Mount Joy Wire is a leading ISO 9001-certified brush wire manufacturer that produces precision products across multiple material grades and temper conditions, supporting a wide range of industrial applications. In-house heat-treatment capabilities and rigorous quality control deliver the consistency required for twisted-in-wire brushes, industrial brushes, and surface-preparation equipment.

We manufacture brush wire across multiple material grades and temper conditions to match specific brush manufacturing requirements. Our integrated production operations allow us to control mechanical properties and surface characteristics throughout production. Each product category is manufactured to maintain consistent quality and performance standards.
We carry the following high-quality brush wire products:
Brush wire is available in multiple packaging configurations to support different production processes and handling requirements. As a trusted brush wire manufacturer, Mount Joy Wire offers flexible packaging options that accommodate both high-volume manufacturing and more specialized low-volume production runs.
Choose from our line-up of brush wire types:
Mount Joy Wire produces brush wire in diameters ranging from ultra-fine to heavy, in carbon steel, stainless steel, and specialty materials. Our manufacturing capabilities maintain tight dimensional tolerances to ensure consistent performance in brush production. Custom sizing is available to meet application-specific requirements.
Available sizes include:
Rigorous physical testing and microscopic analysis by our metallurgical experts confirm that all brush wire products meet exact customer specifications. As a premier brush wire manufacturer, Mount Joy Wire performs in-house testing and evaluation at our ISO 9001-certified Pennsylvania facility to verify material properties at every production stage. Dimensional accuracy is continuously monitored via laser gauging to maintain tight tolerances.
Our verification systems deliver consistent quality across every wire category we manufacture. Continuous quality improvement protocols ensure products perform reliably in a wide range of aerospace, medical, automotive, and industrial applications. This comprehensive testing approach maintains the material integrity required for critical brush manufacturing operations.

We perform all oil tempering, patenting, and annealing operations at our Pennsylvania facility, giving us direct control over the fatigue resistance and ductility critical for high-performance brush filaments. This complete range of heat-treatment operations under one roof is a capability few wire manufacturers can offer. Our integrated manufacturing approach eliminates the material inconsistencies that cause breakage during crimping, twisting, or forming.
Both Annealed at Finish and Annealed in Process options are available alongside spheroidized annealing for high-carbon wire applications. Engineering wire to specific tensile strength requirements becomes possible through these in-house processes. These tailored heat-treatment cycles deliver wire that holds a uniform shape and performs reliably in your specific power, scratch, or twisted-in-wire brush manufacturing operations.
