Haptic feedback requires precise motor responses to simulate a range of tactile feedback. Carpenter Electrification’s alloy material solutions provide high induction and permeability for improved haptic designs and enhanced user experience.


Sensitive electronic parts and components need to be shielded from electromagnetic interference (EMI) for phones, wearables, and headsets to work properly. Soft magnetic alloys are used to form thin stampings that suppress, attenuate and mitigate disruptive magnetic fields.

Precise Output Up to 200 Degrees Celsius
Stable Productive Over Time
Very Low Thermal EMF

Battery management systems monitor the current and voltage to determine charge levels in electric vehicles. The resistors in the BMS must maintain a consistent resistance value at different operating temperatures to provide reliable feedback to the system. Carpenter Electrification offers Evanohm® R, a low-temperature coefficient of resistance alloy for accurate readout of battery charge.
