Product Overview

C27200 brass is a high-ductility copper-zinc alloy containing approximately 63% copper with balanced mechanical and processing properties for industrial applications. It is manufactured to ASTM B36, ASTM B134, and related standards for applications requiring reliable fabrication performance and attractive surface appearance.

Produced through precision rolling, drawing, and annealing processes, C27200 brass offers excellent cold working capability, good corrosion resistance, and stable dimensional performance. Its combination of strength, ductility, and surface quality makes it suitable for both structural and decorative applications.

C27200 brass is extensively used in decorative hardware, electrical fittings, radiator systems, industrial stamping parts, and architectural components where durability and appearance are important. It is widely applied across construction, HVAC, electronics, automotive, and general engineering industries.

Frequently Asked Questions

Common questions about C27200 yellow brass from engineers and sourcing teams.

C27200 (65/35, CuZn37) is a yellow brass with Cu 62.0-65.0%, Zn remainder, Pb <=0.07%, Fe <=0.07%, specified by ASTM B36 (and ASTM B135 for seamless tube). It is the most widely used brass for cold heading and deep drawing where material cost matters more than maximum ductility.
Annealed tensile strength is roughly 325-410 MPa with elongation up to 65%; half-hard tempers reach about 385-455 MPa. Conductivity is about 27.6% IACS and density about 8.44 g/cm3. Strength is controlled by temper, not heat treatment.
Choose C27200 when you want the lowest copper content (best material cost) and still need good cold formability for stamped or cold-headed parts. It sacrifices a little ductility and conductivity versus C26000/C26800 but is sufficient for fasteners, heat-exchanger shells, and pump liners.
C27200 solders and brazes readily; machinability is modest (about 30), so plan tooling and lubricant accordingly. It is not suited to hot working. Lead content is low (<0.07%), so it is generally RoHS-compatible outside specific lead exemptions.
Linsy Copper supplies C27200 to ASTM B36/B135 on request with mill test reports (MTR/MTC) per order and SGS available on request. Low-MOQ custom sizes and tempers are supported; quotes come back within about 1 hour and typical lead times are 10-60 days, with RoHS/REACH compliance.
