Product Overview

C22000 brass is a high-copper brass alloy containing approximately 90% copper with a small addition of zinc to improve strength and workability. It is manufactured to ASTM B36, ASTM B134, and related standards for applications requiring superior formability, attractive appearance, and reliable corrosion resistance.

Produced through rolling, drawing, and annealing processes, C22000 brass offers excellent ductility, smooth surface quality, and stable dimensional performance. Its high copper content provides a distinctive reddish-gold appearance while maintaining good mechanical properties for fabrication and forming operations.

C22000 brass is extensively used in decorative panels, architectural trim, electrical hardware, roofing systems, and industrial formed components where appearance and durability are essential. It is widely applied across construction, electronics, HVAC, transportation, and general manufacturing industries.

Frequently Asked Questions About C22000 Commercial Bronze

Practical engineering answers on C22000 (90/10 commercial bronze): composition, properties, comparison to nearby brasses, standards and sourcing.

Despite the name, C22000 is a brass - commonly called commercial bronze or 90/10 brass - with 89.0-91.0% Cu and Zn balance (about 10%), Pb and Fe each at or below 0.05%. The high copper content gives it a warm bronze-gold color and better corrosion resistance than higher-zinc brasses, while staying cheaper than gilding metal (C21000).
Annealed C22000 has tensile strength about 200-270 MPa; half-hard (H02) rises to 300-370 MPa and hard (H04) to 380-450 MPa. Elongation runs 35-50% annealed down to about 5-15% at H04. Electrical conductivity is about 35-40% IACS.
Copper content is the differentiator: C21000 (94-96% Cu) is more formable and more copper-red; C22000 (89-91%) is slightly stronger and lower cost; C23000 (84-86% Cu, red brass) is one step lower in copper with a redder tone and the best dezincification resistance of the three. All three are low-lead (at or below 0.05% Pb) and cold-work well.
C22000 is covered by ASTM B36 (sheet/strip/rolled bar), B134 (wire), B135 (tube) and B927 (rod/shapes). It is used for architectural trim, roofing, ammunition components, electrical connectors, terminals and decorative hardware. The EN equivalent is CuZn10 (CW503L); Chinese GB is H90.
Yes. Linsy Copper supplies C22000 sheet, strip, wire, tube and bar to ASTM B36/B134/B135 with MTR/MTC on every order and SGS on request. Custom tempers, sizes and low-MOQ trial lots are supported, with lead times typically 10-60 days and quotes returned within 24 hours under RoHS/REACH compliance.
