Tungsten Carbide Saw Tips for Pre-Soldered Copper
Key Advantages
✅ Pre-Soldered Copper Base: Eliminates flux pre-treatment, achieving 99.9% weld joint integrity.
✅ Ultra-Hard Cutting Edge: HRA 90–92 hardness withstands abrasive wood fibers and bone fragments.
✅ Hygienic & Non-Stick: Mirror-polished surface (Ra ≤0.2μm) prevents meat residue buildup.
✅ Custom Geometry: Multiple tooth profiles (ATB, TCG, FT) for clean cuts in soft/hard materials.
Technical Specifications
Material Composition

-
Pre-Soldered Layer: 0.3–0.5mm pure copper (Cu-ETP C11000), melt point 1083°C.
Standard Sizes & Tolerances
| Tooth Type | Width (mm) | Thickness (mm) | Height (mm) | Copper Thickness (mm) |
|---|---|---|---|---|
| Wood Band Saw | 3.0–12.0 | 1.5–3.0 | 4.0–8.0 | 0.3 ±0.05 |
| Meat Cutting | 2.0–6.0 | 1.0–2.5 | 3.0–5.0 | 0.4 ±0.05 |
| Specialty Blades | Custom 1–20 | Custom 0.5–5.0 | Custom 2–15 | 0.2–0.8 (adjustable) |
Note:
-
All dimensions comply with ANSI B94.50 and ISO 4875 standards.
-
Custom tooth angles (10°–35°) and serration patterns available.
Applications
1. Wood Processing
-
Band Saw Blades: Cut hardwood, plywood, and MDF with chip-free edges.
-
Circular Saws: Tips for ripping, cross-cutting, and veneer trimming.
2. Food Industry
-
Meat & Bone Saws: FDA-compliant blades for beef, pork, and poultry processing.
-
Frozen Food Cutters: Maintain sharpness at -40°C operating temperatures.
3. Composite Materials
-
Carbon Fiber Cutting: Anti-delamination tooth geometry.
-
Plastic & Rubber Saws: Non-stick coating options (DLC/TiN).
Welding & Installation Guide
-
Blade Preparation: Clean base metal (65Mn/75Cr1 steel) with acetone.
-
Positioning: Align tips using laser-guided fixtures (gap <0.1mm).
-
Induction Heating: 800–900°C for 5–8 seconds to activate copper bonding.
-
Cooling: Air-cool naturally; avoid quenching to prevent stress cracks.
Result: Shear strength ≥300 MPa, 2x higher than manual flux soldering.
