Alnico permanent magnet is a kind of motor magnet made of Alnico alloy, which is composed of Al,Ni,Co and other alloying elements. It has excellent magnetic properties, high energy, good temperature stability, and is widely used in generators, microphones, measuring instruments and other fields.
The material of Alnico permanent magnet is Alnico, and its shape can be customized according to customer requirements. It is a permanent magnet, and its maximum operating temperature is 550℃. Alnico5 and Alnico5 magnet are also popular names for this product.
Alnico permanent magnet has many advantages, such as good resistance to demagnetization, excellent temperature stability, high energy and good corrosion resistance. In addition, its magnetic properties are stable and reliable, and it can be used in a wide range of applications.
Characteristic of Both Cast and Sintered Alnico
Very temperature stable, great for high heat applications
Maximum working temperature 450-550°C
Does not lend itself to conventional machining (hard and brittle)
High residual induction and energy product compared to ceramic
material
Low coercive force compared to ceramic and rare earth materials
(more subject to demagnetization)
Most common grades of alnico are 5 and 8
Not suited for repelling or high friction applications

Alnico permanent magnets are shipped in protective packaging to prevent any damage that may occur during shipping. The packaging materials used can vary depending on the type of product being shipped. For example, if the magnets are shipped in bulk, they may be placed in cardboard boxes with padding to protect them from shock and vibration. If the magnets are being shipped individually, they may be placed in plastic bags or foam-lined boxes.
The packaging should also be labeled clearly with the product name, weight, and destination address. Proper labeling is important to ensure that the shipment reaches its correct destination. Additionally, the packaging should include any relevant safety information and handling instructions. This allows the shipping company to ensure that the magnets are handled properly and that they arrive safely.
