A technical examination of grain sizing, cobalt distribution, and sinter-HIP densification in harsh tribological operating conditions.
Microstructure & Grain Control
The anti-wear characteristics of tungsten carbide strips depend primarily on the average grain size of tungsten monocarbide (WC) particles and the cobalt binder percentage. APEX utilizes proprietary ball-milling algorithms to generate ultrafine and submicron structural matrices that balance high abrasion resistance with mechanical fracture toughness.
- Submicron WC grains (0.4–0.8 µm) for sliding abrasive contact
- Optimized cobalt phases avoiding localized pools or micro-voids
- Strict magnetic saturation (MS) monitoring preventing carbon deficits
Low-Pressure Sinter-HIP Densification
Traditional vacuum sintering leaves microporosities that compromise edge strength under extreme shear. APEX strips are processed via 100-bar high-pressure Sinter-HIP technology, driving density to metallurgical perfection (>99.9% theoretical density) and eliminating internal micro-flaws.
- Transverse Rupture Strength (TRS) increased by 20% to 35%
- Elimination of A- and B-type porosities per ISO 4505 standards
- Superior edge retention preventing spalling under impact
Thermal & Chemical Stabilization
Wear strips frequently encounter severe thermodynamic gradients and acidic attack. With a low coefficient of thermal expansion (4.5–6.0 × 10⁻⁶/K) and extreme Young's modulus (up to 650 GPa), our grades maintain critical contact geometry without warping or softening at elevated temperatures.
- High resistance to thermal fatigue during interrupted cuts
- Corrosion-resistant grades with Ni/Cr binder options
- Stable operation in aggressive timber resins and slurry environments

Frequently Asked Questions for Wear Strip Buyers
Clear, direct answers regarding tolerances, brazing procedures, MOQ, and material selection.
What surface finishes and grinding tolerances are available for carbide strips?
We supply strips in as-sintered (un-ground) state with standard tolerances (±0.5 mm to ±0.8 mm) or surface ground to high precision with thickness tolerances down to ±0.005 mm and parallelism within 0.01 mm, suitable for direct mounting without secondary EDM grinding.
How do you handle brazing stress when bonding carbide strips to steel bodies?
Due to the difference in thermal expansion between cemented carbide and steel, we recommend copper-silver tri-metal sandwich shims (Ag-Cu-Ag) for strips exceeding 150 mm in length. This absorbs shear stresses during cooling, preventing post-braze micro-cracking.
What is the standard Minimum Order Quantity (MOQ) and sample lead time?
For standard metric and imperial strip profiles, the MOQ starts from 1 piece to allow physical trial and laboratory validation. Custom preformed or profiled strips require tooling initialization with pilot batches delivered within 10 to 14 days.
Can you provide bevel angles and mounting holes on sintered carbide strips?
Yes. Utilizing multi-axis CNC profile grinders and wire EDM equipment, we provide custom bevels, clearance angles, countersunk screw holes, and pre-machined radius edges according to customer engineering drawings.
