Our tungsten carbide composition welding rods are very high in quality and best in price.
Description:
1. The tungsten carbide composite rod is made of cemented carbide tips and Ni/Ag(Cu)alloy. The carbide tips are always 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 economic choice is tungsten carbide crushed grits. If you want higher durability than carbide grits, carbide inserts are better. However, the cemented carbide/crushed carbide with a 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 ).
There are different types of tungsten carbide composition welding rods in our factory:
1. Copper welding material + tungsten carbide grits.
2. Nickle welding material + tungsten carbide grits.
With each different material, there are two different percentages of tungsten carbide grits too:
1. 70% tungsten carbide grits.
2. 30% tungsten carbide grits. Blanch welding material.
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)
Carbidide welding rods come in different lengths and widths.
The grades of the composite rods
There are main grades that depend on the different proportions of the tungsten carbide grits

Sizes, unit weight, and grit sizes can be OEM.Composite rod welding has been acknowledged throughout the 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 is getting greater use. Composite rod welding has wear and cutting properties coupled by high-end weld ability and low fuming, allowing the material to be used in stabilizers, reamers, drill pipe joints, construction drilling, hydraulic-cutter, pipe cutter blades, core bit, scraper, twist drill, milling and grinding shoes, etc.
Our packing of tungsten carbide composition welding rods
1. First in PP bags
2. Then, PP bags are put into paper boxes.
3. 2 Paper boxes into paper cartons.
4. Paper cartons onto a wooden case.
