Ni20Cr

WOCO identifies this item as Ni20Cr nickel-chromium alloy powder, model / grade Ni20Cr.

The source size is 45–125 µm.

Some source size units are inconsistent with the powder designation. Confirm the required particle size and product form against the original record.

The source material field reads: Metco 5640NS.

Listed manufacturing route: Gas atomized.

Application & selection

Nickel-based coating powders cover several alloy systems with different corrosion, oxidation and wear roles. The supplied technical notes distinguish self-fluxing powders containing boron and silicon from non-self-fluxing systems such as nickel-chromium alloys.

Specify the actual alloy chemistry and intended spray or cladding route rather than substituting solely by a similar product name. Substrate compatibility, particle size and the required coating evaluation should be agreed for the application.

Details to confirm for this product

• Alloy composition and whether a self-fluxing system is required.
• Powder size, feed system and deposition method.
• Service environment, substrate and required coating tests.
