Brass Materials Properties

Brass is a versatile copper-zinc alloy that comes in various subtypes based on the specific composition of its constituents.

Brass C260

Brass C360

Brass C260 Properties

Brass C260, also known as Cartridge Brass or 70/30 Brass, is a widely favored alloy with a composition of 70% copper and 30% zinc. Its unique blend of properties makes it a top choice for various industries, from ammunition manufacturing to architectural fittings and musical instruments.

Tensile Strength, Yield (MPa)	Fatigue Strength (MPa)	Elongation at Break (%)	Hardness (Brinell)	Density (g/cm^3)
75	90	68	53	8.53

Brass C360 Properties

Brass C360, also known as Free-Cutting Brass or Free-Machining Brass, is a popular choice in industries where efficient and precise machining is a priority. Its composition, comprising approximately 61.5% copper, 35.5% zinc, and 3% lead, grants it unparalleled ease of cutting and shaping, making it a go-to material for intricate and complex designs.

Finishes and Post-Processing Options

As machined (standard): Brass is readily machined, so its freshly machined surface will often exhibit an attractive finish even without any extra attention. Therefore, it is often possible to leave the part in a machined state. Surface finish is further improved with additional finishing passes.

Polishing: Polishing is a popular finish for brass, as it brings out the lustrous shine of the metal. It can range from a bright mirror-like finish to a satin or brushed finish, depending on the level of abrasion used.

Sandblasting: Sandblasting brass involves using fine abrasive particles to etch the surface, creating a matte finish or adding texture for a distinctive appearance.
