70 RB Typical Hardness Pure Zinc Wire 1200 psi 1.6mm / 2.0mm Diameter
PRODUCT OVERVIEW
Pure Zinc is a 99.99% pure zinc wire specifically designed for spraying in arc spray and flame spray systems. It produces a dense, well bonded coating that is ideal for corrosion protection of steel, electrical conductivity, applications and mold making. It is also used as a bond coat when spraying metals onto non-metallic substrates.
TYPICAL DEPOSIT CHARACTERISTICS:
Þ Typical Hardness: 70 RB
Þ Bond Strength: 1200 psi
Þ Deposit Rate: 24 lbs/hr/100A
Þ Deposit Efficiency 70%
Þ Wire Coverage: 0.9 oz/ft2 / mil
Þ Surface Texture * Variable
Þ Machinability Good
* Depends on air pressure used
SURFACE PREPARATION
Surface should be clean, white metal, with no oxides (rust), dirt, grease, or oil on the surface to be coated. Note: It is best not to handle surfaces after cleaning.
Recommended method of preparation is to grit blast with 24 mesh aluminum oxide, rough grind, or rough machine in a lathe.
