How to Ask for Tungsten Carbide Quotation: Information You Need to Prepare

Introduction

Many tungsten carbide buyers send inquiries with only simple photos or rough dimensions, which often leads to slow replies, unclear pricing or big price gaps between different suppliers. To get a fast, accurate quotation from a carbide manufacturer, you need to organize complete technical information in your inquiry email.

Full information helps the engineering team evaluate manufacturing difficulty, tooling cost, machining time and inspection workload. This guide covers all items you need to prepare before requesting a tungsten carbide quote, whether you need carbide rods, blades, dies, wear plates or custom-shaped carbide parts.

Part Drawings or Samples

2D CAD drawings with dimension marks are the most preferred document for custom carbide parts. Drawings should include views of all features, holes, chamfers, radii and edge details. PDF, DWG, DXF formats are widely accepted.

If you do not have formal drawings, physical samples with clear photos and hand-measured dimensions can work for preliminary quotation. But final production still requires formal drawings. Photos alone are not enough for precise pricing because hidden internal features cannot be judged.

Carbide Grade & Material Requirements

Specify the tungsten carbide grade if you already have a defined grade, such as YG6, YG8 or equivalent international grades. If you are unsure which grade to use, describe your working conditions so the supplier can recommend a suitable grade.

Key material indicators you can mention: cobalt content, hardness (HRA), transverse rupture strength (TRS), density. For special environments, state anti-corrosion or anti-cobalt leaching requirements.

Dimensions, Tolerance & Surface Finish

Tighter tolerance and higher surface finish will increase machining cost. Clearly mark which dimensions are critical and which can use standard tolerance to avoid unnecessary cost.

Order Quantity & Sampling Plan

Tell the supplier your sample quantity and mass production quantity. Carbide manufacturing involves tooling setup cost. Unit price will drop obviously when production volume increases.

Also clarify: Do you need prototype samples first? What is the estimated annual consumption? This helps the factory arrange production schedule and offer better bulk pricing.

Working Application & Operating Conditions

Even if you do not know the carbide grade, describing your application helps the manufacturer select proper material and processing method. Please include:

• Part function: cold forging die, wire drawing die, cutting blade, wear liner, etc.
• Load type: continuous wear, impact load, cyclic fatigue load
• Workpiece material: steel, copper, aluminum, wire material
• Cooling medium: dry working, water-based coolant, acidic liquid
• Working temperature range

Other Special Requirements

• Inspection documents: dimension report, hardness test, density report, TRS certificate
• Packaging requirements: anti-collision packaging for precision carbide parts
• Lead time target for samples and mass goods
• Shipping term and destination port
• Surface coating: TiN, TiCN, AlTiN if coating service is needed

Common Mistakes That Affect Quotation

• Only sending photos without dimensions, leading to estimated rough price only
• Missing tolerance requirements. The factory quotes based on standard tolerance, price changes when tight tolerance is added later
• Not mentioning impact load, supplier selects low toughness carbide grade incorrectly
• Changing drawing after sample quotation, which causes price revision
