Frequently Asked Questions: Electronics Materials

How do soft magnetic alloys help extend smartphone battery life?

By using alloys with low coercivity and low core loss (like Hiperco® 50A), devices generate less internal heat during haptic or audio operation, preserving more energy for the battery.

What is the best material for shielding sensitive electronics from EMI?

HyMu 80 is the gold standard for EMI shielding due to its extremely high initial and maximum permeability, which effectively redirects electromagnetic flux away from sensitive sensors.

Why is "Kovar" used in electronic sensors?

Kovar is designed to have a thermal expansion coefficient that matches most hard glasses. This ensures that when the metal and glass are fused together, they expand and contract at the same rate, preventing cracks in the hermetic seal.

How does Hiperco® enable smaller haptic engines?

Hiperco® alloys have higher magnetic saturation than standard iron or steel. This means you can get more motor force out of a smaller volume of material, allowing for thinner device designs.
