DIN17660 CuZn20Al2 F39 Alloy Steel Seamless Tube is a special steel tube made from a specific alloy of steel. The alloy, known as CuZn20Al2, is a brass composed primarily of copper and zinc, with small amounts of aluminum added for strength and durability.
The DIN17660 in the name refers to the German industrial standard that the tubes follow. This standard ensures that the tubes meet specific specifications and quality standards.
The F39 designation is a specific grade within the DIN17660 standard. This grade is known for its excellent formability and good corrosion resistance, making it ideal for a variety of applications, including hot and cold water piping systems.
Seamless pipe is a pipe without welded seams, making it stronger and more durable than pipes with welded seams. This makes it ideal for high pressure applications.
In conclusion, DIN17660 CuZn20Al2 F39 Alloy Steel Seamless Tubes are high quality, durable steel tubes made from specific alloy steels in accordance with DIN17660 German Industrial Standards.
Characteristics of DIN17660 CuZn20Al2 F39
CuZn20 belongs to the German standard brass, the implementation of the standard DIN 17660-1983 CuZn20 ordinary brass higher strength, plasticity is also better, higher corrosion resistance, used as a thin-walled tube, wrinkled tube paper mesh and house building supplies.
