Brass Manufacturing

Forgecast RecyclingRecycling
Forgecast raw materials include a significant percentage of recycled scrap and some primary ingot. Raw materials are carefully weighed into charges and melted using electric induction furnaces. Control on alloy composition is maintained through feedback from spectrographic analysis.

Forgecast's control on alloy composition facilitates ease of manufacture by tailoring alloy to process within the standard specification composition range. Forgecast has developed a number of tailored alloys to suit customer's needs through its team of metallurgists.

Continous Casting produces the highest quality brass extrusion billet. It can achieve high production rates as well as low porosity. The rough skin is removed during the extrusion process.

At Forgecast, each melt is analysed for conformance to chemical composition specifications developed in-house. These specifications are, without exception, well within the UNS specified composition limits.

Having the ability to produce our own brass billet enables us to produce any grade of brass to our customer specifications. These include lead free, DZR and decorative polishing grades.

Extrusion
Forgecast's indirect extrusion process provides high quality forging stock with no risk of "back-end defect" common to direct extrusions or porosity common to concast bar. The extrusion can be tailored to the product, hence assuring quality and minimising process scrap.

 

 

In extrusion, the workpiece is placed in a container and compressed until pressure inside the metal reaches flowstress levels. The workpiece completely fills the container and additional pressure causes it to travel through an orifice and form the extruded product.


Extrusion can be forward (direct) or backward (reverse), depending on the direction of motion between ram and extruded product. Extruded product can be solid or hollow. Tube extrusion is typical of forward extrusion of hollow shapes, and backward extrusion is used for mass production of containers.
