C23000 (ASTM B36) Red Brass Alloy Data Specifications

Highly resistant to stress corrosion cracking C230 or Red Brass as it is commonly known is a choice for a wide range of applications. Easily buffed or polished this material displays its own natural color well in applications like jewelry, plaques and other decorative or architectural items. Aside from looks this material also has moderate strength and is readily deep drawn or otherwise formed making it great for many industrial applications.
