Description

We provide raw magnets made out of hard ferrite, neodymium, samarium-cobalt (SmCo) and AlNico (AINiCo), respectively in cylinder and cube shapes.
Various sizes and types available. We look forward to receiving your request.
hard ferrite

Cost/benefits: |
low cost |
Adhesion: |
low adhesion |
Operation temperature: |
up to 200°C |
Mechanical impact: |
excellent mechanical stability |
Chemcial resistance: |
high chemical resistance, as is the case for all ceramic materials |
Toxicity: |
practically environmentally neutral, non-toxic. |
Subsequent processing: |
only possible via grinding |
Neodym (NdFeB)

Cost/benefits: |
medium price range |
Adhesion: |
offers the greatest adhesive strength |
Operation temperature: |
up to 80°C (high-quality magnets up to 200°C) |
Mechanical impact: |
less brittle than SmCo magnets, but just as sensitive to breakage from impact or blows |
Chemical resistance: |
high proportion of pure iron means that it is not resistant to moisture, acids or alkalis. Galvanization or organic sealing of the surface is required for permanent protection. |
Toxicity: |
Inhaling grinding dust must be avoided, no direct influences are known. |
Subsequent processing: |
only possible via grinding and eroding |
Samarium-Cobalt (SmCo)

Cost/benefits: |
high cost |
Adhesion: |
relatively high adhesive strength |
Operation temperature: |
up to 250°C |
Mechancial impact: |
very brittle |
Chemical resistance |
substances that contain freely moveable hydrogen ions are not suitable for SmCo magnets. These include all types of acids and alkalis, sodium nitrate solutions (at higher temperatures) and also hydrogen gas. |
Toxicity: |
Inhaling grinding dust must be avoided, no direct influences are known. |
Subsequent processing: |
only possible via grinding and eroding |
AlNico (AINiCo)

Cost/benefits: |
high cost |
Adhesion: |
medium adhesion |
Operation temperature: |
up to 450°C |
Mechanical impact: |
hard, slightly lower mechanical stability than hard ferrite, crystalline structure |
Chemcial resistance |
chemical resistance similar to high-alloy steel, not resistant in inorganic acids, sea water or strong alkali solutions. The material is not corroded by organic solvents, alcohols, oils or petrol. |
Toxicity: |
environmentally neutral, non-toxic. Persons who react to nickel may experience the same side effects as with other materials containing nickel. |
Subsequent processing: |
only possible via grinding and eroding |
