Forging | Copper and Brass Forgings – RENYI CASTINGS

1. Copper Manufacturer — Renyi Castings and Brass Forgings | Bronze Forgings made from copper based alloys offer a number of advantages over products made by other processes. Dimensional precision is greater than by casting, working the alloys develops improved strength, and overall cost is modest. Zero draft forgings are possible, though not always practical. However, minimum draft forgings are being produced. Minimum draft capability is independent of alloy composition; alloys that can be forged by conventional means can be forged to minimum draft angles approaching 1°. Cored forgings are common and provide near-net shape parts with minimal waste. Copper based alloys whose major alloying element is zinc are designated brasses. Those whose major alloying element is other than zinc are designated bronzes, such as silicon bronze and aluminum bronze. Those alloys with very high copper content, typically 98% or more, are generally designated “coppers”, such as beryllium copper. Copper based alloys are designated by a six- character alphanumeric system. The first character is C, indicating the copper base. The next five are numeric characters. The first numeric indicates the major group, and the remaining four, designate the alloys within the group.Copper and brass forgings are quality parts, comparing favorably in material integrity, dimensional tolerance and surface finish with products made using other major metalworking processes. As a result of hot working, forged materials have superior density and freedom from flaws. Forming under heat and pressure in precise closed dies produces dimensional accuracy- always repeatable, part to part and lot to lot. Excellent surface finish with a clean, lustrous appearance is readily available with copper and brass forgings.

2. This material will help design engineers and purchasing departments maximize the utility and cost advantages inherent in the specification of copper and brass forging. It reviews competitive processes, compare their advantages and disadvantages with forging. A tabular guide to the tolerances commonly specified for forgings of different types is included. An extensive glossary of terms used in the industry and information required for ordering are included to improve communication between user and supplier. Copper and Brass Forging offer a number of outstanding advantages over parts produced by other manufacturing processes. These advantages result from the inherent properties of copper and copper alloys plus additional improvements in mechanical and physical properties imparted by the forging process.
