Sinter-Raw Material: Bars, Rods & Pre-Profiles

Since 2003, WELSCH has operated as a leading engineering authority in Tungsten Carbide metallurgy. We specialize in the forensic development of repair segments for extrusion heads, throat liners, guide rails, and machine beds. Beyond finished components, we provide our global partners with a strategic inventory of Sinter-Raw (Sinter-HIP) Tungsten Carbide profiles.

From selecting the ideal grade for your specific abrasive environment to providing precision-ground semi-finished parts, we manage the entire material lifecycle. Whether you require a single bespoke segment for an emergency repair or high-volume series production, we deliver Calculated Certainty with every milligram of material.

Our inventory includes high-density round rods designed for tool making and wear-protection, with diameters from 0.5 mm to 40 mm and standard lengths of 330 mm available for immediate dispatch. We provide in-house cutting to any specified length and precision grinding to your exact tolerance requirements. Our 92 HRA rods feature a Transverse Rupture Strength (TRS) of 4,000 N/mm², making them suitable for high-speed cutting tools and heavy-duty forming dies.

For machine-bed reinforcements, guide-rail liners, and stamping dies, we offer a massive selection of rectangular bars, plates, and blocks stocked in 330 mm lengths in Sinter-Raw condition with a calculated grinding allowance. Manufactured with a hardness of 89.5 HRA, a TRS of 3,800 N/mm², and a compressive strength of 5,600 N/mm², our fine-grained structure ensures superior results during Wire EDM, guaranteeing long-lasting cutting edges for stamping and punch-die applications.
