Product Parameters

Leaded Brasses:

Used for their high machinability and atmospheric corrosion resistance. The machinability of brass is increased by the addition of lead because it acts as a microscopic chip breaker and tool lubricant. The leaded brasses are used for copper base screw machine material. The alloys have excellent machinability, good strength and corrosion resistance. Lead can be added to any brass to increase machinability and provide pressure tightness by sealing the shrinkage pores. There are low, medium and high leaded brasses, with lead contents up to 3.5%. The lead brasses are used for architectural hardware, general purpose screw machine parts, screws, valves, fittings, bearings and specialty fasteners.

Tin Brass:

Used for its increased corrosion resistance and somewhat higher strength than straight brass. This family of alloys is made with zinc contents ranging form 2 to 40% zinc, and 0.2 to 3.0% tin. Tin reduces susceptibility of the high zinc brass to dezincification. Dezincification is the selective leaching of zinc from the brass leaving a porous copper structure.

Description

ADVANTAGES OF BRASS ALLOYS

Brass alloys supply many advantages within a manufacturing environment:

• The wide availability of zinc and copper help keep brass alloys comparatively cost-effective.
• Brass both casts and machines easily, helping manufacturers to control production costs better.
• Today metallurgists can manipulate the composition of brass alloys to elicit certain desirable properties in a metal component. For instance, manufacturers use carefully-created brass alloys to obtain strength, corrosion resistance, heat conductivity, wear-resistance, and the ability to tolerate extensive machining.
• Brass possesses warm, rich colors, contributing to its popularity as a decorative metal, too.
• Brass alloys display a durable lifecycle providing solid value. These materials usually maintain shape well over the course of time.

• Manufacturers can create ornate patterns in the surface of brass, permitting the creation of intricate details more cost-effectively in a single extrusion. This capability often contributes to reduced production times and lower cost requirements.
