Product Description Description:1. Tungsten carbide composite rod is made of cemented carbide tips and Ni/Ag(Cu)alloy. The carbide tips always be tungsten carbide crushed grits, carbide wear inserts, like the carbide star shape inserts, carbide pyramid shape inserts, shark shape inserts and so on. Sometimes, the carbide tips can be tungsten carbide powder. The economy choice is tungsten carbide crushed grits. If you want to higher durable than carbide grits, carbide inserts is better. However the cemented carbide/crushed carbide with sharp edge has excellent wear resistance and cutting ability too.2. The hardness is 89-91 HRA, the binder metal is Ni and copper alloy, strength can up to 690MPa, hardness HB≥160.3. To brief, most of the Composite rod made using crushed sintered Tungsten Carbide grains bonded with a bronze nickel matrix,(Cu 50 Zn 40 Ni 10) with a low melting point ( 870°C ). The grain sizes of the carbide grits:1. 1/8-1/16 in. ( 3.2-1.6 mm )2. 3/16-1/8 in. (4.8-3.2 mm)3. 1/4-3/16 in. (6.3-4.8 mm)4. 3/8-5/16 in. (9.5-7.9 mm)5. 5/16-1/4 in. (7.9 -6.3 mm)6. 3/8-1/4 in. (9.5-6.3 mm)7. 1/2-5/16 in. (12.7-7.9 mm)The grades of the composite rodsThere are main grades depends on the different Proportion of the tungsten carbide gritsGradeChemical compositions(%) Physical performanceApplications WCCu+Zn+SnCo BT-Cu-3064-6730±23.8-4.2 Hardness: >160 HB TRS: >690MPaDown hole toolsPlungersShaftsAgricultural/mining equipmentVlavesTurbine BladesTool jointsExtruder barrels and screwsBT-Cu-4053-5640±24.6-4.8 BT-Cu-4548-5245±24.2-4.5 BT-Cu-5044-4850±23.8-4.2 ItemCarbide grits size Apperance Available width (mm) Available length (mm) (mm)(inch) 11.6-3.21/8-1/16 Bare or with fluxed-coating (20-22 ) (18-20 ) (10-12) 280- 45023.2-4.83/16-1/8 34.8-6.41/4-3/16 46.4-8.05/16-1/4 58.0-9.53/8-5/16 69.5-11.07/16-3/8 711.0-12.71/2-7/16 Sizes, unit weight, grits sizes can be OEM.Composite rod welding has been acknowledged throughout oil drilling, mining and construction industry worldwide for its extra hardness and high wear resistant properties. The use is even spreading to more industries and gets greater uses. Composite rod welding has wear and cutting properties coupled by high-end weld ability and low fuming, allowing the material to use in stabilizers, reamers, drill pipe joints, construction drilling, hydraulic-cutter, pipe cutter blades, core bit, scraper, twist drill, milling and grinding shoes etc.FAQ of Tungsten carbide composite rodQ: Are you trading company or manufacturer ?A: We are factory.Q: How long is your delivery time?A: Generally within 7 days if the goods are in stock. or it is 15-20 days if the goods are not in stock,it is according to quantity.Q: Do you provide samples ? is it free or extra ?A: Yes, we could offer the sample for free charge but do not pay the cost of freight.Q: What is your terms of payment ?A: Payment<=1000 USD, 100% in advance.
