Core material composition differences
1. Aluminum oxide copper adopts a composite structure of aluminum oxide ceramic particles and copper matrix, featuring both high thermal conductivity and structural stability.

2. Chromium zirconium copper is a copper-based alloy material, achieving solid solution strengthening by adding chromium (0.5-1.2%) and zirconium (0.03-0.3%).

Comparison of key preparation processes
1. Aluminum oxide copper is prepared using powder metallurgy technology, achieving uniform distribution of ceramic phase and metal phase through high-temperature sintering.

2. Chromium zirconium copper is fabricated through vacuum melting and casting technology, combined with aging heat treatment to obtain the desired microstructure.
