    best aluminum grade for cutting

    as i discovered with stainless, some grades cut better than others. In general the sheet stock grade (321 i believe?) left a pretty nasty edge compared to 304.

    i have a job coming up in aluminum and i haven't cut that yet. What grade would you recommend? its going to be 1/8" sheeting.

    choices being

    1100
    5052 (says easy to weld according to McMaster)
    6061
