Wire size ranges from .003" to .020". Abrasive Nylon ranges from 500 Grit (fine) to 46 Grit (coarse). Other synthetic materials are generally available in .005" through .020" for end brush applications. End brush diameters include 3/8", ½". ¾", and 1" brush part. Standard shank dimensions are ¼" wide by 7/8" long. Standard trim length for Solid Fill End brushes is 1". Adding bridles to an end-brush reduces the tendency to flare-out during operation and concentrates the wire points on the work surface directly in front of the brush. Bridles may be removed as the brush wears.

Side Bottom Brushes

Steel Wires:
Wire brushes made from steel wire are suitable for a wide variety of applications and are generally the most economical and most widely available of the different wire brush options. Steel wire is the hardest of the commonly offered brush wires, providing a high fatigue life and durable cutting action. Steel wire is most appropriate for work on steel and iron work pieces, but may also be used on wood, aluminum, brass and copper; however the softer the material to be brushed, the more likely that a steel wire brush will cut into the material and remove base material in addition to the targeted coating or contamination. Steel wire is appropriate for constant operating temperatures up to 275° F, but can be used where the brush will come in contact with higher temperatures for shorter periods of time. When ambient temperatures will exceed 275°F, stainless steel wire should be considered.

Stainless steel Wires:
Wire brushes made from stainless steel wire are suitable for work on stainless steel and aluminum fabricated products, and for use in direct food-contact applications, in higher heat situations, and in environments where the brush wire may be exposed to moisture or high humidity on a repeated basis. We feature 304 Stainless Steel wire to offer a higher analysis wire to customers working on either 302 0r 304 stainless work pieces. Stainless steel wire is generally recommended for continuous operating temperatures up to 600°F.

Brass Wires:
Brass wire is softer than steel wire or stainless steel wire, and offers a brushing action that will not scratch harder metals. Our brass wire is Alloy 260, composed of 70% Copper and 30% Zinc. If your work-piece is either brass or copper, then brass wire is the most suitable choice. Brass wire (as well as bronze wire) will not generate sparks when struck against other metallic surfaces, and is suitable for hazardous environments (1) . Brass wire is also an excellent conductor of electrical energy (28% IACS), and is suitable for static reduction applications . Brass is appropriate for operating environments up to 300°F constant temperature. Brass wire is also relatively corrosion resistant.

Popular Applications for Brass Wire brushes:

• Cleaning plastic extrusion parts, including molds, dies, and extruder barrels
• Cleaning machine parts where sparks might pose a risk of fire or explosion
• Cleaning metal parts without removing any of the base material.
• Satin finishing aluminum extrusions or sheet
• Static reduction brushes for industrial environments

Bronze Wire:
Bronze wire is harder and stiffer than brass wire. We utilize a Phosphor Bronze wire, Alloy 510, consisting of 95% Copper and 5% Tin. The presence of Tin improves fatigue strength and tensile strength over the C-260 brass wire.

Bronze wire will not generate sparks when struck against other metallic surfaces, and is suitable for hazardous environments (1) . Bronze wire is a good conductor of electrical energy (15% IACS), and is suitable for static reduction applications . Bronze is appropriate for operating environments up to 400°F constant temperature. Bronze wire is also relatively corrosion resistant.

Popular Applications for Bronze Wire brushes: :

• Cleaning plastic extrusion parts, including molds, dies, and extruder barrels
• Wiping tenter frame rollers in synthetic fiber plants
• Cleaning machine parts where sparks might pose a risk of fire or explosion
• Cleaning metal parts without removing any of the base material.
• Satin finishing aluminum extrusions or sheet
• Static reduction brushes for industrial environment.

Nylon Bristles:
Nylon filled industrial brushes are suitable for a range of applications from aggressive scrubbing to dusting, in both dry and wet environments. Brushes with Nylon fill offer the following characteristics in most applications: excellent fatigue life, good abrasion resistance, low to moderate absorption of water (3% to 9%) leading to only a temporary reduction in stiffness, an excellent bend recovery rate, resistance to most common solvents, and suitability for use in weak acids. Nylon 6.6 is a medium grade suitable for most dry industrial applications and constitutes our regular duty filament for industrial applications. Nylon 6.6 has a higher moisture absorption rate at 9%, and therefore loses approximately half its stiffness when exposed to wet environments. Nylon 6.6 also has limited resistance to many common chemicals. Nylon 6.12 is a higher performance grade for industrial and food-contact applications with the following attributes: a significantly greater wet stiffness modulus than 6.6 nylon, resistance to petroleum distillates, benzene aromatic hydrocarbons, ethyl acetate esters, and trichloroethylene hydrocarbons. Nylon 6.12 is FDA approved for direct food contact.

Abrasive Bristles:
Abrasive grit encapsulated into the extruded nylon filament allows an abrasive nylon brush to perform deburring, edge blending, and surface finishing. Power brushes and Cylinder brushes made with abrasive nylon deliver features of a brush: flexibility of design and conformability to irregular surfaces, while also imparting the benefits of an abrasive: selection of grit sizes to control finish, and functionality for deburring, cleaning, surface finishing, and edge blending. Abrasive Nylon is suitable for use on a broad range of materials.

End brushes:
Using the sides of the filaments as flexible files, end brushes filled with abrasive nylon can clean internal surfaces and deburr internal threads. A bridled end brush can be used to deburr or clean a confined or hard to reach area.

For many dry industrial applications Nylon 6-6 is acceptable, while more demanding applications may require the additional heat resistance, lower water absorption and increased toughness of a Nylon 6.12. Both Silicon Carbide grit and Aluminum Oxide grit are available, and approximate a 30% loading by weight in the extruded nylon filament. Silicon Carbide is more commonly used because it is harder and sharper than aluminum oxide, and it is preferred for finishing ferrous metals. Aluminum oxide grit is less likely to fracture and is preferred for finishing softer metals including stainless steel and aluminum, wood and plastics. Aluminum Oxide also eliminates the small risk of contamination of the stainless steel or aluminum surface by free carbon deposits from the silicon carbide.

Different from a typical wire brush, where the operating guidance is to use the tips of the wires to do the work with light pressure and high brush face speed, abrasive nylon brushes abrade with the sides of the filament as well as the tips because the grit is spread randomly throughout the filament. As a result, lower brush speeds and greater engagement of the work-piece into the brush face may contribute to increased brush effectiveness. A work-piece requiring finishing of contoured or recessed surfaces can be accommodated with a longer trim brush, controlling the brush speed, and by engaging the work-piece into the brush face up to 1/8th of the length of the brush trim.
