Following Egide's decision to discontinue the Santier thermal management line, engineering teams that previously relied on these components can rely on Spectra-Mat for continuity — same WCu and MoCu material families, same application focus, U.S. manufacturing.
BUILT FOR HIGH-PERFORMANCE THERMAL MANAGEMENT
Spectra-Mat specializes in controlled expansion thermal management materials based on tungsten copper and molybdenum copper. Its proprietary copper infiltration process in a highly homogeneous sintered tungsten matrix supports equal thermal conductivity in all x-y-z directions and stable CTE behavior across demanding operating temperatures.

For build-to-print components, the fastest way to identify a Spectra-Mat equivalent is by material composition and application. The table below maps the most common WCu and MoCu compositions to typical applications and key technical parameters.
| Material | Compositions | Typical Applications | Key Technical Parameters |
|---|---|---|---|
| WCu Tungsten-Copper | W90/Cu10 W85/Cu15 | RF & microwave packages · GaN / GaAs / MMIC thermal bases · Heat sinks for high-power devices | [TO BE VALIDATED] CTE values (ppm/K) · thermal conductivity (W/m·K) · plating options (Ni/Au, Ni/Ag) |
| MoCu Molybdenum-Copper | Mo85/Cu15 ★ Mo70/Cu30 | RF packaging · Power electronics · Semiconductor packaging · Heat spreaders for power devices | [TO BE VALIDATED] CTE values · thermal conductivity · machining tolerances · plating options |
| Custom Tailored ratios | Custom W/Cu Custom Mo/Cu | Custom thermal expansion matching to specific device substrates and assembly requirements | [TO BE VALIDATED] Range of custom compositions · minimum order quantity · lead time |
★ Mo85/Cu15 — widely used composition for RF packages
