Brass Forgings and Copper Forgings

Brass Forgings and Copper Forgings

Today, manufacturers frequently forge brass and copper alloys. Although the specific type of forging depends upon the particular composition of the metal, generally these alloys lend themselves to cold, warm and hot forging techniques. The process of forging enables these metals to display strength and superb physical properties. During forging, manufacturers typically use a set of dies to form and shape metal into desired dimensions.

Forging readily permits the creation of copper bars, rods, wires, sheets and more. Some common copper alloys include copper nickel, naval brass, aluminum bronze, chromium copper and chromium zirconium copper. Most brass alloys include both copper and zinc. The level of zinc will influence the forging process and the strength and ductility of the final products.


Properties of Copper and Brass

Today, manufacturers enjoy access to a myriad of different copper and brass alloys. They may select individual metals to use in copper and brass alloy forgings based upon their properties and intended applications.

Some metals, such as silver, exhibit superb antibacterial characteristics. Copper displays antimicrobial properties against some types of bacteria. These properties may influence a manufacturer’s selection of alloys. Copper maintains excellent electrical conductivity. Copper and brass typically exhibit high electrical and thermal conductivity, high ductility, excellent joining and plating properties, and corrosion resistance. Non-magnetic and non-sparking, these metals work well for machining purposes also.

Copper And Copper Alloys

Although vulnerable to sulfides, copper and copper alloys generally display resistance to corrosion caused by steam. Tough, highly ductile and malleable, manufacturers can draw wire, form tubes and conduct deep drawing and spinning using copper.

Brass And Brass Alloys

Many brass alloys include both copper and zinc. Zinc enhances the strength and versatility of brass alloys, which may benefit from heat treatments such as tempering and annealing in order to reduce susceptibility to stress corrosion cracking.


Benefits of Copper Forgings and Brass Forgings

Copper and brass forgings offer distinct advantages to manufacturers. Some of the general benefits include:
•    superior mechanical characteristics
•    high density;
•    dimensional accuracy;
•    repeatability;
•    excellent surface finishes

Forging will augment and enhance many of the intrinsic properties of brass and copper. For instance, forging may increase the working of these metals. Work may occur both during forging and also during the process of rod extrusion. The net result of multiple working usually involves increases in the strength and the impact and abrasion resistance properties of brass and copper.

Additionally, higher leak resistance may occur as forging density increases. Fewer variations in dimensions also occur during extensive forging processes.

Maximum cost savings often result when manufacturers rely on mass production of copper and brass forgings. Grappling with specific design issues may warrant small production runs of copper alloy forgings. For example, these types of limited runs may permit manufacturers to address close tolerances, non-symmetrical shapes and leak integrity issues cost-effectively before seeking larger production runs.


Cold, Warm and Hot Forging

Today, manufacturers produce brass and copper forgings using a variety of brass and copper alloys. Foundries rely upon cold, warm or hot forging processes. The desired qualities of the finished metal part usually determine the types of production processes employed.

Cold Forging of Brass And Copper

Manufacturers can use cold forming to work with most alloys of brass and copper. The ability to use cold forging depends upon the chemical composition of the alloy, and the metal’s annealed properties. Both reliable and cost-effective, cold forging may improve a metal part’s hardness and ductility. The use of cold forging usually involves cost savings. It may increase the toughness of a component, and permit the creation of excellent dimensional accuracy and a high surface quality in a finished part. Highly productive production runs sometimes use this process, which may include activities such as cold drawing, cold heading, bending and more in order to produce diverse shapes.

Warm Forging of Brass And Copper

Brass and copper alloys display versatile properties. Manufacturers often seek to shape and work these materials in a variety of ways. During the process of warm forging, a manufacturer uses an elevated temperature to forge copper and brass. The temperature range remains lower than during hot forging, but does rise to a level above room temperature. In general, utilizing warm (as opposed to hot) forging assists tooling life, individual part tolerance ranges and sometimes, surface finishes.

Hot Forging of Brass and Copper

A process called “hot forging” enables the production of many brass and copper parts. In this process, metals undergo plastic deformation at high temperatures. Manufacturers use this process to forge complex shapes unavailable through the processes of cold or warm forging. Hot forged copper and brass alloys display increased ductility. They also typically demonstrate an excellent surface quality. The process of hot forging proves especially useful in the creation of custom-designed brass and copper forged parts.
