Wire Brush Fill Material and Other Specifications

Brush One Fill Materials

Carbon Steel Fill: This material provides good wear characteristics and typically is used for aggressive surface preparation.

Stainless Steel (302): This premium grade of Stainless Steel is highly resistant to corrosion and high temperatures. It is recommended for stainless steel, aluminum and non-ferrous metals. It works well with chemicals and solvents and has a high resistance to wear. It has excellent spring characteristics and high levels of abrasion.

Brass: This is a soft flexible, non-corrosion filament that provides a high degree of abrasion without damaging the work surface. Great to use on metal equipment that is heavily soiled but cannot sustain heavy scratches or aggressive brushing.

Nylon: Superior long-lasting nylon can be used for both wet and dry applications. It is resistant to most acids and alkalines. Due to low water absorptions, it is also a great fill material for cleaning applications.

Horse Hair: This fill material works well for flux removal, flow through gluing applications and general clean up. It is also non-conductive.

Tynex: Tynex 612 Nylon filaments are not affected by chlorinated, petroleum hydrocarbons, ester solvents, or detergents. It is also resistant to attacks by rodents and fungi. This feature allows for safe storage and shelf life.

Silicon Impregnated Nylon: This material works well on ferrous materials due to its ability, as it breaks down, to continue to expose new aggregate on its brushing edge.

Density of Fill Material

The density of a brush is referring to the number of filament ends per given area of the brush face. The illustration below shows a wheel brush with low density on the left and one with high density on the right.

Allows the user greater flexibility for surface preparation. Good for varied and irregular surfaces. High density brushes tend to have better wear characteristics and typically give a better surface finish to the workpiece.

Brush Wire Diameters

Wire Diameter of Fill Material

Brush One provides many different diameters of fill materials. Shown below is the front view of piloted bonding brushes and the different wire diameters that we provide in stainless steel. The varied diameters allow for the unique fit to your brushing application. Larger sized wire diameters are typically used for more aggressive surface preparations.

Wire Form

Crimped Wire

The illustration below shows a single pane crimped filament. Dual pane filaments are most commonly used but we will use this type to outline our terminology.

Straight Wire

Used in Knotted Wire End Brushes, Knotted Wire Wheel Brushes and Knotted Wire Cup Brushes. The Twisted Knot style provides for aggressive surface preparations.

The illustration to the right shows a single wire and also a single twisted knot. A Standard Twist is shown, but straight wire is also used with Cable Twist and the Stringer Bead Twist. The Standard Twist is slightly flaired at the end which allows it to be a little more flexible on irregular applications.

The illustration to the right shows the face of a Twisted-In-Wire Wheel Brush. This style brush works aggressively on many standard and irregular surfaces.




Part Length (Trim Length)

The Piloted Bonding Brush trim length is the portion of the wire fill material that extends beyond the cup. A portion of that trim length is supported and held rigid by the bridle that is shown below.

Precision Pilots

Brush One pilots are precision ground to the tightest tolerances to ensure proper fit and performance. We can provide many different sizes and lengths to meet your needs.

New Bridle Material

In 2006, Brush One began the search to find a new bridle material with better wear characteristics than the material we had been using for over 20 years. We finally found that new material this year and are pleased to now offer it on our Piloted Bonding Brush line. See sample to the right.
