Product Brief Introduction:
Glid Copper refers to a family of Copper-based metal matrix composite (MMC) alloys mixed primarily with aluminum oxide ceramics particles.
The addition of small amounts of aluminum oxide has minuscule effects on the performance of the copper at room temperature (such as a small decrease in thermal and electrical conductivity), but greatly increases the copper’s resistance to thermal softening and enhances high elevated temperature strength. Glid has higher hardness value (HV > 125) and tensile strength (>350 MPa), compared to OFC’s HV40 and 250 Mpa.
The addition of aluminum oxide also increases the thermal conductivity or electrical conductivity is required while also maintaining strength at elevated temperatures or radiation levels. |

Additional materials and elements can be added if lower thermal expansion is required, or higher
room temperature and elevated temperature strengths. The hardness can also be increased.
A composite material of Glid AL-60 and 10% Niobium provides high strength and high conductivity.
The hardness is comparable to many copper-beryllium and copper-tungsten alloys, while the
electrical conductivity is comparable to RWMA Class 2 all. |
