260 brass composition
In its half-hard condition, 260 Brass has a machinability rating of 30 as compared to 360 brass rated at 100. It can become yellower, harder, softer, stronger, or more corrosion-resistant, depending upon its chemical composition. Also known as cartridge brass, Alloy 260 demonstrates good cold working properties. Composition and Properties, The Properties, Production, and Applications of Tin, The Properties and Composition of Monel 400, Brass Alloys and Their Chemical Compositions, Alloy Definition and Examples in Chemistry, The Properties and Applications of Platinum, National Sanitation Foundation International (NSF). Brass is available in a variety of grades, each of which is characterized by the exact material makeup. This elemental composition results in the following material characteristics: Material hardness: B77 (per Rockwell scale) Ultimate tensile strength: 62,000 psi; Yield strength: 52,000 psi; Elongation: 23% Aside from being attractive, brass also is resistant to bacteria, making it that much more useful for fixtures like door handles that multiple people touch frequently. Due to the high zinc contact, it shouldn't be soldered. Many musical instruments also are made of brass because it is a very workable metal and can be formed into the sorts of precise shapes necessary for horns, trumpets, trombones, and tubas. Brass with less than 15% zinc is known as red brass. At Sequoia Brass & Copper, we provide these six grades of brass: Alloy 260.
C260 brass is the most ductile of the brasses and is used in greater quantity than any other copper-zinc alloy. HEAT TREATING. Available Grades of Brass. It also is a particularly strong type of brass. Naval brass, which is used in seawater, actually has 40% zinc, but it also contains 1% tin to reduce dezincification and make it more resistant to corrosion. FORGING Because of its low friction and resistance to corrosion, brass also is popular hardware for plumbing fixtures and other building supplies.
Request Lead often is added to brass to make it softer and thus more malleable. For more information, visit. Brass is a metal alloy that is always made with a combination of copper and zinc.
Copper: 68.5%-71.5% Iron: 0.05% Lead: 0.07% Zinc: 28.5% Other: 0.15%. Some uses, such as figures atop bedposts, are strictly decorative. Fire poles are a common use for 330 brass. Arsenic may be added to make brass more stable in certain environments. For example: Contact with an amine, a compound derived from ammonia, is a common cause of brass corrosion. Be the first to know about special offers, new products and discounts. Items like door handles, lamps, and ceiling fixtures like lights and fans are examples of practical uses that also serve a decorative purpose. The chart below summarizes the composition of a number of commonly used brass alloys: Terence Bell wrote about commodities investing for The Balance, and has over 10 years experience in the rare earth and minor metal industries. 260 Brass has the highest ductility in the yellow brass series. By varying the amount of copper and zinc, brass can be made harder or softer. It is also easily machined and cold formed. UNS C26000, CDA 260, C260, CZ106, ISO CuZn30, 70/30 brass, Cartridge Brass 70%, Safety Data Sheet | Weight Calculator | Mill Test Reports, Purchase 260 Sheet/Plate | 260 Balls | 260 Foil | 260 Round Tube | 260 Shim Stock | Decorative Fittings. Typically used in architecture, electrical parts, fasteners, and ammunition casings. Chemical Composition. It may be polished to a gold-like appearance or given a brushed satin finish.
Shell casings for ammunition also are a popular use for brass, largely because of its low friction. These products can potentially expose you to chemicals including Nickel, Chromium, Lead, Cobalt, Mercury and Beryllium, which are known to the state of California to cause cancer and/or birth defects or other reproductive harm. The most ductile of the yellow brasses, 260 brass also has a good strength, finishing capabilities and corrosion resistance. These instruments, collectively, are commonly known as the brass section of an orchestra. It often is used to make items such as rods and bars. Pipe fittings, nuts, and bolts are often made of brass to take advantage of its characteristics.
For example: There are many different types of brass, each with a slightly different chemical composition.
CDA C26000 brass is produced as a combination of copper and zinc and has the highest ductility in the yellow brass series. Tin can help to make brass stronger and harder. Applications | Specifications | Mechanical and Chemical Data. The National Sanitation Foundation International (NSF) standards require brass fittings containing at least 15% zinc to be resistant to dezincification. COPPER ALLOY 260 BRASS. Fire poles are a common use for 330 brass. 260 brass consists of 68.5–71.5% copper, 28.5–31.5% zinc, up to 0.05% iron, and up to 0.07% lead. Red brass, not surprisingly, is warmer in color than other brasses.
Other metals—such as aluminum, lead, and arsenic—may be used as alloying agents to improve machinability and corrosion resistance. 260 brass should not be used in projects where it will come into contact with acetic acid, hydrochloric acid, nitric acid, or ammonia. 260 Brass forms a thin protective patina, which unlike steel and iron, will not rust when exposed to the atmosphere. Cartridge brass (also referred to as 260 brass and yellow brass) is best known as an ideal metal for shell casings. Free machining brass, also called 360 brass, is relatively high in lead, making it easy to cut and shape. 330 brass is particularly useful in tubing and poles because it is both workable and machinable. The alloy also is susceptible to corrosion through the process of dezincification. Each type of brass has its own name, qualities, and uses. a quote as a guest. The more zinc brass contains, the more it can be impacted by zinc leaching out of the alloy, causing it to become weaker and more porous. Copper alloy 260 Brass is an excellent corrosion resistance metal in most environments and is often referred as Cartride Brass.
330 brass is particularly useful in tubing and poles because it is both workable and machinable. It is most often sold in sheet form and easily formed and worked into desired shapes.

By adding different metals to brass, it is possible to change its properties. It is also easily machined and cold formed. Brass is a popular metal for applications that are both practical and decorative. 260 Brass has poor butt-welding characteristics. 260 brass should not be used in projects where it will come into contact with acetic acid, hydrochloric acid, nitric acid, or ammonia. Adding elements such as tin, arsenic, phosphorus, and antimony can help achieve this effect, as can reducing the amount of zinc to less than 15%. Alro stocks 260 Brass sheet (also known as cartridge brass or yellow brass) - the most popular and economical of the brass alloys. This type of copper is considered by many to be the “work-horse” of all copper alloys.
Naval brass, also called 464 brass, is highly resistant to corrosion and thus ideal for use in seawater. The physical properties of 260 Brass greatly depend on any tempering processes that have been done to the material. Properties of 260 Brass. Cartridge brass (also referred to as 260 brass and yellow brass) is best known as an ideal metal for shell casings. ALL RIGHTS RESERVED.
