Back-relief angle and bearing geometry are the best key factors in achieving rapid die finishing and the best die performance. In particular for the smallest bores, drawing and exit cones must be perfectly co-axial in order to achieve an accurate final geometry. With Cemented Carbide, one can manufacture tools and drawing nibs for the full range of wire drawing applications as High-carbon wire, Steel cord for rubber reinforcement, Bead wire, Welding wire, Stainless steel wire, Spring wire, etc.
 

A long experience and commitment to research and development enables Sandvik to offer a range of carbide grades to meet the drawing requirements for all applications.

H3F contains 3% cobalt and has a true sub-micron WC grain size. It is the benchmark for leading edge wet drawing of tire cord wire. Sandvik continually develops new grades and materials in order to offer improved performance to the industry.

Extremely fine grain sizes for the smallest holes

The progressive miniaturization of printed circuit board design requires ever smaller cutting tools. In order to meet performance requirements in terms of wear resistance, rigidity and toughness.

Today the trend is miniaturization: digital cameras, laptops and mobile phones become smaller and should include more features. To be able to meet this demand the PCB manufacturers have to drill more and smaller holes (less than 0,1 mm) carbide components and carbide tools can develop spindles with increasing rpm, to facilitate the use of very small drills and to increase productivity.

The grades for the PCB drill blanks industry have been developed through an extensive research program which utilizes an entirely new patented Cemented Carbide processing technology. This new process ensures that the Tungsten Carbide (WC) grain size is maintained within narrow limits and that the Cobalt (Co) binder phase is distributed in such a way as to fully maximize strength and toughness at all hardness levels.

Much of the equipment used in the Oil & Gas industry is subject to an aggressive environment that must not only resist erosion from high velocity fluids containing sand particles and other abrasive media, but it must also be resistant to corrosion damage. The combination of these two factors has caused this industry to migrate towards using more components that are made from Cemented Carbide. These components have natural properties that tend to resist such wear resistant mechanisms; however, Sandvik Hard Materials has dramatically improved the resistance to erosion and corrosion by focusing on the binder phase of grades used in this field. In order to improve the wear characteristics of the Cemented Carbide grades used specifically for choke valves in this industry, multi-binder (Ni, Cr, Mo, and Co) corrosion/erosion resistant materials were introduced.

Today, there are more than 100 choke control valves in service using these Cemented Carbide grades operating in subsea and other extreme environments. These materials have contributed to an improvement of up to 5 times service life when compared to conventional grades. Sandvik Hard Materials has now taken this performance increase to another level. Based on feedback gained from the field and the experiences of equipment design engineers working with these grades, Sandvik has carried out development work focused on improving material toughness and strength. Success has been achieved by carefully optimizing the relationship between wear (material hardness) and toughness for the multi-binder materials without any loss of resistance to corrosion or erosion.

Add value to your pumps and drilling devices and complete product range.

Wear resistance, toughness, corrosion resistance, and resistance to thermal shock are the key material properties required for long-lasting, all-perfect pump function.

The unique combination of all these material characteristics has made Cemented Carbide the most widely used material in carbide tools as pump seals and bearing in the sewage, mining and process sectors. Moreover, there is further potential to tailor Cemented Carbide for a vast range of environmental applications.

Sandvik grades offer a complete set of properties

■Excellent hardness / toughness compromise guarantees outstanding wear, erosion and shock resistance
■Robust surface
■Low friction coefficient and high mechanical strength
■High thermal conductivity and superior thermal resistance
■Resistant to handling and easy to assemble
■Support brazing, mechanical assembling, shrink fitting, press fitting and gluing
