Control and witness hot forging working processes through manufacturing procedures and on-site metallographic observation to ensure that the final product meets the customer’s specific requirements.

Advantages of Forgings

Forgings 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.

In making a forging, the metal is worked twice under tremendous pressures-first during rod extrusion and then during forging. 

The double working under pressure compacts the metal and produces a very dense and refined grain or fiber structure.

The tensile strength of the parts is thereby increased, and resistance to impact and abrasion is enhanced.

The dense non-porous forged metal permits the designer to specify thinner sections without the risk of leaks due to flaws and voids.

Often the thinner forged parts result in lighter weight and lower piece cost compared to other forming processes.

A forging produced in a steel die with close tolerances offers several advantages. Overall part dimensions are held closer than in sand casting.

Dimensions show minimum variation from part to part and permit automatic chucking and handling in subsequent operations.

The precise designs on the die surface can produce sharp impressions on the forging surface, which is not economical with other forming processes.

Mass production of forged parts lends itself to maximum savings. However, smaller quantities of copper alloy forgings can also prove economical when specific design problems must be solved. 

These problems include leak integrity, close tolerances, high strength with low weight, and non-symmetrical shape.

Copper and Brass Forgings

Renyi have established ourselves as one of the prominent manufacturers and suppliers of Forgings for various industries. These are made using premium grade raw material in the manufacturing process sourced from reputed vendors. We can also customize our gamut as per the specification detailed by the clients.

We have gained huge accolades from our clients for our excellent quality range of Brass Copper Forgings for many products. Moreover, these are manufactured using superior quality materials procured from reliable vendor.

Our range of products finds a wide application across various industries for their comprehensive features like high purity, high tensile strength, corrosion resistance and high durability. Additionally, our range of products is offered at very reasonable price in the market.


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.

Copper and Brass

This material will help design engineers and purchasing departments maximize the utility and cost advantages inherent in the specification of brass and copper forgings. It reviews competitive processes, comparing their advantages and disadvantages with forging. A 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.
