DuraNib™ Carbide Nibs

DuraNib carbide nib blanks are a revolutionary cobalt-free cemented carbide grade designed for drawing non-ferrous wire made of materials such as aluminum, copper, or titanium.

DuraNib carbide nib blanks are available in various standard geometries such as ISO, JIS, and DIN or are tailor-made to your design. However, despite no size limitation, Hyperion recommends using DuraNib in die blanks with bore sizes above 3 mm, generally using dry lubricants during the drawing process.

As a cemented carbide grade, wire drawing blanks and dies made of DuraNib can be finished with the same process parameters as conventional carbides. Toolmakers can use the same diamond compounds and machinery used for conventional carbide grades.

DuraNib carbide nibs can prevent wire die galling. For example, when drawing aluminum high-voltage conductors, the metal is easily affected by galling due to its cold-welding of soft metals placed under high friction pressures. Due to its very low wear properties, DuraNib carbide blanks can reduce surface cohesion and resist galling buildup between the wire and the die within high temperatures.

DuraNib carbide nibs provide several benefits for drawing wire. First, its cobalt-free properties offer a healthy and safe environment when utilizing the product. It also provides several benefits that allow it to draw aluminum, copper, or titanium compared to other carbide products such as:

• Lower friction coefficient

• Prevents material adhesion

• Maintains stable hardness at extremely high temperatures

• Great corrosion resistance to acidic metals

• High toughness and wear resistance

DuraNib carbide nibs are used for drawing non-ferrous wires such as aluminum or copper high-voltage conductors, titanium for medical applications, and conforming copper between other applications.
