DIN17660 CuZn20Al2 F39, UNS C68700 Seamless Aluminums Brass Tube For Heat Exchanger
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.
