AR500 Steel
| Type | Carbon Steel |
| Modulus of Elasticity | 30 x 10^6 psi |
| Poisson's Ratio | 0.29 |
| Density | 0.29 lb/in^3 |
| Ultimate Tensile Strength | 225 ksi |
| Tensile Yield Strength | 200 ksi |
| Brinell Hardness | 450 HB |
| Rockwell Hardness | C48 |
| Elongation at Break | 12% |
| 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, pulleys, 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
