Old Yellow Brass

Old Yellow Brass

Muntz metal, also called Yellow Metal, variety of the alloy brass consisting of 60 percent copper and 40 percent zinc, named after the English businessman George F. Muntz, who patented it in 1832. Muntz metal must be worked hot. It is used to make machine parts that require resistance to corrosion. What Is Brass? Brass is not a pure metal like gold – it is an alloy of 67% copper and 33% zinc (the percentages may vary). It looks similar to gold and has a similar yellowish color, and it is sometimes used in decorations and jewelry. Due to the presence of copper, brass shows antimicrobial and germicidal properties.

Perhaps the best way to distinguish between brass and bronze is through their color. Brass usually has a muted yellow shade, much like dull gold, which makes it a good material for furniture and fixtures. Bronze, on the other hand, looks almost always a reddish brown.
