Product Portfolio

We offer a variety of standard specification hardmetal powders for use in most metal additive manufacturing, thermal spraying and metal injection moulding equipment.

What set us apart, however, is our ability and capacity to collaborate with our customers to develop customised powders for targeted applications. The key benefits of AM technologies lie in the design freedom and process flexiblity that AM can offer. Why stop there when we can design the endless possibilities of microstructures for tailored mechanical, thermal and corrosition properties.

PowderLoop can support our customers to design new materials composition and subsequently produce custom powders to your requirements.

Tungsten Carbide Base Powder

Outstanding product characteristics make tungsten carbides suitable for demanding requirements of e.g. steel, paper, oil and gas applications. With correct amount of binder metal, it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armour-piercing rounds, other tools and instruments. For hardfacing applications, the coating properties (e.g. hardness and wear resistance) depend primarily on the grain size and volume fraction of the tungsten carbide particles used.

Chromium Carbide Base Powder

Chrome carbide is an excellent alternative to tungsten carbide, depending on operating conditions. While chrome carbide has lower wear resistance than tungsten carbide, coating containing a nickel/chrome binder chemistry exhibits better heat resistance and oxidation resistance characteristics at higher temperatures and under corrosive or oxidising conditions.

Self-fluxing Alloy Powder

Self-fluxing powders are self-deoxidised and self-slag when melting. The low-melting point eutectic of self-fluxing nickel alloys combines with the surface oxides to form borosilicates, promote wetting on the substrate. These alloy powders have good abrasive and metal-to-metal wear resistance. The addition of WC-Co will improve hardness.

Quality Assurance

All the powders we supply are subjected to strict quality control. We have carefully selected our material suppliers to make sure only high quality ingredients are used in our production process.

Every stage of the production process, from weighting and milling, to sieving and analysis, are carried out to our high standard operating procedures to ensure batch-to-batch quality and consistency.

Sample powders are assessed in accordance to International Standards to ensure quality of our hardmetal powders meeting your expectations. These include particle size analysis (ASTM B214/ISO-4497), flowability (ASTM B212/ISO-4490), aparent density and chemical composition analyses.

Our Powder Production

Hardmetal are typically manufactured using a spray drying technology, a low temperature process that prevent carbide from decomposition. Unlike gas atomisation used in the metal powder production, no melting is involved during spray drying.

Sub-micron input materials are fed, in carrier fluid, through an atomisation nozzle into the drying chamber. Fine droplets are dried almost instantly which larger particles fall into the collecting container, whereas finer particles are collected in a cyclone separator. Each particle is an agglomeration of hundreds of the tiny input materials.

Our agglomerated and sintered powders are spray dried and classified into the 15-45µm size range, ideal for most AM and HVOF processes.
