alloy. Brass has higher malleability than copper or zinc. In general‚ they have good strength and corrosion resistance‚ although their structure and properties are a function of zinc content. The relatively low melting point of brass (900 to 940°C‚ depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc‚ the properties of the brass can be changed‚ allowing hard and soft brasses. The density of brass is approximately

The Brass Ensemble was held in the Rehearsal Hall at our school of music around 8:00 PM. The venue was a small room with an audience of only around twenty people. The ensemble was a brass quintet made up of two trumpets‚ one horn‚ one trombone‚ and one tuba. The performers sat in a half circle while the director‚ Steven Mahpar‚ stood at the corner of the room. Only two pieces were played‚ yet I was able to truly appreciate the skills showcased by the various performers. Kerry Turner‚ “Kaitsenko”

What is a brass instrument? Before getting into the history of how brass instruments originated and developed it is necessary to be clear on what a brass instrument actually is. A brass instrument is defined as an “aerophone‚” which means it is an instrument where the musician must blow air into the instrument. The musician produces the tone by buzzing the lips into what is generally a cup-shaped mouthpiece. It doesn’t mean that the instrument is necessarily made of brass‚ since instruments that

“Getting Down to Brass Facts: A Roundtable” is an article from the the National Association for Music Education. It is written by Betty Glover‚ Vincent Cichowicz‚ Philip Farkas‚ Abe Torchinsky‚ Michael Hatfield‚ Tom Ervin‚ and John Marcellus. The article is structured by asking a pedagogical question about the instruction of brass instruments‚ followed by responses from each of the seven brass teachers. These teachers include Michael Hatfield (Horn)‚ Abe Torchinsky (Tuba/Euphonium)‚ Tom Ervin (Trombone)

Solder (/ˈsoʊldə/‚[1] /ˈsɒldə/[1] or in USA /ˈsɒdər/[2]) is a fusible metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s). Soft solder is typically thought of when solder or soldering is mentioned‚ with a typical melting range of 90 to 450 °C (190 to 840 °F).[3] It is commonly used in electronics‚ plumbing‚ and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun.Alloys that melt between 180 and 190 °C (360

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon.

Finding the percentage of copper in brass alloy. Introduction This is an investigation to find out how much copper is in a brass alloy. The brass alloy we are experimenting on is called Muntz Metal. Muntz metal is 60% copper‚ 40% zinc and a hint of copper [http://en.wikipedia.org/wiki/Muntz_metal] (accessed 4/10/12). Muntz metal was developed as an alternative to expensive‚ heavy copper. It is comprised of about 60% copper and about 40% zinc‚ with a small amount of iron. The finished product actually
