Characterization and Identification of Metallic Materials

With the contents of this case, students discover various ores and metallic materials, identify and characterize them. The case contains 12 samples of different materials of the same volume that have undergone standardized hardness tests (Brinell and Vickers) and 5 ore samples.

Proposed Lab Topics

• Observation of samples and hardness test impressions
• Classification by color (dominant ore) and hardness
• Magnetism test, mass measurement to deduce density
• Documentary research: material, graphical representation, material price scale

Composition

• Set of 20 samples
• Precision balance, magnet, and graduated thread counter
• CD-ROM with educational and technical resources
