Brass CZ121 Machined Parts Overview
Brass CZ121 Machined Parts represent the pinnacle of precision engineering in free cutting Brass applications. CZ121, also known as C36000 or 360 Brass in ASTM nomenclature, is a leaded Brass alloy containing approximately 61.5% Copper, 35.5% Zinc, and 3% Lead. This composition provides exceptional machinability, making it the preferred choice for high-volume production of intricate components. Our Brass CZ121 machined parts demonstrate superior dimensional accuracy, excellent surface finish, and consistent mechanical properties that meet stringent quality requirements across various industries. The lead content in CZ121 acts as a chip breaker, enabling faster machining speeds and longer tool life, which translates to cost-effective production and competitive pricing for our customers.
Brass CZ121 CNC Components manufactured in our facility utilize advanced computer numerical control technology to achieve complex geometries with exceptional precision. Our CNC machining capabilities include multi-axis turning, milling, drilling, tapping, and threading operations that produce components with tolerances ranging from ±0.01mm to ±0.005mm depending on the application requirements. The CNC process ensures repeatability and consistency across large production runs, making CZ121 CNC components ideal for automotive, electronics, plumbing, and instrumentation applications where precision and reliability are paramount.
Free Cutting Brass CNC Machined Parts leverage the superior machinability characteristics of CZ121 alloy to produce components with excellent surface finish and dimensional accuracy. The free cutting properties of this Brass alloy result from the lead content, which forms discrete particles that act as internal lubricants during machining operations. This characteristic enables high cutting speeds, reduced tool wear, and excellent chip formation, resulting in superior surface quality and faster production cycles.
Brass Free Machining Alloy CZ121 belongs to the family of free machining Brass alloys specifically designed for automatic screw machine operations and high-speed CNC machining. The alloy composition is optimized to provide the best balance between machinability, mechanical properties, and corrosion resistance. Our free machining Brass components exhibit excellent strength-to-weight ratio, natural antimicrobial properties, and attractive golden appearance that makes them suitable for both functional and decorative applications.
CZ121 Brass Alloy specifications conform to multiple international standards including BS EN 12164, ASTM B16, DIN 17672, and JIS H3250. The alloy designation CZ121 under European standards corresponds to UNS C36000 (USA), CuZn36Pb3 (Germany), and C3604 (Japan). This standardization ensures global compatibility and consistent quality across different markets and applications.
CZ 121 Brass Composition consists of Copper (60-63%), Zinc (35.5-37.5%), Lead (2.5-3.7%), and trace amounts of Iron, Aluminum, and other elements totaling less than 0.5%. This carefully controlled composition provides optimal machinability while maintaining adequate mechanical properties including tensile strength of 338-469 MPa, yield strength of 124-310 MPa, and elongation of 8-23% depending on the temper condition.
CZ121 Brass Turned Parts represent a significant portion of our production capacity, utilizing precision turning operations to create cylindrical components, shafts, bushings, and threaded fasteners. Our turning capabilities include both conventional and CNC turning with bar capacity up to 65mm diameter and length up to 300mm for single operations. Multi-spindle turning operations enable cost-effective production of high-volume components with consistent quality and dimensional accuracy.
