DIN17660 CuZn20Al2 F39， UNS C68700 Seamless Aluminums Brass Tube For Heat Exchanger
DIN17660 CuZn20Al2 F39 seamless copper alloy aluminums brass tube is a specific type of alloy tube that is made from a specific alloy of steel. This alloy， known as CuZn20Al2， is a type of brass that is primarily composed of copper and zinc， with a small amount of aluminum added for additional strength and durability.
Brass is a mixture of copper and zinc with a homogeneous material structure. It is characterised by higher strength than copper， a high torsional and bending stability as well as a high corrosion resistance. Brass is widely used in various industrial applications such as machine equipment， power plant， construction， chemical industry.
