A Wolfram carbide hard metal coating is either carried out with self-fluxing powder flame spraying  according to DIN EN ISO 14920:1999 or with HVOF (high speed flame spraying).

In some applications a strong line strain would destroy the sprayed coating in which an egg shell effect would occur. For example, hard metal drums cannot be replaced by softer metals by a flame sprayed coating with Wolfram carbide as the pressures are too high for that sprayed coating alone.

All of our inserts and cutters are manufactured to our specifications using high grade carbide with micro-grain size of 0.7-1.0 µm. These micro-grains are combined with a 10% binder that yields a hardness of 1650 HV10. They are then finely ground to a razor cutting edge with toughness and durability for long-lasting, smooth cutting in the most dense hardwoods.

Oct 25, 2017 — I have been using HSS and brazed carbide tooling. I can't honestly say I know all my geometries, speeds, hp formulas and so on.

Oct 30, 2023 — Hammer-Drill & carbide tipped drill bit is far faster than rotation only- especially on the paving bricks. Go slowly and use moderate pressure.

Feb 17, 2020 — Only eight metals are considered precious metals in the world: gold, silver, platinum, palladium, osmium, iridium, ruthenium, and rhodium.

The Wolfram carbide is supplied to us by the powder suppliers in broken or gas atomised condition with test certificate. Many drawings carry the mentions e.g. 'hard metal coating' or "Tungsten Carbide", both do not mean anything else than a coating with Wolfram-Tungsten carbide.

We have used Wolfram carbide for coating in many industries for decades. Mixing, engineering and sealing techniques are but a few of our areas of expertise.

We carry out qualified and flexible Wolfram carbide hard metal coatings for you. We will of course be happy to give you free advice.

Grand Sea offer round, square, radius, and diamond shaped carbide inserts and cutters that fit many of the commercial woodturning lathes and tools.

In both coating methods the Wolfram/Tungsten carbide powder is sprayed on the surface of the work element as plastic and clings onto the previously sprayed base component.

This Wolfram carbide coating makes it possible to choose a cheap basic component for the product itself for many application purposes, which is then fitted with a hard metal coating and thus obtains the required hardness.  In that case an expensive complete hard metal copy can be dispensed with.
