Product Overview
High-Performance ASTM B111 C44300 Admiralty Brass Tubes for Heat Transfer Applications.
ASTM B111 C44300 Admiralty Brass Tube is a seamless copper alloy tube widely used in condensers, heat exchangers, evaporators and other heat transfer equipment. The alloy contains approximately 70% copper, 29% zinc and a small addition of tin, providing improved resistance to dezincification and corrosion in fresh water, mildly saline water and industrial cooling systems.
Manufactured in accordance with ASTM B111, C44300 tubes offer excellent thermal conductivity, good cold-working properties and reliable mechanical strength for pressure-containing heat transfer applications.

Frequently Asked Questions(FAQ)
It is mainly used for heat exchangers, condensers, evaporators and cooling systems requiring efficient heat transfer and good corrosion resistance.
The tin addition improves resistance to dezincification, making C44300 more suitable for cooling water and condenser service than standard brass grades.
C44300 performs well in fresh water and mildly saline water. For high-velocity seawater or more aggressive marine environments, copper-nickel alloys such as C70600 or C71500 are generally preferred due to their superior seawater corrosion resistance.
Yes. Outside diameter, wall thickness, length and temper can be manufactured according to project requirements.
