MUNTZ METAL (60 Cu - 40 Zn) Nominal Composition : 60% Cu, 40% Zinc Properties : Excellent hot formability and forge ability for blanking, forming and bending hot forging and pressing, hot heading, upsetting and shearing. C28000 Muntz Metal is 60% copper, 40% Zinc with a trace of iron. If the brass contains over 39% zinc (example – Muntz Metal), it will have a higher strength and lower ductility (at room temperature). C28000 Muntz is commonly used in architectural applications, including decorative panels, elevators, trim work and signage. One side of these sheets has a brushed finish with grain lines running in one direction to mask fingerprints. Brass is commonly used for decorative purposes primarily because of its resemblance to gold. Since it contains a large portion of beta component (zinc), it is stronger, harder, and more rigid than brasses of lesser zinc content. Furthermore, it is relatively less expensive than other brass. Muntz Metal is a type of Brass (alpha-beta brass) also known as yellow metal. Typical applications include signage, architectural applications and condenser plates. The brushed side comes covered with a protective peel-off film. ALG stainless steel offers architects and installers a beautiful slender grain structure, which makes the product highly resistant to dirt and offers the greatest sheet-to-sheet colour uniformity. A lead-free alternative to 485 brass, 464 brass offers good weldability, strength, and wear resistance. Muntz was originally used in nautical applications in the 1800s as a method of protecting the wooden hull of ships. Muntz Metal #4 (C28000) Sheet. C280 hardens rapidly and is stronger and more rigid than brasses with lesser zinc content. It is also a commonly used to make musical instruments due to its high workability and durability. Because of … Industrial applications … Compared to the yellow tones of C260 Cartridge Brass, C280 Muntz has a warmer appearance that readily takes to polishing. This brass metal alloy was invented as an alternative to copper to save on costs. The unique chemical composition of 60% copper and 40% zinc result in a rich color for eye appeal utilized in elevator cabs, wall treatments, molding, wall panels, nameplates, signs, accessories, hardware, lighting, clocks, etc. Known both as Muntz Metal and Yellow Metal, the alloy must be worked hot and is used today for corrosion resistant machine parts. If copper, muntz metal, or zinc is not what you had in mind for metal siding or roofing, ask us about our Architectural Long Grain Stainless Steel (ALG). Muntz Metal is a gold color high bred alloy designed for architectural applications. Muntz metal is an alpha-beta brass which is composed of 60% copper and 40% zinc. It goes by a few different names including Yellow Metal or C280 (C28000). Brass Applications. Like the aluminum bronzes, they combine very … Manganese bronzes are modifications of the Muntz metal-type alloys (60% copper 40% zinc brasses) containing small additions of manganese, iron and aluminum, plus lead for lubricity, anti-seizing and embeddibility. Muntz metal is a highly plastic metal at red heat, making it an ideal choice for pressing, stamping and hot forging. The most common of these is C280 brass sheet, commonly referred to as Muntz Metal. Of all the brasses Muntz has the highest zinc ratio which creates a very interesting patina quite different from pure copper or even other brasses.
