Material Product Data Sheet

Magnesia-Stabilized Zirconium Oxide Thermal Spray Powders
Thermal Spray Powder Products: Metco 210NS-1, Metco 210NS-1-G, Metco 210, Amdry 333

1 Introduction
Fused and Crushed
Coatings of magnesia stabilized zirconia powders have
low thermal conductivity and a high melting point, mak-
ing them excellent high temperature thermal barriers.
Coatings with Metco 210NS-1 are resistant to particle
erosion in high temperatures and resist wetting of mol-
ten zinc, iron, steel, copper and aluminum.

Metco 210 and Amdry 333 are fused and crushed pow-
ders. Metco 210NS-1 and Metco 210NS-1-G are manu-
factured using Sulzer Metco’s HOSP™ process, which
makes spherical powders that are superior to the angu-
lar fused and crushed powders. The free-flowing spheri-
Agglomerated & HOSP™
cal shape of HOSP particles results in high purity and
excellent flow during material feed. The consistent pow-
der particle size results in more uniform particle melting
during spraying.

2.4 Key Selection Criteria

• Choose the product that meets the required customer and better coating consistency than Metco 210 and
material specifications. Amdry 333.

• Amdry 333 and Metco 210 are both fused and • Metco 210NS-1 and Metco 210NS-1-G have slightly
crushed products. Choose Amdry 333 when OEM different particle size distributions to meet different
certifications are required. OEM specifications. This may also affect spray param-
eters and deposit efficiencies.
• Metco 210NS-1 and Metco 210NS-1-G are HOSP™
powders, which result in higher deposit efficiencies
