Processing
For high class SS it goes though mirroring and mechanical polishing
And for chrome plated or titanium plated after shaping it we elcetrically coat it with chrome
Application
ASTM weights can be used as reference standard in calibrating other weights and appropriate for calibrating high-precision analytical and high-precision toploading balances, laboratory students, and rough industrial weighing.
Advantage
With more than ten years of experience combined with special skill acquired through years of weight polishing guarantee the consistent high quality for all customer demands.
ASTM weights are designed to resist dust offering a long term stability.
