some aluminum properties
Chrome moly tubing is a great high strength material for tubular steel frames. Great for race cars. Usually overkill for FIRST robots, but if you had a very-highly-stressed component it would be a good choice.
Some generic strength values for aluminum alloys (all values tensile yield strength):
2024-T4 aluminum 47,000 psi
6061-T6 aluminum 40,000 psi
7075-T6 aluminum 73,000 psi
3003-H14 aluminum 21,000 psi
