  • Contamination
  • Corrosion Analysis
  • Fiber Identification
  • Fractography
  • Macro Etching
  • Mechanical Testing
  • Microstructure Evaluation
  • Non-destructive inspection
  • Photo Documentation
  • Physical Testing
  • Quality control
  • Scanning Electron Microscopy (SEM)
  • Weld Evaluation

Examples of Recent Cases

  • Investigation of Weld Microstructures in Aluminum Lithium Alloys.
  • Failure of engine exhaust manifolds for Motor Homes.
  • Materials Selection for River Lock Gate Applications.
  • Analysis of Cracked Welded Assembly.
  • Analysis of Fractured Hydraulic Shaft.
  • Investigation of Fire Damage.
  • Dimensional Analysis of Printed Circuit Boards.
