AlNiCo Magnets
· Wide range of internationally compatible alloys
· High field strengths at medium prices.
· Excellent temperature characteristics with a reversible coefficient of induction.
· Highest operating temperature range of any permanent magnet material.
· Compatible with most painting or plating systems (including nickel and copper)
· Wide range of complex shapes and sizes available.
· Ease of magnetization.
· Ease of calibrating magnets or assemblies for precise levels of performance.
· Mature of product technology.
· Lower initial tooling cost when compared with most permanent magnet materials.
· Can be silver soldered to other circuit components.
· Low field strengths required for saturation makes magnetizing after assembly. |
