Material
Brass Coated Wire
Brass Coated Wire is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. To define stiffness, confirm the material together with filament diameter, free trim length, density, grade, and service conditions.

Material Overview
Brass-coated wire is generally a ferrous wire with a thin copper-alloy surface layer used to alter handling, corrosion or contact characteristics.
In a finished brush, Brass Coated Wire does not create a fixed stiffness by itself. Brush force and recovery come from the complete filament geometry and contact setting, not just the polymer name. Service conditions must also be considered.
Material Properties
| Steel core diameter | 0.10–0.60 mm |
|---|---|
| Brass coating | about 0.2–1.0 µm |
| Density | about 7.8–8.0 g/cm³ |
| Corrosion resistance | higher than bare carbon steel in dry service |

Frequently Asked Questions
What are the key properties of Brass Coated Wire brush material?
Brass-coated wire is generally a ferrous wire with a thin copper-alloy surface layer used to alter handling, corrosion or contact characteristics. Direct data: Steel core diameter: 0.10–0.60 mm; Brass coating: about 0.2–1.0 µm; Density: about 7.8–8.0 g/cm³; Brush operating range: -20–250°C; Corrosion resistance: higher than bare carbon steel in dry service.
Where is Brass Coated Wire used in cleaning brushes?
General wire-wheel and bore cleaning where a steel core is wanted with a brass-colored surface and reduced initial harshness.
How does filament geometry change Brass Coated Wire brush stiffness?
Brass Coated Wire changes brush stiffness through filament diameter, free trim, density, crimp, and contact. Use finer filament and longer trim for conformable contact; use coarser filament, shorter trim, or higher density for stronger displacement or cutting.
When should Brass Coated Wire be replaced by another material?
Compare Brass Coated Wire with Steel wire, stainless wire, nylon. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
