ASME SB111 C44300 Copper Alloy Tube O61 Cold Finished for Heat Exchanger Tubing
We are one of the largest manufacturers of stainless steel, duplex steel and alloy steel pipes in China. In our more than 20 years of development, we have won many customers all over the world, and Yuhong's products are highly appreciated by customers.
ASTM B111 ASME SB 111 C44300 Admiralty Brass is ideal for heat exchanger tubes. Normally this alloy is made to order to meet technical requirements. It is often used in oil and gas applications that also require its non-corrosive properties. C44300 and C68700 have good corrosion resistance. C44300 Admiralty Brass Seamless Tubing minimum tensile strength in 310Mpa, minimum yield strength in 105Mpa.
