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 rods

      There are two main grades depends on the different Proportion of the tungsten carbide grits

1. Grade	Chemical compositions（%）			Physical performance	Applications
   	WC	Cu+Zn+Sn	Co
   BT-Cu-30	64-67	30±2	3.8-4.2	Hardness: >160 HB  TRS: >690MPa	Down hole tools Plungers Shafts Agricultural/mining equipment Vlaves Turbine Blades Tool joints Extruder barrels and screws
   BT-Cu-40	53-56	40±2	4.6-4.8
   BT-Cu-45	48-52	45±2	4.2-4.5
   BT-Cu-50	44-48	50±2	3.8-4.2

   7	11.0-12.7	1/2-7/16

      Sizes, unit weight, grits sizes can be OEM.

1. 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 weldability 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.
