Brass Machined Washers represent the pinnacle of precision fastener engineering, combining the excellent machinability of Brass alloys with advanced CNC manufacturing processes. These washers are manufactured from an extensive range of high-grade Brass materials including CZ121 (CW617N) lead-free brass, C360 free-machining brass, CuZn37 (CW508L), CuZn39Pb3 (CW614N), C26000 cartridge brass, C464 naval brass, and C27400 yellow brass using sophisticated multi-axis CNC turning centers and precision grinding operations.

Our comprehensive brass grade selection ensures optimal material choice for every application. CZ121 lead-free brass offers exceptional performance in potable water and food processing applications while maintaining excellent machinability characteristics. C360 free-machining brass provides the industry standard for high-speed production with superior surface finish capabilities. The manufacturing process involves bar feeding through Swiss-type automatic lathes, followed by chamfering operations on specialized chamfering machines to achieve smooth edges and precise dimensional control.

Our Brass Machined Washers are extensively used in electrical and electronic assemblies, plumbing fixtures, marine hardware, decorative applications, automotive components, and precision instrumentation where both functional performance and aesthetic appeal are critical. The natural antimicrobial properties of Brass make these washers particularly suitable for healthcare equipment and food processing machinery applications. Naval brass C464 grades provide enhanced corrosion resistance for marine environments, while cartridge brass C26000 offers superior formability for specialized applications.

Copper Machined Washers are precision-engineered components manufactured from high-purity Copper alloys including C11000 (Electrolytic Tough Pitch Copper), C10100 (Oxygen-Free Electronic Copper), and DHP Copper (C12200). These washers are produced using advanced CNC machining techniques including precision turning, facing, and drilling operations performed on Swiss-type automatic machines equipped with live tooling capabilities.

The manufacturing process begins with certified Copper bar stock that undergoes rigorous incoming quality inspection including chemical composition analysis and mechanical property verification. The machining operations are performed under controlled coolant conditions to prevent work hardening and maintain optimal surface finish. Post-machining operations include deburring, cleaning, and optional surface treatments such as tin plating or nickel plating for enhanced performance characteristics.

ISO 7089 Machined Washers are manufactured in strict accordance with the International Organization for Standardization specifications for plain washers with normal series dimensions. These washers feature precise outside diameter to inside diameter ratios of 2.2:1 and thickness tolerances maintained within ±0.1mm. Our ISO 7089 compliant washers are available in both Brass and Copper materials, manufactured using precision CNC turning operations followed by automated deburring processes.

The ISO 7089 standard specifies dimensional requirements for washers used with bolts, screws, and nuts in general engineering applications. Our manufacturing process ensures compliance with the geometric tolerances specified in ISO 7089, including concentricity requirements of ±0.05mm and surface roughness values not exceeding Ra 3.2μm on critical surfaces.

DIN 125 and DIN 126 Machined Washers represent German engineering excellence in fastener standardization. DIN 125 specifies plain washers for normal series applications, while DIN 126 covers washers for large series applications with increased outside diameters for enhanced load distribution. These washers are manufactured using precision CNC machining processes with tolerances maintained according to DIN 7168 medium class requirements.

Our DIN 125 and DIN 126 compliant washers undergo comprehensive quality control procedures including dimensional verification using coordinate measuring machines (CMM), surface roughness testing, and material composition analysis. The manufacturing process incorporates German-engineered quality systems ensuring consistent production output and dimensional accuracy across all produced batches.

Brass Chamfered Washers feature precision-machined chamfers on both inner and outer edges, facilitating easier assembly and reducing stress concentrations during fastening operations. The chamfering operation is performed using specialized chamfering tools on CNC turning centers, creating consistent 45-degree chamfers with controlled depth and surface finish. These washers are particularly beneficial in applications requiring frequent assembly and disassembly operations.

The chamfering process not only improves functional performance but also enhances the aesthetic appearance of the finished components. Our Brass Chamfered Washers are manufactured from lead-free Brass alloys where required for environmental compliance, ensuring suitability for potable water applications and RoHS-compliant electronic assemblies.

Copper Turned Washers and Brass Turned Washers are manufactured using advanced CNC turning processes that provide superior dimensional accuracy and surface finish compared to stamped alternatives. The turning operation allows for precise control of wall thickness variations, concentricity, and surface texture, resulting in components that perform consistently under demanding operating conditions.

Our turning operations utilize Swiss-type automatic lathes equipped with high-speed spindles and precision tool holding systems. The process parameters are optimized for each material grade to minimize tool wear while maximizing surface quality and dimensional stability. Post-turning operations include automated deburring and optional secondary machining for specialized features such as counterbores or grooves.

Our comprehensive range of Brass and Copper Machined Washers are available in standard metric and imperial dimensions to meet global customer requirements. The following dimension charts cover ISO 7089, DIN 125, DIN 126, and ANSI standards commonly specified in international engineering applications.
