2J4 4J28 Nickel based Pipe
2J4 belongs to the iron-cobalt-vanadium series hysteresis alloy. This series of alloys is suitable for making high-efficiency hysteresis motor rotors. The operating temperature is high, and the alloy will not cause a reduction in magnetic properties in the range of +150~-140℃. Among various types of hysteresis alloys, 2J4 is the one that has been used for a longer time and has a larger dosage. After years of exploration and practice, the technology and production processes of our hysteresis alloy 2J4, 2J9, and 2J10 series products have become more perfect.
4J28 is a 4J28 precision alloy with abnormal thermal expansion characteristics, also known as 4J28 expansion alloy. It is widely used in the electronic industry, precision measurement tools, precision instruments, cryogenic engineering and other fields. Generally, metals and alloys expand after heating, and the expansion and temperature increase linearly. However, the bending point temperature of some alloy thermal expansion curves is much lower than the normal thermal expansion coefficient at the bending point. This phenomenon is called abnormal thermal expansion characteristics. . 4J28 expansion alloy is divided into low expansion alloy and fixed expansion alloy, the latter is also called sealing alloy.
