2019年1月27日 · 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.

Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, [1] but copper typically has the larger proportion, generally 66% copper and 34% zinc.

2024年9月14日 · Basic modern brass is 67% copper and 33% zinc. However, the amount of copper may range from 55% to 95% by weight, with the amount of zinc varying from 5% to 45%. Lead is commonly added to brass at a concentration of around 2%. The lead addition improves the machinability of brass.

2023年7月9日 · The chemical composition of the material can lead to variations in its color, hardness, texture, strength, and resistance to corrosion. Typically, brass exhibits a warm and golden hue. The incorporation of a 1 percent manganese content in brass results in a transformation of its color to a pleasant warm chocolate-brown hue, whereas the ...

2019年9月2日 · Brass is a metal alloy that is always made with a combination of copper and zinc. By varying the amount of copper and zinc, brass can be made harder or softer. Other metals—such as aluminum, lead, and arsenic—may be used as alloying agents to improve machinability and corrosion resistance.

2025年1月17日 · Brass typically contains 55% to 95% copper and 5% to 45% zinc by weight. This range allows for significant variation in the alloy’s properties. In addition to copper and zinc, small amounts of other elements, such as lead, iron, aluminum, and tin, are sometimes added to enhance specific characteristics.

2025年1月16日 · Composition of Brass. Brass, a versatile alloy, is mainly made of copper and zinc. These variations are tailored to meet specific needs, with copper content typically ranging from 60% to 90% and zinc from 10% to 40%. ... For applications in corrosive environments like marine settings or chemical plants, 70/30 brass offers enhanced corrosion ...

2025年1月28日 · Brass is an versatile and widely used metallic compound in chemistry, is an alloy of copper and zinc. Its composition can be varied to create different types that possess unique properties such as hardness, malleability, and color.

2005年4月25日 · Brasses are alloys of copper and zinc. They may also contain small amounts of other alloying elements to impart advantageous properties. Brasses have high corrosion resistance and high tensile strength. They are also suited to hot forging. Free machining grades of brass set the standard for machining, by which other metals are compared.

2024年12月13日 · Here’s a summary of the chemical composition of Brass Alloy 360: The unique chemical composition of Brass Alloy 360 results in excellent strength, corrosion resistance, and machinability, making it highly versatile for various industrial applications.
