1. The difference between 4J50 and 4J29.
Both 4J50 and 4J29 belong to the iron-nickel alloy family, but they differ in metal composition and properties. 4J50 is an alloy with a higher permeability, which has a higher permeability than permalloy, and has lower coercivity and loss. This alloy is mainly used to make electronic devices such as high-sensitivity magnetic amplifiers, transformers, and leakage protectors.
In contrast, 4J29 is an alloy with a lower coefficient of expansion, and its coefficient of thermal expansion is close to that of glass and ceramic materials. This alloy is mainly used to make precision electronic devices, optical devices, communication equipment, etc., to achieve high-precision alignment and fixation.
Second, the application of 4J50.
Because 4J50 has high permeability and low coercivity, it is widely used in the manufacture of electronic devices such as high-sensitivity magnetic amplifiers, transformers, and leakage protectors. The higher permeability of this alloy allows for greater magnetic induction at a smaller magnetic field, resulting in higher sensitivity and smaller volume of electronic devices.
In addition, 4J50 is also used in the manufacture of magnetic components such as solenoid valves, magnetic locks, magnetic separators, and equipment such as magnetic resonance imaging instruments in the medical field.
3. Application of 4J29.
Because 4J29 has a low coefficient of thermal expansion, it is widely used in the manufacture of precision electronic devices, optical devices, communication equipment and other fields. The coefficient of thermal expansion of this alloy is close to that of glass and ceramic materials, which can effectively reduce the alignment error and size change caused by temperature changes, and improve the stability and reliability of the device.
In the field of electronic devices, 4J29 is used to make electronic alignment sheets, thin film resistors, hybrid circuit substrates, etc., to improve the accuracy and stability of electronic devices. In the field of optical devices, 4J29 is used to manufacture optical lenses, optical fiber connectors, optical fiber splitters, etc., to ensure the alignment accuracy and stability of optical devices. In the field of communication equipment, 4J29 is used to manufacture communication antennas, microwave devices, RF modules, etc., to improve the signal quality and stability of communication equipment.
In addition, 4J29 is also used in the manufacture of parts for high-precision measuring equipment such as precision instruments, sensors, and measuring instruments, as well as precision parts and structural parts in the aerospace field.
Fourth, summary. 4J50 and 4J29 are two different iron-nickel alloy materials, and their differences lie in metal composition and properties. 4J50 has high permeability and low coercivity, and is mainly used in the manufacture of high-sensitivity magnetic amplifiers, transformers, leakage protectors and other electronic devices; 4J29 has a low coefficient of thermal expansion and is mainly used in the manufacture of precision electronic devices, optical devices, communication equipment and other fields. Understanding the characteristics and application areas of these two alloy materials will help you better select the right materials to meet the needs of different fields.
