Brass Tube

CW614N (CuZn39Pb3, Ms58) brass tube. Because it machines easily it is also known as “hollow rod”; it is used for bushes, bearings and turned parts as well as decorative and fitting parts.

Grade and sizes

CuZn39Pb3 · CW614N

MS58

A free-machining brass containing about 58 % copper, 39 % zinc and 3 % lead. The lead makes the chips short and brittle, so the alloy machines cleanly at high cutting speeds with a good surface finish. It is well suited to hot forging, while its cold formability is limited. It is one of the most widely used brasses for turned and CNC-machined parts, fasteners, fittings and valve components.

INTERNATIONAL EQUIVALENTS

EN CW614N · DIN 2.0401 · UNS C38500 · BS CZ121
Tube standard: EN 12168

OUTSIDE DIAMETER (OD): Ø3–100 mm
LENGTH: 3000–3200 mm (full lengths)
CUTTING: Sold in full lengths. For orders specifying lengths and quantities, tubes are cut if the wall thickness is suitable for sawing; very thin-walled tubes are not cut.

Enter either the wall thickness or the inside diameter to calculate.

Order terms: Sold in full lengths; for orders specifying lengths and quantities, tubes are cut if the wall thickness allows. This is a theoretical weight; we invoice on the actual weight as weighed.

Frequently asked questions

How should I specify the tube size?

Tube size can be given as outside diameter × wall thickness × length (for example Ø20 × 2 × 3000 mm) or as outside diameter × inside diameter × length. In the weight calculator you choose one of these two options; either the wall thickness or the inside diameter has to be entered.

What are the designations for MS58?

MS58: CuZn39Pb3, EN CW614N, DIN 2.0401, UNS C38500, BS CZ121. Any of these designations can be used in your enquiry; we will match the correct material.

Why can the invoiced weight differ from the calculated weight?

The calculator gives the theoretical weight. The actual weight varies with dimensional tolerances and cutting allowance; we invoice on the actual weight as weighed.

What information should I send for a quote?

We only need the size (outside diameter × wall thickness × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
