Tuf-Cote® - Tungsten Carbide Hardfacing

 

 Tufcote    Saint-Gobain Coating-Solutions manufactures and markets hard-facing Flexicords made of tungsten carbide particles mixed within a self fluxing nickel matrix. Our Flexicords are used as a brazing electrode welded thanks to a brazing torch.Our Flexicords are sold under several trade marks such as TUF-COTE®, TUF-COTE® HR2.

 

TUF-COTE® provides abrasion resistant coatings for many markets and applications such as oil drilling, ore mining, power generation, dredging, waste treatment, foundries, steel making, bricks & tiles, cement, wood industries, agriculture, palm oil, sugar cane…

 

We listen to our customers in order to understand the type of wear involved in their process, the technical solution and the return of invest that our customers are expecting from our hardfacing solutions. Every wear problem does not necessarily involve the same solution and we carefully study each situation to offer the optimum product and application.

 

Our range of TUF-COTE® is periodically improved in order to improve the versatility and the ease of use and to provide the highest level of abrasion resistance. TUF-COTE® ropes are available with a larger core wire and TUF-COTE® can be produced with or without organic skin as well. If our range of products is not perfectly suitable for a specific problem of abrasion, we can design and produce a customized TUF-COTE® in a close co-development with our customers.

 

The benefits of our range of TUF-COTE® are:
• High mass percentage of Tungsten carbides allowing to improve the life-time and the durability of the coated tools.
• When brazing, it is easier to get the great pool of molten metal, improving consequently the weld-ability of TUF COTE®.
• The improvement of the weld-ability makes possible to get smoother and more accurate coatings. The deposition rate of TUF-COTE® is also improved, thus higher productivity.
• During the brazing operation, the new TUF-COTE® is easier to handle and has less breakage occurrence.
