The material of manganese copper alloy is mainly composed of alloy elements such as manganese, copper, nickel, etc. It has the characteristics of high resistivity, low temperature coefficient (low temperature drift), and no parasitic inductance, and is a key material for making alloy resistance components. Widely used in alloy resistance components.
The material characteristics of manganese copper alloy are as follows:
1. Melting temperature range: 1350-1400 ℃
2. Specific heat capacity: 455J (KG. ℃)
3. Density: 8.0g/cm ³
4. Magnetism: No (no parasitic inductance)
5. Tensile strength: Mpa ≥ 390
Application characteristics of manganese copper alloy products:
1. High electrical resistivity: It can be made into high-precision alloy resistors and potentiometers
2. Low temperature coefficient of manganese copper alloy: able to maintain relatively stable resistance values over a wide temperature range
3. Manganese copper alloy has good machinability: it can be improved through cold working and heat treatment
4. Manganese copper alloy has good corrosion resistance
Manganese copper alloy can be made into high-precision alloy resistors based on the above materials, especially for resistors with ultra-low resistance values. Its material characteristics have no inductance value, and it is more widely used in frequency conversion products with high inductance requirements.
Alloy resistors have very strict requirements for raw materials, whether it is the product itself or external influences. There are also extremely high requirements for the use and carrier of the product, which can be combined with ceramic basic to make metal foil alloy resistors or metal film alloy resistors. Currently, the main brand manufacturers that can produce ceramic substrates are: Walter, SUSUMU, EVER OHMS, etc.
