Engineered for mission-critical wear parts, cutting tools, and surface engineering, our sintered tungsten carbide grits and particles deliver uncompromising performance where conventional abrasives fail. Sourced exclusively from 100% virgin raw materials and precision-sintered under controlled atmosphere, each batch meets strict ASTM B294 (hardness), B578 (microstructure), and E11 (particle size distribution) standards — ensuring consistent density, uniform grain structure, and zero porosity.
Ideal for global OEMs and Tier-1 suppliers in mining, oil & gas, construction equipment, and hardfacing industries, these YG6C and YG8C grade particles offer superior bonding integrity, minimal thermal distortion during welding or thermal spray, and extended service life under abrasive, impact, and high-temperature conditions.
Consistently exceeds 89.5 HRA per ASTM B294 — enabling exceptional resistance to micro-cutting, gouging, and plastic deformation in aggressive wear environments.
Retains structural integrity and hardness up to 800°C; oxidation-resistant surface layer forms at ≤500°C in ambient air — critical for hot-working tooling and furnace components.
Tight particle size distribution across 0.35–9mm mesh range (ASTM E11 certified); eliminates batch-to-batch variability for repeatable thermal spray deposition and PTA cladding.

We support full OEM/ODM collaboration — from custom particle size profiling and binder optimization to proprietary packaging, traceability labeling (batch ID, heat number), and application-specific technical guidance.
Yes. YG6C and YG8C grades are widely used in HVOF and plasma spray due to their balanced hardness-toughness profile, low oxide content (<0.15%), and excellent sphericity (>90% after classification). We supply pre-classified spherical particles upon request.
Standard lead time is 12–15 working days after sample approval and deposit confirmation. For urgent orders (≤500 kg), we offer expedited production in 7 working days — subject to raw material availability.
Yes. Each batch includes a signed ASTM-compliant test report covering hardness (HRA), microstructure analysis (grain size, porosity), and particle size distribution (ASTM E11 sieve analysis).
Yes. We provide free 50 g samples of standard YG6C/YG8C grits (0.5–1.0 mm mesh) for evaluation. Custom-grade samples available at nominal cost (refundable against first order).
