No, brass is an alloy (chemical solution) of copper and zinc.

Aluminium also causes a highly beneficial hard layer of Although copper and zinc have a large difference in In October 1999 the California State Attorney General sued 13 key manufacturers and distributors over lead content. It is not considered a compound, although the mixture has different chemical properties due to the arrangement of the atoms. Brass is similar to bronze, another alloy containing copper that uses tin in place of zinc; both bronze and brass may include small proportions of a range of other elements including arsenic, lead, phosphorus, aluminum, manganese, and silicon. For stainless, add some chromium. The tin addition suppresses zinc leaching.Other phases than α, β and γ are ε, a hexagonal intermetallic CuZnBrass has sometimes historically been referred to as "yellow copper".The compositions of these early "brass" objects are highly variable and most have zinc contents of between 5% and 15% wt which is lower than in brass produced by cementation.During the later part of first millennium BC the use of brass spread across a wide geographical area from By the first century BC brass was available in sufficient supply to use as Brass was produced by the cementation process where copper and zinc ore are heated together until zinc vapor is produced which reacts with the copper.

232, 245, in Zarnecki, George and others; Rehren, T (1999) "The same...but different: A juxtaposition of Roman and Medieval brass making in Europe" in Young, S.M.M. The lead and arsenic significantly suppress the zinc loss.

(ed.) (ed.) Uses of brass include musical instruments, firearm cartridge casing, radiators, architectural trim, pipes and tubing, screws, and decorative items. (2003) "Early Brass in the ancient Near East" in IAMS Newsletter 23 pp.

for Brass has higher malleability than bronze or zinc.

Common names for brass alloys may be misleading, so the Unified Numbering System for metals and alloys is the best way to know the composition of the metal and predict its applications. By using ThoughtCo, you accept our

(eds) Thornton, C.P and Ehlers, C.B. Gilmore, G.R. Actually, it’s neither.

Bayley 1990, p. 10.Craddock, P.T. The dist In laboratory tests, state researchers found the average brass key, new or old, exceeded the Also in California, lead-free materials must be used for "each component that comes into contact with the wetted surface of pipes and An example of DZR brass is the C352 brass, with about 30% zinc, 61-63% copper, 1.7-2.8% lead, and 0.02-0.15% arsenic. 192–3, Craddock and Eckstein 2003, p. 228 Brass has long been a popular material for decoration for its bright gold-like appearance, e.g. There is good archaeological evidence for this process and Brass made during the early Roman period seems to have varied between 20% to 28% wt zinc.Little is known about the production of brass during the centuries immediately after the collapse of the These places would remain important centres of brass making throughout the The cementation process continued to be used but literary sources from both Europe and the In Europe a similar liquid process in open-topped crucibles took place which was probably less efficient than the Roman process and the use of the term tutty by Eventually it was discovered that metallic zinc could be However, the cementation process was not abandoned, and as late as the early 19th century there are descriptions of Brass making in Renaissance and post-medieval EuropeBrass making in Renaissance and post-medieval EuropeSan Francisco Superior Court, People v. Ilco Unican Corp., et a.

Brass is any alloy consisting primarily of copper, usually with zinc.In some cases, copper with tin is considered a type of brass, although this metal historically has been called bronze.This is a list of common brass alloys, their chemical compositions, and the uses of the different types of brass. 27–36Montero-Ruis, I and Perea, A (2007) "Brasses in the early metallurgy of the Iberian Peninsula" in La Niece, S. Hook, D. and Craddock, P.T. The letter is followed by five digits.

Burnett, A and Preston K. (1980) "Hellenistic copper-based coinage and the origins of brass" in Craddock, P.T. Brass is an alloy of copper and zinc, in proportions which can be varied to achieve varying mechanical and electrical properties.

Here's a comparison between them: Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. It’s an alloy, a mixture of metals. Working as a metallurgist, I have rarely come across the term "mixture" with regard to metals, othern than powdered metals. 222–4. (No.
