UNS C44300 Admiralty Brass Tube PDF
Products Description
The legacy of Admiralty Brass UNS C44300 is rooted in solving a critical engineering challenge. Early brass condenser tubes failed from dezincification a process where zinc leached from the alloy in seawater leaving behind a weak porous copper structure. The innovation was adding approximately 1% tin to the copper-zinc formula. This modification essentially improved performance by creating a stable protective surface film to inhibit dezincification. The result is an alloy with an optimal balance of thermal conductivity mechanical strength and corrosion resistance.
Core Advantages
1. Marine Corrosion Benchmark: Dezincification depth <0.1 mm/year (ASTM G48 seawater), service life >15 years.
2. Heat Exchange Efficiency: Condenser tube heat transfer coefficient ≥5200 W/m²·K, 30% better than stainless steel.
3. Forming Adaptability: Cold bending radius ≥2× wall thickness; compatible with Ag/Cu-P brazing.
4. Environmental Safety: As ≤0.06%, complies with EU REACH industrial exemption.
