Tungsten carbide strips, also known as carbide flat bars, are wear-resistant flat components made from cemented carbide, ideal for protecting wood and metal cutting tools from abrasion and impact. Rettek's grades like YG8 offer high toughness for woodworking shocks, while YG15 provides higher hardness for continuous metal cutting—select based on material and wear type for longer life via welded designs.

What Are Tungsten Carbide Strips and How Are They Made?
Tungsten carbide strips are flat bars of cemented carbide made from WC particles bonded with cobalt, formed via powder mixing, batching, pressing, and vacuum sintering for uniform density and superior wear resistance. Rettek controls the full in-house chain from raw alloy preparation to automated welding, ensuring consistent grain size for stable brazing in wood and metal cutting tools.
Why Do Tungsten Carbide Strips Excel in Wood and Metal Cutting Tools?
Tungsten carbide strips excel due to their wear resistance, corrosion resistance, and impact resistance from the WC-cobalt matrix, withstanding high-heat cutting without deformation. Rettek's unique welding technology provides higher strength than bonded types, delivering longer service life and reducing downtime in abrasive wood and metal cutting operations.
| Grade | Hardness (HRA) | Toughness | Best For |
|---|---|---|---|
| YG8 | 89–91 | High | Wood cutting, impact shocks |
| YG15 | 92–94 | Medium | Metal cutting, continuous wear |
| YG20 | 94–96 | Low | Precision metal grinding |
Table reflects standard grades; Rettek customizes via vacuum sintering for optimal fit in cutting applications.
Which Grade Should You Choose for Wood Cutting vs. Metalworking?
For wood cutting, choose YG8 for high impact toughness to handle shocks from knots and resin without chipping; Rettek's vacuum sintering ensures uniform grain size for reliable brazing. For metalworking, select YG15 or YG20 for superior hardness against edge dulling in ferrous and non-ferrous materials, with Rettek's welding for secure tool integration.
How Does Rettek's Manufacturing Process Ensure Superior Strip Performance?
Rettek's full in-house process—from raw material preparation, batching, pressing, and vacuum sintering with proprietary temperature control—yields uniform grain size and defect-free cemented carbide strips. Advanced automated welding and strict quality control enhance wear resistance, impact resistance, and corrosion resistance, proven in applications across 10+ countries.
