Rockwell Hardness
Best For: Hard materials (HRC 20-70)
Advantages: Fast, direct reading, suitable for production
Limitations: Surface sensitive, limited to specific materials
Applications: Heat-treated steels, carbides, ceramics
Vickers Hardness
Best For: Wide range of materials (HV 10-3000+)
Advantages: Universal scale, microhardness capability
Limitations: Requires optical measurement, slower
Applications: Research, thin coatings, case studies
Brinell Hardness
Best For: Soft to medium hard materials (HB 1-650)
Advantages: Large impression, good for rough surfaces
Limitations: Large indentation, not for thin specimens
Applications: Castings, forgings, annealed materials
Shore Hardness
Best For: Elastomers, plastics, rubbers
Advantages: Portable, non-destructive, quick
Limitations: Limited to soft materials, temperature sensitive
Applications: Rubber components, gaskets, polymers
