Material

Important aspects when considering material:

  • Weight
  • Strength
  • Durability

It is important that our device has a low density while having high tensile and fatigue strength along with a high fracture toughness. The material that fits this material criteria the best is aluminum alloy where it is one of the lightest metals available and has substantial strength and durability according to its tensile and fatigue strengths and fracture toughness.
