Tungsten Carbide Powders for Welding and Spraying: What You Should Know

Standard Particle Size Distributions

For welding and thermal spray applications, particle size plays a meaningful role in how a powder performs and how it feeds through equipment. Deloro’s standard range covers:

20 – 106 μm
45 – 125 μm
53 – 150 μm
63 – 180 μm

Further specifications and customized mixtures are available on request, which makes it straightforward to address non-standard process requirements.

A Versatile Portfolio for Demanding Applications

Deloro offers a broad range of tungsten carbide mixed powders, each combined with nickel-based hardfacing alloys from the established DelNite® family. What makes this portfolio particularly practical is its flexibility: composition and mixing ratios can be tailored to meet specific application requirements, so performance characteristics can be dialed in rather than compromised.

Whether the need is for a coating that resists abrasion, withstands elevated temperatures, or survives repeated mechanical loading, the combination of tungsten carbide with a metallic matrix delivers dense, highly resistant results across a wide range of industrial environments.

Key Physical Properties

Understanding the physical behavior of a powder before it enters your process saves time and reduces uncertainty. Here are the typical properties for these materials:

The hardness range after welding — 40 to 65 HRC — reflects the adaptability of the system. Different application environments call for different hardness levels, and the composition can be adjusted accordingly.

When to Consider These Materials

Tungsten carbide mixed powders are well suited for situations where standard materials fall short: components exposed to abrasive media, tooling that sees high contact stress, or surfaces that need to maintain dimensional integrity over extended service cycles. The thermal stability of the material also makes it relevant for processes running at elevated temperatures.

If you are currently evaluating wear protection or hardfacing options, comparing both the technical data and the practical handling characteristics of candidate materials early in the process tends to save effort downstream.
