Today, we are answering a frequently asked question at Copper and Brass Sales – what is the difference between a pipe, tube, and hollow bar?
Tube
Manufacturing Method: Tubes are created by using slit coils of metal and putting it through a tube mill, a series of dies. Once the required shape, round, square or rectangle, has been formed, the edges are welded together.
Measurement: Tubing size is specified by OD and the wall thickness (WT)Shapes: Round, Square, Rectangle
Materials Available from Copper and Brass Sales: Round: Aluminum Alloys 1100, 2024, 3003, 6061, 6063, 6262. Stainless Steel Alloy 304,
Hollow Bar
Manufacturing Method: Hollow Bars can be manufactured either by putting a drill through a solid bar or by centrifugal casting, where a mold is rotated at fast speeds while the molten metal is added.
Measurement: Hollow bar is measured by the outer diameter and the inner diameter.
Shapes: Round
Materials Available from Copper and Brass Sales: Copper C17200, Brass C44300, Bronze C86300, C93200, C95400
