From atomic engineering of crystal grain boundaries to the customer-specific design of a wear part, Hyperion Materials & Technologies is dedicated to advancing the frontiers of cemented carbide (solid carbide or tungsten carbide (WC)) technology in order to meet our customers’ present and future needs. Every stage in the manufacturing of a cemented carbide component – from powder production to finishing – is crucial to ensuring optimum performance in your stamping tool blanks.

Below is an overview of the most common Hyperion Materials & Technologies cemented carbide grades suitable for typical stamping applications. For any other application, the Hyperion engineering team has the ability to evaluate the specific parameters of the stamping process and to recommend the tungsten carbide grade.

Ultrafine Grades

Hyperion Materials & Technologies has been manufacturing cemented carbide blanks for toolmakers in the integrated circuit (IC) industry since the 1980s when we introduced the ultrafine grades. These unique cemented carbides are best fit for stamping tool applications such as IC lead frames.

Today’s trend towards miniaturizations and higher strokes per minute further increases the demand on the stamping tool material.

Hyperion’s grade 12UF provides exceptional performance for sharp edge profiles through a combination of high wear resistance and high toughness.

 

Submicron Grades

When working with high pressure, the ability of the cemented carbide to withstand deformation is key to guaranteeing reliability of the stamping process. Additional challenges on the tool material include attaining sharp cutting edges after grinding and no chipping during use.

Hyperion Materials & Technologies’ submicron grades H15F, H10F, and H12F offer high hardness (HV30 from 1380 to 1600) in combination with high fracture toughness (K1C from 13 to 17). In addition, these grades exhibit high stiffness and good thermal conductivity that is critical for tool life performance.

Hyperion grades exhibit lifetimes double those of competitor's grades in electronic connector production.

 

Grade 12EF - New Generation of Submicron Grades

Processing stainless steel has been a challenge for different industries due to its tendency of work hardening and material adhesion during the stamping process. 

Our grade 12EF is blended in a unique way to overcome this challenge as Hyperion Materials & Technologies has optimized not only the tungsten carbide grain distribution but also improved the strength of  the binder phase in order to provide the best edge strength and also the ability to resist corrosion and oxidization.

Grade 12EF has shown performance superior to that of competitor grades in many of our key customers. 

In addition, grade 12EF is also designed for electrical discharge machining (EDM) processing to prevent damage from galvanic corrosion.

 

Medium and Medium Coarse Grades

Hyperion Materials & Technologies also provides solutions for processing soft materials such as pure copper and pure iron. Our grades H6N and H6P help to eliminate the tendency of adhesion to working material. 

The high toughness of these two grades makes them the perfect solution for some applications with thick materials.
