Joint Carbide was founded in 2007 in Zigong, China, as a professional manufacturer and high-tech enterprise. We specialize in the research, development, production, and sales of carbide burrs, carbide grit, carbide rods, carbide powder, wear parts, and carbide scrap recycling. Over 19 years, the group has grown to six entities with three factories and 418 sets of 5-axis CNC machines.

The group currently comprises six entities across China:

We serve 20+ major B2B industries worldwide, including:

We offer both standard and special cut types to match every machining application:

Follow our 10-step selection guide to find the perfect burr:

• Choose the appropriate rotational speed before grinding.
• Select a suitable burr shape, diameter and cut type for the material.
• Confirm the shank and chuck are firmly connected before use.
• Avoid excessive pressure -- high heat shortens burr lifespan.
• Slow down the machine if the burr gets stuck in the material.
• Never use burrs in a combustible gas environment.
• Always wear safety glasses and gloves before grinding.

With 418 sets of 5-axis CNC machines across three factories, our daily production capacity reaches 25,000-30,000 pieces of carbide burrs. We are China's first carbide burr manufacturer with a complete material supply chain, covering every step in-house:

Tungsten carbide grit is produced by crushing and grading YG/YT tungsten carbide into sized particles. It serves as a key raw material for carbide composite welding rods, spray welding, and surfacing materials.

It is widely applied for surface cladding, pre-strengthening, and wear repair across:

High-entropy alloy grit is made from a Ti-Cr-Mn-W-Mo alloy system. Its wear performance can replace over 90% of tungsten carbide while offering distinct advantages:

Primary applications: surface welding, brazing, spray welding and wear-resistant substrate casting in aerospace, defense, energy, chemical, automotive, and general industrial sectors.

We produce two main types of carbide rods:

Carbide rods are widely used for wear resistance, hardfacing, and component repair in:

Major overseas customer groups include:

• Welding consumables importers and hardfacing material suppliers
• Mining, petroleum, metallurgical, agricultural and construction machinery manufacturers
• Laser cladding and welding processing manufacturers

Thermal spray powders are widely applied for wear, corrosion, high-temperature oxidation, thermal barrier, and friction-resistant coatings in:

Major customers include aircraft OEMs, engine makers, MRO providers, oilfield service firms, power equipment manufacturers, and thermal spray coating service vendors.
