FAQ

A: Please let us know your specific application (cutting/wear/impact), workpiece material, equipment parameters, and current problems. We will provide free grade recommendations.

A: These are grade designations in China’s national standard for cemented carbide:

• YG (tungsten-cobalt): Suitable for cast iron, non-ferrous metals, wear parts
• YT (tungsten-titanium-cobalt): Suitable for steel cutting
• YW (tungsten-titanium-tantalum-cobalt): General purpose, suitable for stainless steel, alloy steel

A: Of course. Please let us know your workpiece material, working conditions (cutting/wear/impact), current problems, etc. Our engineers will recommend suitable grades and specifications.

A: Yes. We can provide product specifications, material certificates, dimensional drawings, CAD models, etc. Please let us know what you need.

A: Red hardness refers to the ability of a tool material to maintain hardness and cutting ability at high temperatures (such as those generated during cutting). Tungsten carbide has much better red hardness than HSS.

A: Virgin material is produced directly from ores or raw chemicals, with high purity and stable performance. Recycled material is reprocessed from scrap cemented carbide, with lower cost but higher impurity content and certain performance differences.

A: HIP stands for Hot Isostatic Pressing, a sintering process under high temperature and high pressure, which can significantly reduce internal porosity and improve density and mechanical properties.

A: For conventional applications, our product performance is comparable to brands like Sandvik、Kennametal, but with better pricing. 

A: Tungsten carbide is extremely hard after sintering and cannot be machined with conventional tools. It is typically ground with diamond wheels or processed with EDM (electrical discharge machining) for complex shapes.

A: Tungsten carbide itself does not rust, but products with cobalt binder may show surface oxidation in extremely corrosive environments. For corrosive conditions, we can provide special grades or coatings.

A: Diameter ranges from 0.3mm to 50mm, length up to 1000mm. Sizes beyond this range can be customized according to your drawings.

A: Common grades include YG8, YG10, YG15, YG20, YL10.2, YL10.2A, etc. For example, YL10.2 is suitable for stainless steel and titanium alloy processing, while YG series are suitable for conventional materials like cast iron and steel.

A: Tungsten carbide strips feature excellent high-temperature resistance and wear resistance. They have good corrosion resistance in conventional industrial environments. They are stable for long-term continuous work.

A: They have excellent red hardness, high hardness, good wear resistance and chemical stability, suitable for long-term use under high temperature and wear conditions.

A: Each batch of plates undergoes non-destructive ultrasonic flaw detection, ensuring no sand holes or pores, with reliable quality.

A: The plates are sintered by HIP (Hot Isostatic Press) sintering furnace, greatly reducing porosity and enhancing compactness. The blanks are formed by isostatic pressing machine, resulting in more uniform density and effectively preventing pressing defects.

A: Our plates undergo stress release treatment, effectively avoiding cracks during cutting and forming processes.

A: Also known as YD cemented carbide welding rods, YD cemented carbide brazing rods, YD composite alloy rods, etc.

A: Hardness > 160HB. Particle sizes available: 1-3mm, 3-5mm, 5-7mm, 6-8mm, 8-10mm, 9-12mm. Weight: 450g/pc.

A: They are mainly used for surfacing on fishing tools and drilling bits in the oil and gas industry, greatly improving wear life.

A: Made of YG type cemented carbide raw material through mechanical crushing.

A: Hardness > 160HB. Particle size range: 10 mesh to 80 mesh, can also be customized according to customer requirements.

A: Used for metal surface spraying and workpiece surfacing to improve wear-resistant layer performance

A: We have various ball molds and can produce fine grinding balls with diameters from 0.3mm to 60mm.

A: Sintered by vacuum integrated furnace or high-pressure sintering furnace, with good performance, 100% free of pores and sand holes.

A: Yes. Non-standard sizes can be produced according to customer’s drawings and requirements.

A: They are mainly used in oilfield TC bearings and coal mine drill wear blocks, as well as cone drills, diamond drills and stabilizers

A: The estimated lead time will be about 15-25 working days when out of stock.

A: Various types and dimensions of button bits tips are available for selection.

A: Both raw material and recycled material can be supplied according to customer’s quality requirements. Price is negotiable for very large demand.

A: Estimated lead time will be 15-25 days if no stock

A: Spherical buttons feature a full round dome top, providing the best impact resistance and crack resistance, ideal for hard, high-abrasive rock such as granite and basalt. Conical buttons have sharp tips for faster penetration, suitable for medium and soft rock layers. Ballistic buttons adopt a streamlined bullet shape, balancing drilling speed and toughness, perfect for mixed and fractured rock formations.

A:For most conventional hard rock drilling projects, YG8 is the universal grade with balanced hardness and impact toughness. YG6/YG6X offers higher wear resistance for fine drilling and highly abrasive formations. YG11 with higher cobalt content provides stronger toughness, suitable for high-impact, heavy-duty mining conditions to prevent cracking.

A: The main causes include grade mismatch for geological conditions, improper pressing interference fit (too loose causes falling out, too tight causes cracking), eccentric drilling vibration, and continuous operation with severely worn flat buttons. Over 90% of button failures are caused by unreasonable usage rather than product quality problems.

A: Slightly worn carbide buttons can be reconditioned and re-pressed for secondary use. Buttons with severe cracking, breakage or excessive flat wear cannot be repaired. Discarded tungsten carbide buttons are also recyclable for raw material remanufacturing, which greatly reduces customer procurement costs.

A: Yes. Jinzhou Carbide supports full customization of non-standard carbide buttons, including custom sizes, special shapes, exclusive cobalt ratios and customized alloy grades. We can produce fully compliant products strictly according to your drawings, samples and actual working condition requirements.
