This article will provide you with comprehensive answers! As a professional manufacturer, we not only supply high-precision tungsten carbide materials but are also committed to helping customers match the best processing solutions.
I. How to choose high-quality cemented carbide rods?
Cemented carbide rods are the core materials for manufacturing cutting tools, molds, and wear-resistant parts. The selection should focus on the following points:
- Material Certification ：
Choose to comply with ISO or ASTM standards integral cemented carbide tungsten steel rods to ensure that the cobalt content ( 6%-15% ) and grain size ( 0.5-2μm ) are suitable for your working conditions.
- Dimensional Accuracy ：
Diameter tolerance should reach ±0.01mm (such as Ø6mm and above tungsten steel alloy rods to avoid excessive subsequent processing allowance.
- Surface Treatment ：
Fine grinding or polishing surface ( Ra≤0.4μm ) can reduce tool wear, especially suitable for precision turning and milling cutter shank processing.
II. Five Core Advantages of Tungsten Steel Alloy
Whether it is cemented carbide rolls 、 wire drawing dies , or integral tungsten steel rods , its excellent performance comes from the efficient combination of tungsten carbide ( WC ) and cobalt ( Co ):
- Ultra-high hardness ： HRA 88-93 , surpassing high-speed steel 3 times, excellent wear resistance.
- High-temperature oxidation resistance : Remains stable at 1000°C , suitable for high-speed cutting and hot rolling scenarios.
- Corrosion resistance : Resistant to acid and alkali corrosion, extending the life of wire drawing dies in wet processing.
- Compressive strength ：6000-7000MPa , withstands high-frequency impact of rolls without deformation.
- Electrical and thermal conductivity : Superior to ceramic materials, avoiding local overheating during processing.
III. Application Comparison of Cemented Carbide Rolls, Wire Drawing Dies and Tungsten Steel Rods
Core Function | Applicable Scenarios | Material Properties | |
|---|---|---|---|
cemented carbide rolls | Metal wire / Rod material rolling deformation | Continuous rolling of copper rods and stainless steel wires | High cobalt content ( 10%-15% ) improves toughness |
Cemented carbide wire drawing dies | Reducing the diameter of metal wires and surface polishing | Copper, aluminum, steel wire drawing ( Φ0.1-10mm ) | Ultra-fine grain ( 0.5μm ) ensures aperture accuracy |
integral tungsten steel rods | Cutting tool matrix, stamping die | Drill bits, milling cutters, die inserts manufacturing | Balanced hardness and anti-collapse (cobalt content 8%-10% ) |
