- Manufacturing Process:
- Cast AlNiCo: This type is made by pouring a molten alloy into a mold and then allowing it to cool and solidify. This process results in a material with good magnetic properties and shape versatility.
- Sintered AlNiCo: Sintering involves compacting fine AlNiCo powder in a mold under high pressure and then heating it to just below its melting point. This process fuses the powder particles together, creating a solid material. Sintering generally results in a denser and more uniform structure compared to casting.
- Properties:
- Cast AlNiCo: Generally has higher properties than sintered AlNiCo. Cast AlNiCo tends to have a lower density and may show some dimensional variation due to the casting process.
- Sintered AlNiCo: Generally has the ability to make smaller and more complex products. Sintered AlNiCo also tends to have a higher density and better dimensional accuracy due to the nature of the sintering process.
- Applications:
- Cast AlNiCo: Suitable for applications where complex shapes are required or magnetic strength is not a primary consideration. Commonly used in instruments, sensors, and small motors.
- Sintered AlNiCo: Suitable for applications that require complex shapes or less demanding magnetic strength, such as sensors, relays, and certain types of motors, where high stability and strength are critical.
- Cost and Availability:
- Cast AlNiCo: Generally more economical to produce in small quantities and offers more flexibility in design due to the casting process.
- Sintered AlNiCo: Usually more expensive due to the higher manufacturing costs associated with the powder processing and sintering steps. However, it provides superior magnetic properties and consistency.
