Material
Brass Wire
Brass Wire is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. For a usable stiffness specification, provide the material, filament diameter, free trim, density, grade, and operating conditions.
Material Overview
Brass is a copper-zinc alloy whose strength, ductility and corrosion behavior vary with zinc content and temper.
In a finished brush, Brass Wire does not create a fixed stiffness by itself. Working stiffness and recovery depend on filament size, free trim, density, tuft pattern, and contact. Grade and operating conditions determine how stable that behavior remains.
Material Properties
| Density | 8.4–8.7 g/cm³ |
|---|---|
| Wire diameter | 0.08–0.50 mm |
| Hardness | about HV 80–180 |
| Electrical conductivity | about 15–30% IACS by alloy |

Frequently Asked Questions
What are the key properties of Brass Wire brush material?
Brass is a copper-zinc alloy whose strength, ductility and corrosion behavior vary with zinc content and temper. Direct data: Density: 8.4–8.7 g/cm³; Wire diameter: 0.08–0.50 mm; Hardness: about HV 80–180; Brush operating range: -20–200°C; Electrical conductivity: about 15–30% IACS by alloy.
Where is Brass Wire used in cleaning brushes?
Gentle oxide removal, mold cleaning and surface work on brass, copper and other softer nonferrous parts.
How does filament geometry change Brass Wire brush stiffness?
Brass 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 Wire be replaced by another material?
Compare Brass 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.
