The grade for tungsten carbide strips

ISO Grade	Grain um	Density g/cm3	Hardness HRA	T.R.S N/mm3	Application
K20	Medium	14.6-15.0	90-90.5	2200-2400	High hardness,suitable for rough machining of iron,solid wood,dry wood or nonferrous metal,ceramic and other alloys.
K30	Fine	14.6-15.0	90-90.5	2600-2800	Hight toughness, easy to be brazed without heat preservation.Suitable for rosewood, solid wood, pinewood, and other wood with a lot of stammers.
K10	Ultrafine	14.6-15.0	92.5-93	1800-2000	High hardness, suitable for finish machining of iron, nonferrous metal, ceramic and other alloy,semi-finish machining of hardwood, chipboard, MDF and HDF. It's best to use silver soldering.
K40	Coarse	13.8-14.2	87.5-88	2800-3000	High toughness, difficult to break tooth. It's used specially for finger jointing tools.
K40	Medium	14-14.2	85-86	1700-1900	Mainly used for stamping molds and ceramic molds of electronic parts, corrosion-resistant instruments of petroleum machinery, non-magnetic.
K10	Fine	14.5	91	3000-3200	On the basis of ensuring high bending strength, the wear resistance of cemented carbide is enhanced, the cutting edge is dense and sharp, which is conducive to the flatness of processing and has good welding performance. It is used for food packaging, printing, aluminum foil, metalized film, gardens, textile, leather, plastic, rubber and other mechanical blades.
YN15	medium	13.7-14	85-86	1700-1900	Without cobalt, nickel binder, without magnetic, mainly used for stamping moulds and ceramic die of electronic components.

Production technics

Tungsten carbide 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. Tungsten 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. Carbide rectangular 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
