Products Description
C28000 Muntz Metal, also known as 60/40 brass, is a copper-zinc alloy available in sheet and plate forms, celebrated for its exceptional hot-working properties. While it offers less corrosion resistance than C464 Naval Brass, C28000 is widely used in architectural applications, including decorative panels, elevators, trim work, and signage. Its warm appearance, distinct from the yellow tones of C260 Cartridge Brass, polishes beautifully, enhancing its aesthetic appeal. In industrial settings, C28000 brass is commonly utilized for baffles and tube sheets due to its advantageous properties. At GNEE, we maintain a comprehensive stock of C28000 Muntz Metal sheets, ensuring our customers have access to this versatile material for a variety of projects. Whether for decorative or industrial applications, C28000 Muntz Metal remains a popular choice, combining functionality with visual appeal, making it ideal for both practical and aesthetic uses across numerous industries.
