ASTM B111 C44300 2.0470 Copper Alloy Seamless Tube Heat Exchangers
The specification B111 covers seamless tube and ferrule stock of copper and various copper alloys up to 79 mm， inclusive， in diameter， for use in surface condensers， evaporators， and heat exchangers.
Admirality brass is an alloy that is zinc and copper-based and is having arsenic and zinc in a small amount. These tubes are renowned for the excellent features of high resistance to corrosion at the polluted river water and in clean seawater and also at slow moving and stagnant water. Admirality brass tubes are used widely in many critical applications because of durability， flexibility， heat resistivity， longevity etc.
ASTM B111 Brass Tubes are ideal for heat exchanger. Normally made in order to meet engineering requirements， you will find this alloy often used in oil and gas applications that also require its non corrosive properties.
