Kovar 4J29 Nickel Iron Alloy Machining Part Description
Kovar alloy, also known as 4J29 alloy, is mainly composed of iron, nickel and cobalt. Its chemical composition is controlled within a narrow range to facilitate deep drawing, stamping and CNC machining, and to ensure accurate and uniform thermal expansion properties. Kovar 4J29 Nickel Iron Alloy Machining Part is mainly used for the sealing of electric vacuum components such as transmitter tube, oscillator tube, igniter tube, magnetron, transistor, relay, integrated circuit, chassis, shell, bracket, etc. It can also be widely used in semiconductor, aerospace, national defense industry. Electronic and electrical, chemical equipment, automobile manufacturing and instrumentation and other fields.
Kovar Nickel Iron Alloy Features
1. Thermal expansion: The low coefficient of thermal expansion of Kovar alloy makes its performance similar to borosilicate glass or ceramics, thus ensuring the stability and reliability of the sealing parts.
2. Mechanical properties : Kovar alloy has high strength and toughness, can withstand a variety of harsh working environment.
3. good processing properties and plasticity , can be processed through a variety of ways, such as forging, rolling, drawing, etc., convenient for subsequent application and assembly
4. Excellent electrical and thermal conductivity, which can meet the needs of electronic equipment for power transmission and heat dissipation
5. Provides consistent magnetism for electronic applications
We have extensive experience and advanced equipment in the field of Kovar processing. We employ the latest CNC machine tools and precision machining technologies, including milling, turning, drilling, grinding and wire cutting, to ensure that we can meet the requirements of a wide range of complex parts and meet strict quality standards.
