Familiar Sellers McMaster Carr, MakeItRingTargets, Alro Steel, SendCutSend

Material Description:

  • High strength, ultra wear resistant steel used in body armor and shooting targets
  • Hardened steel is difficult to machine, is typically only used for Waterjet parts
  • Typically used for weapons due to it's high strength, toughness, and relatively high hardness
  • Anecdotal experience from builders says that AR500 typically bends before it fractures

Aluminum 6061-T6

Type Aluminum Alloy
Modulus of Elasticity 10^7 psi
Shear Modulus 3800 ksi
Poisson's Ratio 0.33
Density 0.0984 lb/in^3
Ultimate Tensile Strength 45 ksi
Tensile Yield Strength 39 ksi
Fracture Toughness 26.4 ksi-in½
Brinell Hardness 93 HB
Rockwell Hardness B52
Elongation at Break 10%
Machinability (Vs. 1112 Steel) 270%
Familiar Sellers McMaster Carr, Midwest Steel Supply, SendCutSend

Material Description:

  • Lightweight aluminum alloy that has already undergone heat treatment to T6 temper which gives it its strength
  • Typically used for frame rails, plates, and armor for some bots
  • Tends to fail in bending before fracturing
  • Tends to "ablate" and may take gashes when hit directly by weapons
  • Easy to machine
