Glidcop

Glidcop is a family of copper-based metal matrix composite (MMC) alloys mixed primarily with small amounts of aluminum oxide ceramic particles. It is a trademark of North American Höganäs. The name is sometimes written GlidCop or GLIDCOP.

The aluminum oxide particles block dislocation creep, which retards recrystallization and prevents grain growth; thus preserving the metal's strength at high temperatures. They also protect the metal against radiation damage. On the other hand, they exclude the possibly of heat treatment or hot working of the worked parts.
