HZH-2.3 High-Thermal-Conductivity Aluminum Alloy

Die-Casting for Motor Housings and Drive Units

A motor manufacturer previously used ADC12 alloy for the housings of their 5kW motors and the heat-dissipation modules of the drive units. Following consultations with us, they switched to our high-thermal-conductivity aluminum alloy for these components. This resulted in an average reduction of 7°C in the steady-state temperature of the motor housing and a 5°C reduction for the drive unit, effectively extending the mean time between failures (MTBF).
