Tungsten carbide strips are widely used in manufacturing woodworking blades, stamping dies, wear parts, etc. we offers top and consistent quality carbide strips engineered through several procedures, including micro-grain tungsten carbide powder mixture, ball milling, pressing and forming, sinter-HIP, and quality inspection. The sinter-HIP reduces the porosity of our tungsten carbide strips and increases the density, thus ensuring our quality consistency. Meanwhile, the isostatic pressing guarantees density uniformity. We supply varied grades, We also offer customization services according to your requirements.

Features:

• 100% virgin WC powder;
• Outstanding wear, corrosion, and high-temperature resistance;
• Excellent chemical stability (acid, alkali, oxidation resistance);

The grade for carbide rectangular strips

Carbide strips are referring the rectangular tungsten carbide rod, also known as tungsten carbide flats.It is produced by the same way as carbide rod, through powder(Mainly WC and Co powder as per formula) mixture, ball milling, spray tower drying, extruding, drying, sintering, (and cutting or grinding if necessary) final inspection, packing, then delivery, middle inspection is done after each process to make sure only the qualified products can be moved to next production process.

The carbon sulfur analyzer, HRA tester, TRS tester, Metallographic microscope(Check microstructure), coercive force tester, cobalt magnetic tester are used to inspect and make sure the material of carbide strip is good qualified, besides, drop test is added specially to the carbide strip inspection to make sure there is no material flaw in the whole long strip. And the size inspection as per order.

Application of carbide strip:

1. Woodworking blades.
2. Cut to small pieces to be welded as cutter blades.
3. Grinding support plate in grinding machines.
4. Other applications.

The size for carbide strips

Production technics

• Carbide wear strips are mainly made from wolfram carbide and cobalt powder by powder metallurgy methods. The main production process of tungsten carbide bar stock is powder milling, ball milling, pressing and sintering. For different uses, the content of WC and Co in tungsten carbide flat bar is not the same.

Application

• Tungsten carbide flat strips are mainly used in woodworking, metalworking, molds, petroleum machinery, textile tools and other industries. Solid carbide square bar is mainly used to process solid wood, density board, gray cast iron, non-ferrous metal materials, chilled cast iron, hardened steel, PCB, brake materials, etc. Sintered carbide strips of suitable material should be selected according to the specific application.

Main Process flow

Powder milling→ formula according to application requirements → wet milling → mixing → crushing → drying → sieving → adding forming agent → redrying → sieving to obtain cemented carbide powder→ granulating → pressing → forming → low-pressure sintering →blanks→Flaw inspection→Packing→Warehousing
