How can one distinguish between magnesium and aluminum alloys physically?

Click For Summary
SUMMARY

To distinguish between magnesium alloys and aluminum alloys, one can utilize chemical analysis techniques such as X-ray or emission spectroscopy to determine the precise alloy composition. Physical characteristics to consider include yield strength, ultimate strength, strength-to-weight ratio, elongation, thermal conductivity, corrosion behavior, and toughness. These factors are critical in identifying the specific alloy type and its suitability for various applications.

PREREQUISITES
  • Understanding of X-ray spectroscopy and emission spectroscopy
  • Knowledge of material properties such as yield strength and ultimate strength
  • Familiarity with thermal conductivity and corrosion behavior of metals
  • Basic concepts of alloy composition and classification
NEXT STEPS
  • Research X-ray spectroscopy techniques for alloy analysis
  • Study the mechanical properties of magnesium and aluminum alloys
  • Explore methods for measuring thermal conductivity in metals
  • Investigate corrosion testing methods for different alloys
USEFUL FOR

Materials scientists, metallurgists, engineers, and anyone involved in the selection and testing of metal alloys for industrial applications.

How would one go about distingushing between magnesium alloys and aluminum alloys (physical characteristics)?
 
Engineering news on Phys.org
One would do a chemical analysis - e.g. X-ray or emission spectroscopy to determine precise alloy composition.

Other than that, one can look at strength (yield and ultimate), strength-to-weight ratio, elongation, thermal conductivity, corrosion behavior, toughness, . . .
