Williams Advanced Materials
SIL-X 

Superior jitter and reflectivity characteristics when compared to current silver alloys. What is Sil-R™? Sil-R™ is a proprietary (US and International patent pending) silver-based alloy developed by Williams Advanced Materials for the reflective (L1) and semi-reflective (L0) layers in DVD discs. Qualified by WAMO and currently in production, Sil-X™ offers superior jitter and reflectivity characteristics after environmental testing as compared to current silver alloys.
