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
