ASTM B111 C44300 Aluminum Brass Tubes: High-Performance Seawater Corrosion Resistance

ASTM B111 C44300 (UNS C44300) is a lead-free aluminum brass alloy specifically engineered for marine and industrial applications requiring exceptional resistance to dezincification, erosion, and biofouling. These seamless tubes are ideal for condensers, heat exchangers, and desalination systems operating in seawater or brackish environments.

Key Features:

Material Type: CuZn21Al1As (Aluminum Brass with Arsenic addition)
Standards: ASTM B111, ASME SB111, EN 12451
Temperature Range: -40°C to 150°C (-40°F to 302°F)
Certifications: NACE MR0175, ISO 9001:2015

C44300 Chemical Composition (ASTM B111)

Element	Min (%)	Max (%)	Role in Alloy
Copper (Cu)	70.0	73.0	Base metal for corrosion resistance
Zinc (Zn)	26.7	29.3	Enhances strength and workability
Arsenic (As)	0.02	0.10	Prevents dezincification in seawater
Aluminum (Al)	-	0.02	Improves oxide layer adhesion
Iron (Fe)	-	0.06	Controlled impurity
Lead (Pb)	-	0.07	Maintains machinability

Industrial Applications of C44300 Tubes

Industry	Typical Uses	Performance Advantage
Marine Engineering	Shipboard condensers, desalination plant heat exchangers	Resists biofouling and saltwater pitting (0.05 mm/year corrosion rate)
Power Generation	Steam turbine cooling systems, nuclear plant tubing	Withstands high-velocity seawater (up to 3 m/s)
Oil & Gas	Offshore platform cooling loops, LNG heat exchangers	Compatible with chlorinated fluids (up to 5 ppm Cl⁻)
Chemical Processing	Acidic fluid transfer systems, evaporators	Stable in pH 6-8.5 environments

Why Choose ASTM B111 C44300 Tubes?

Superior Lifespan: 20-30 years in seawater applications (vs. 10-15 years for Admiralty Brass).
Cost-Efficiency: 15-20% lower lifecycle cost compared to titanium alternatives.
Manufacturing Flexibility: Available as seamless/ERW tubes, U-bends, or custom lengths (1-12 meters).
Testing Guarantee: 100% eddy current tested (ASTM E309), hydrostatic pressure tested (ASTM B88).
