Behind every finished bushing is a complex manufacturing process that turns fine tungsten and metal powders into a precision-engineered part.<\/p>

Each step \u2014 from powder preparation to final polishing \u2014 determines how long the bushing will last in service.<\/p>

In this article, we\u2019ll explain the complete manufacturing process of tungsten carbide bushings in simple terms, highlight why each step matters, and show how strict process control ensures durability and precision.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Raw Material Selection<\/b><\/h2>

\"\"<\/p>

The process begins with choosing the right tungsten carbide (WC) powder<\/a> and binder metal. The most common binders are cobalt (Co) and nickel (Ni).<\/p>

The combination ratio affects \u0635\u0644\u0627\u0628\u0629<\/a>, \u0635\u0644\u0627\u0628\u0629<\/a>\u060c \u0648 \u0645\u0642\u0627\u0648\u0645\u0629 \u0627\u0644\u062a\u0622\u0643\u0644<\/a>. Fine-grain powders are used for bushings that need high strength and mirror surface finishes.<\/p>

The right balance between WC and binder defines how the bushing will perform \u2014 a higher binder content improves toughness, while a lower one increases hardness.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Powder Mixing and Homogenization<\/b><\/h2>

\"\"<\/p>

The selected powders are mixed in a ball mill with a small amount of ethanol or paraffin as a binder liquid. The goal is to achieve uniform particle distribution.<\/p>

This step ensures that the final carbide has consistent \u0643\u062b\u0627\u0641\u0629<\/a> and mechanical properties across the entire part.<\/p>
