Tungsten carbide grades are like \u201crecipes\u201d \u2014 they mix tungsten carbide grains with a metal binder (usually cobalt) in different ways.
Some grades are harder, some are tougher, and each is made for a different kind of job.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\"Hard<\/figure>

It\u2019s about the mix of hard and tough<\/h3>

Carbide is made from tungsten carbide grains (WC) and a metal binder like cobalt.\nMore WC means higher hardness.\nMore binder means better toughness.\nEach grade has a different mix for different jobs.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\"Grain<\/figure>

Grain size changes how it behaves<\/h3>

Smaller grains make the material harder and better for fine cutting.\nLarger grains make it tougher and better for impact work.\nGrain size affects sharpness and durability.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Grades like YG6 or K20 follow a naming system.\nYG6 = 6% cobalt.\nK20 = for cutting wood or plastic.\nThe code helps match the right grade to the right job.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Hard grades resist wear but can crack under shock. Tough grades survive impact but wear faster. Most jobs need a balance.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
