Notes:

Particle Size: Supply in two grain sizes: 0.83mm～25.4mm 90% MIN and 0.83mm～12.7mm 90% MIN.
Appearance: Light grey sponge-like metal, clean surface, free from visible impurities. For Grade 5, defects should not exceed 0.1% of batch quantity.
포장: Pack in zinc-plated iron barrels with plastic film lining, sealed with a large diameter lid. After packaging, barrels must be evacuated and filled with argon.
