C21000 Gilding Brass sheet/plate
C21000 is a high-strength brass alloy primarily composed of copper (Cu: 94-97%), zinc (Zn: balance), and trace elements (e.g., Fe ≤0.10%, Pb ≤0.05%, impurities ≤0.2%) . Renowned for its excellent mechanical properties, high corrosion resistance, and superior thermal/electrical conductivity, it is widely used in marine engineering, chemical processing, and electrical applications

Parameter
Chemical Composition
Mechanical Properties
Dimensional Specifications

C21000 copper plates are available in diverse forms (sheets, coils, panels) with the following standard dimensions:

ParameterRange
Thickness0.5 mm – 120 mm (common industrial range: 1.0 mm – 10 mm)
Width2 mm – 2500 mm (customizable)
LengthStandard: 1 m, 2 m, 3 m, 6 m; customizable per requirements
Surface FinishMill, polished, brushed, mirror, sandblasted, etc.

Notes:

  • Thin sheets/coils (0.01–2.0 mm thickness) are also produced for precision applications .

  • Tolerances are tightly controlled (e.g., ±0.02 mm for thin strips) .


International Standards

C21000 copper plates conform to the following global standards:

Standard SystemDesignationScope
ASTM (USA)ASTM B36/B36M-23Covers brass plates, sheets, strips, and rolled bars (C21000 as "Gilding Metal").
GB (China)GB/T 5231-2012 (H95, H96)Equivalent to C21000; specifies mechanical properties and chemical composition.
JIS (Japan)JIS C2100Matches C21000 for industrial brass plates.
DIN (Germany)CuZn5 / 2.0220Denotes brass with ~95% Cu and 5% Zn, equivalent to C21000.
EN (Europe)CW500LStandardizes CuZn5 alloy for sheet/plate applications.



Key Cross-References:


  • ASTM C21000 ↔ GB H95/H96 ↔ JIS C2100 ↔ DIN CuZn5 .
  • ASTM B152-2009 and JIS H3250-2006 also apply to general brass plate specifications


Chemical Composition

C21000 is a high-copper brass alloy (also classified as "red brass") with a primary composition of copper (Cu) and zinc (Zn), along with trace elements. The exact chemical limits are standardized under ASTM specifications such as ASTM B36/B36M and ASTM B587. Here is the detailed composition:

ElementContent Range (wt%)Notes
Copper (Cu)94.0–96.0%Primary constituent
Zinc (Zn)BalanceTypically 4–6% (residual)
Lead (Pb)≤0.05%Strictly controlled impurity
Iron (Fe)≤0.05%Impurity limit per ASTM B36
Other Impurities≤0.3% (total)Includes P, Sb, Bi, etc. [1](#user-content-ref-4), [3](#user-content-ref-6), [18](#user-content-ref-12), [31](#user-content-ref-22)

Key Points:

  • C21000 is distinct from nickel-containing alloys (e.g., [31] incorrectly mention nickel; this appears to be an error, as other ASTM sources confirm it is a Cu-Zn alloy).

  • The alloy is often referenced as H95 in Chinese standards (GB/T 5231) and CuZn5 in European standards [35](#user-content-ref-22).



Mechanical Properties

C21000 exhibits a combination of high strength, ductility, and excellent cold-working capabilities. Properties vary depending on temper (annealed, cold-rolled, etc.):
