Brass Castings

Brass is an alloy made primarily of copper and zinc. The proportions of the copper and zinc are varied to yield many different kinds of brass. 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 40%.

Lead is commonly added to brass at a concentration of around 2%. The lead addition improves the machinability of brass.

However, significant lead leaching often occurs, even in brass that contains a relatively low overall concentration of lead.

Uses of brass include musical instruments, firearm cartridge casing, radiators, architectural trim, pipes and tubing, screws, and decorative items.

Brass Properties

Brass often has a bright gold appearance, however, it can also be reddish-gold or silvery-white. A higher percentage of copper yields a rosy tone, while more zinc makes the alloy appear silver.
Brass has a higher malleability than either bronze or zinc.
Brass has desirable acoustic properties appropriate for use in musical instruments.
The metal exhibits low friction.
Brass is a soft metal that may be used in cases when a low chance of sparking is necessary.
The alloy has a relatively low melting point.
It's a good conductor of heat.
Brass resists corrosion, including galvanic corrosion from salt water.
Brass is easy to cast.
Brass is not ferromagnetic. Among other things, this makes it easier to separate from other metals for recycling.
