Good corrosion resistance

The strongest of the non-Rare Earth Magnets is also excellent for high temperature applications. While quite hard and brittle, they can be machined using special tools and equipment to close tolerances.
Two different manufacturing processes are used; magnets are either Cast or Sintered, and a wide variety of shapes and sizes are readily available.
A Sintered AlNiCo magnet is structurally stronger than Cast AlNiCo and generally provides parts with closer tolerances prior to machining.

Alnico Cylindric Retaining Magnet Sizes & Shapes
The ability to form and machine this material provides a wide range of potiential sizes and shapes as the photograph above illustrates. So, although many standard sizes and shapes are available, this is an excellent magnet when a specific size, shape or configuration is required.
Applications requiring close size tolerances often use these magnets since they can be machined and ground to size.

Alnico Deep Pot Magnet
Alnico pot magnet is a deep cylindrical permanent magnet which are assembled in a mild steel pot using spacers like Aluminum or Copper. The working temperature of this magnet is around 250° C. Outer surface except pole can be either painted or coated with Zinc, Nickel or Chrome. Assembly of the magnet and correct spacing are achieved by the use force-fitted aluminium ring . While working above 200°C, precaution must be taken of possible mechanical loosening through expansion and contraction of the component parts.

Heat is another strength for alnico magnets.
Their maximum working temperature is 540 degrees C (1004 degrees F).
The Curie Temperature for alnico magnets is a blistering 860C (1580F).
Hot temperatures are not going to affect these magnets much!

Details of Alnico Deep Pot Magnets (Zinc Plated)

The Alnico deep pot magnet is a deep pot magnet ideal for use in the highest temperature applications. The zinc plated mild steel body combined with the alnico’s natural good corrosion resistance provides the alnico deep pot magnet with good overall corrosion resistance and excellent magnetic performance with most oils.

The design includes a brass spacer between the zinc plated mild steel and the Alnico 5 magnet to retain the alnico magnet in position. The pole face, where the clamping occurs, is ground to a smooth finish. The rear of the alnico deep pot magnet is blind ended (no thread or tapped hole).
