Chromium
Chromium targets produced by Achemetal Tungsten & Molybdenum Co., Ltd. include chromium plane targets and chromium-niobium rotating targets.
The purity respectively includes: Cr99.5%,Cr99.7%,Cr99.8%,Cr99.9%,Cr99.95%。
Features of targets manufactured by Achemetal:
1. Due to the adoption of a hot isostatic pressing process, the product features high density, good compactness and uniform crystal grains.
2. Higher machining property
3. Relative density of targets: over 99%, relative density of alloy: over 97%; grain size: less than 50um; thermal resistance of films: below 5%; welded rate with back plates: over 98%, film uniformity after target film formation: over 95%
