FAQ

Q: What are the mechanical properties of C21000?
A: Typical mechanical properties of C21000 (annealed condition) include a tensile strength of about 38–45 ksi (260–310 MPa), yield strength around 10–15 ksi (70–105 MPa), and elongation of 45–55%. Hardness is approximately 45–55 HRB.
Q: What is the equivalent of C21000 in European standards?
A: C21000 is roughly equivalent to CuZn5 in EN standards (EN 1652) and may correspond to C2100 in JIS (Japanese standards). However, exact equivalents depend on specific composition and application requirements.
Q: What is C21000 brass used for?
A: C21000 is commonly used in architectural decoration, jewelry crafting, medals, nameplates, electrical connectors, and decorative hardware due to its aesthetic appeal, formability, and good conductivity.
Q: Can C21000 be welded or brazed?
A: Yes, C21000 can be welded and brazed using appropriate techniques. Oxyacetylene welding, TIG, and resistance welding are suitable, while brazing with silver-based or phosphorus-copper fillers is common.
Q: Is C21000 corrosion resistant?
A: C21000 offers good corrosion resistance in atmospheric, freshwater, and mild chemical environments. However, it is not recommended for prolonged exposure to seawater or highly acidic/alkaline conditions.
Q: What is the difference between C21000 and C26000?
A: The primary difference is copper content: C21000 (~95% Cu) is softer and more ductile with a reddish-gold color, while C26000 (~70% Cu) is stronger and more widely used in cartridges and mechanical parts.
Q: Where can I buy C21000 brass sheet or strip?
A: C21000 products are supplied by specialized metal distributors, mills, and online metal suppliers. Ensure the supplier provides certified Mill Test Reports (MTR) for quality assurance.
Q: Does C21000 contain lead?
A: Standard C21000 is typically lead-free. However, always verify with the supplier's material certification to ensure compliance with regulations like RoHS or NSF for specific applications.
Q: What tempers or forms is C21000 available in?
A: C21000 is commonly supplied in annealed (soft), half-hard, and hard tempers. Available forms include sheet, strip, foil, wire, tube, and occasionally rod.
