Is this for 6061 aluminum?
This uses a standard density of 2.7 g/cm³, which is very close for most aluminum alloys including 6061 (2.7 g/cm³) and 7075 (2.81 g/cm³).
Total volume: 1000.0 cm³. Aluminum is lightweight, about 1/3 the weight of steel.
Scrap aluminum is worth ~$0.50-$0.80/lb. New material cost varies widely but expect $3-$8/lb depending on form and alloy.
At 2.700 kg, this piece is manageable for one person.
