DOM (Drawn Over Mandrel) Question

[Dave]

What alloy of DOM are most people using for suspension and cage components? Also, what alloy of steel plate for brackets, gussets, ect. is the most compatible? I know its a trade off between the strength and weight of the chromalloy and the weldability, formability, and machinability of the mild steel.

Thanks, Dave...

DOM tube is made to carbon steel spec ASTM A513- type 5. It is not an alloy but grade 1020 in wall thickness .134" and thinner. It is manufactured to spec, grade 1026, on wall thickness greater than .134"

I am new to fabrication so I let others give guidance on using material for brackets.
