High performance copper tungsten rod supplier

Copper tungsten rod:

Diameter from 0.5 mm to 120 mm.

Length from 3 mm to 1000 mm.

Tolerance: h5 and h6.

1. Made by infiltration process, high density, stable thermal‑electrical performance; COA test report available per batch. Differentiate from low‑cost direct‑sintered material.

2. Superior arc‑erosion resistance, low material consumption under arcing conditions, extend service life of components.

3. Tunable CTE matches semiconductor ceramic substrates, minimizes thermal‑stress risk & solder joint delamination.

4. Custom sizes & CNC‑machining available: ground plate, cutting, drilling, OEM drawings acceptable.

5. Compliant with ASTM B702 & RWMA industry standards, equivalent to Elkonite grades.

6. Good performance under vacuum condition, low out‑gassing for vacuum interrupter & RF microwave components.
