WIELAND C24000

Wieland C24000, also known as low brass, is an 80Cu-20Zn alloy. Low brass, named for its relatively low zinc content, is a choice of many design engineers for applications where strength and formability are required. Due to its higher zinc content (compared to red brass), low brass develops a beautiful antique brass color when chemically treated, making it ideal for many decorative or architectural applications. This datasheet provides information on composition, physical properties, and elasticity. It also includes information on corrosion resistance as well as casting and heat treating. Filing Code: Cu-927. Producer or source: Wieland Rolled Products NA (formerly Olin Brass).

ANSONIA ALLOY C24000

Ansonia alloy C24000 is a 20% Zn alloy with the trade name of low brass. It is often used in musical instruments and ornamental trim. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on forming, heat treating, machining, and joining. Filing Code: CU-774. Producer or source: Ansonia Copper & Brass Inc.

Medical Problems of Brass Instrumentalists: Prevalence Rates for Trumpet, Trombone, French Horn, and Low Brass

This study examined the medical problems of musicians who primarily perform on a brass instrument. Data for this study (n = 739) were extracted from the University of North Texas Musician Health Survey data set. Subjects were included if they indicated either trumpet, trombone, French horn, or low brass as their primary instrument. Prevalence rates for one or more musculoskeletal problems were determined for the whole group and by instrument. For those subjects who reported problems at specific sites, average severity levels were derived from responses to a five-point grading scale. Additional prevalence rates for non-musculoskeletal problems were established for the whole group and by instrument. About 60% of the brass musicians reported having one or more musculoskeletal problems. The trombone group reported the highest rate (70%), followed by French horn and low brass (62%), and then trumpet (53%). Results suggest unique physical performance requirements and risks across the four main brass instrument groups and that future studies should examine each brass instrument group individually.

Relationships among Selected Variables in the South Dakota All-State Band Auditions

The purpose of this study was to examine the effects of school enrollment, distance to audition site, sex of auditionees, and instrument type on the results of the 1992–97 South Dakota all-state band auditions. Results include the following: (1) total audition scores were better for students from larger schools and for those who traveled a shorter distance to the audition; (2) female students' scores were significantly better than those of male students, but there was no significant difference in the percentages of successful auditions between males and females; (3) scores differed significantly between instrument groups, with flutes and double reeds receiving the best scores, followed by saxophones, trumpets and French horns, low brass and string basses, and clarinets; and (4) the variables of distance to audition site, instrument group, and sex accounted for 11% of the variance in total audition scores.

COPPER ALLOY No. C43500

Copper Alloy No. C43500 is a tin containing brass. It has strength and ductility comparable to low brass (80% copper, 20% zinc). It has excellent cold workability. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on forming, heat treating, machining, and joining. Filing Code: Cu-565. Producer or source: Copper and copper alloy mills.
