Properties of 351 Stainless Steel
Properties of 7075 (Air Craft) Aluminum

• Density 8.03 g/cc
• UTS 485 MPa
• YTS 205 MPa

• Density 2.81 g/cc
• UTS 505 Mpa
• YTS 435 Mpa
• Fatigue Strength 150 MPa (21800 psi)

In addition to the higher strength and reduced
weight of the Aluminum frame, it is easily
machined and relatively resistant to fatigue.

Monte Carlo Simulation

• Simulated Production tolerances
• Parameters used length, width, thickness,
  Modulus of Elasticity of the brace support.
• After the simulation data was analyzed and
  simulation results reflected the original mean
  and standard deviations.
