C44300 Admiralty Brass is the industry standard for applications involving brackish water, seawater, and harsh fresh-water environments. The inclusion of roughly 1% Tin (Sn) and a controlled amount of Arsenic (As) prevents dezincification and inhibits stress corrosion cracking, making it significantly more durable than standard brass alloys.
Key Benefits & Features:
Superior Corrosion Resistance: Inhibited with Arsenic to eliminate dezincification in marine and industrial environments.
Excellent Thermal Conductivity: Engineered for maximum heat dissipation in heavy-duty cooling applications.
High Workability: Easily formed, expanded, and manipulated during heat exchanger fabrication.
Technical Specifications & Chemical Composition
Our C44300 tubes undergo rigorous quality checks, including eddy current testing and hydrostatic testing, to comply with ASTM B111 / ASME SB111 standards.

Frequently Asked Questions (FAQ)
What is the role of Arsenic in C44300 Admiralty Brass?
Arsenic acts as a highly effective inhibitor against dezincification. When brass is exposed to corrosive waters, the zinc can dissolve, leaving a weak, porous copper structure. The trace addition of Arsenic in C44300 locks the alloy structure together, preventing this failure mode.
What specifications and sizes do you offer?
We supply C44300 tubes in standard Outer Diameters (OD) ranging from 6mm to 50mm, with wall thicknesses spanning 0.5mm to 3.0mm. Custom straight lengths can be cut precisely to your project's engineering blueprints.
Do you provide test certifications for bulk procurement?
Yes. Every shipment is accompanied by Mill Test Certificates (MTC) according to EN 10204 3.1, including chemical composition analysis, physical dimensions, and non-destructive testing reports.
