These round tubes are made from grade 101 copper which is highly conductive and commercially pure. They are easy to solder, braze, weld, and form. They are often manufactured into automotive parts and components, conductors, or other parts that require electrical or thermal conductivity.

Grade 122 round tubes are easier to machine, form, weld, and braze than grade 110 copper tubes. They resist corrosion and are often used for heavy forming applications and manufactured into pipes, tubing, and other plumbing parts and components.
