Copper Alloy TubesAdmiralty Brass & Aluminium Brass Tubes
Seamless Admiralty brass and aluminium brass tubes for heat exchangers, condensers, marine & shipbuilding, chemical & process industries and architectural uses.
Overview
High-performance copper alloy tubes
BK Industries manufactures Admiralty brass tubes (CuZn28Sn1) and aluminium brass tubes at our plant in Palghar, Maharashtra, near Mumbai, for marine and industrial buyers across India.
For applications where standard brass is not enough, BK Industries manufactures seamless copper alloy tubes — Admiralty brass (CuZn28Sn1) for heat exchangers, condensers and marine service, and aluminium brass for marine, chemical & process and architectural applications.
Both are made in our 1/4" to 4" OD size range with 0.25–5 mm wall, drawn, annealed, straightened and tested in-house. For 70/30 brass, see Brass Tubes.
- Admiralty brass (CuZn28Sn1) — excellent corrosion resistance in seawater
- Aluminium brass — superior corrosion resistance, good high-temperature strength
- Seamless, high-precision tubes
- Sizes 1/4" to 4" OD (6.35–101.6 mm), 0.25–5 mm wall
- Soft (annealed), half-hard and hard tempers — as per client requirements
- Straight lengths up to 18 ft (approx. 5.5 m), or cut-to-length pieces
- In-house hardness testing and hydrostatic pressure testing
