Self-Fluxing Nickel Alloy Powder 53-150 µm

Understanding Self-Fluxing Nickel Alloy Powders

Self-fluxing alloys contain elements like boron and silicon, which act as deoxidizers and fluxing agents during spraying. This creates a metallurgical bond with the prepared substrate, resulting in a coating with low porosity and high integrity. The nickel-rich matrix provides a solid foundation for wear and corrosion protection, often eliminating the need for a separate bond coat when applied correctly.

Particle Size and Process Compatibility

The 53-150 µm (micrometer) cut is a versatile workhorse range for thermal spray. It is fine enough to melt efficiently in high-velocity oxy-fuel (HVOF) and plasma jets, yet coarse enough to flow smoothly through powder feeders without clogging. This size distribution is also suitable for many flame spray powder setups. The result is a stable spray plume and a predictable coating build-up rate.

Typical Industrial Applications

Procurement teams and engineers select this powder for components that face a combination of wear, corrosion, or high-temperature oxidation. Common applications include:

• Shaft repair and dimensional restoration: Building up worn bearing seats, pump sleeves, and rotor journals.
• Valve components: Coating ball valve balls, gate valve seats, and stems for chemical and petrochemical service.
• Glass mould plungers: Protecting surfaces against hot glass contact and thermal cycling.
• General engineering parts: Protecting mixer blades, extruder screws, and mandrels from abrasive media.

Pack Options and Handling

We understand that job size dictates pack size. The powder is available in 5 kg tins for small batch work or trials, 10 kg tins for regular workshop use, and 25 kg pails for high-volume production or contract coating shops. Store containers sealed in a cool, dry environment to prevent moisture pickup, which can affect powder flow and cause porosity in the sprayed coating.
