CZ132 is the old British Standard code for a dezincification resistant brass, and plenty of drawings and purchase orders still carry it. CZ132 DZR brass hollow rods are what you order when a hot stamped or machined water fitting has to start from stock that already has the hole through it. It is a leaded brass with a small arsenic addition, so it machines well and holds up against dezincification, but it is not a lead free brass.
Amardeep Steel Centre supplies CZ132 brass hollow rod from Mumbai, to export buyers and to workshops in India. Send the outside diameter, bore, length, temper and quantity on the enquiry page and you get back what can be shipped and when.

Application of Cz132 Dzr Brass Hollow Rods
CZ132 dezincification resistant brass hollow rods provide superior corrosion protection in water systems across several key applications:
- Water fittings: Fittings and connectors machined or hot stamped from hollow stock.
- Plumbers brass goods: Stopcocks, couplings and unions made in volume.
- Valves: Bodies, stems and trim for water and light duty service.
- Hot stamped parts: Components forged to shape and finished on a lathe.
- Hot forged parts: Fittings made from short cut lengths of rod.
- Mildly acidic or alkaline water: Components where ordinary brass would lose its zinc.
If the duty is seawater tube rather than rod, see our admiralty brass seamless tube and aluminium brass seamless tube ranges.

Frequently Asked Questions
1. What are CZ132 DZR brass hollow rods?
CZ132 is a dezincification resistant leaded arsenical brass, CuZn36Pb2As in EN naming, with about 36 per cent zinc, 1.7 to 2.8 per cent lead and a small arsenic addition. Hollow rod is stock with a bore through it, used for hot stamped and machined water fittings.
2. What does DZR mean?
DZR stands for dezincification resistant. In ordinary brass the zinc can leach out in some waters, leaving a weak, porous copper structure. The small arsenic addition in CZ132 slows that attack. It resists it better, but it does not make the brass immune, so tell us the water and the service.
3. Is CZ132 lead free?
No. CZ132 carries 1.7 to 2.8 per cent lead, which gives it good machining. It is not a lead free brass, and drinking water rules in many regions restrict leaded brass. Check the rule for the finished part, and ask us for a lead free grade if it applies. We make no compliance claim.
4. Is CZ132 the same as CW602N?
CZ132 is the old British Standard code for the brass now sold as CW602N, CuZn36Pb2As. The two are nearest matches, not identical: CZ132 asks for at least 0.08 per cent arsenic where EN allows 0.02. Check your drawing and name the grade on your order.
5. Is CZ132 the same as C35330?
They are the same family. C35330 is the UNS designation and CZ132 the British Standard code for a leaded arsenical DZR brass. The limits are written in different standards, so check them against your drawing before substituting, and use the code on your drawing on the purchase order.
6. Which standard covers CZ132 hollow rod?
CZ132 was written into the British Standards for brass rod and forgings, now largely replaced by the EN standards. Name the standard, delivery condition and tolerance on your order so tests match your drawing, and we confirm what applies to hollow rod.
