How is lead-free brass made?

Lead-free brass is typically made by using alternative materials to replace the lead that is typically present in traditional brass alloys. Commonly used alternatives include bismuth, silicon, and manganese.
The manufacturing process for lead-free brass is similar to that of traditional brass. It involves melting the base metals, typically copper and zinc, together at high temperatures until they form a homogenous alloy.
However, during the manufacturing process, the lead-free additives are added to the alloy to replace the lead. The amount of the alternative additive used will depend on the specific application and desired properties of the brass.
Once the lead-free brass alloy is formed, it can be shaped into various products using casting, extrusion, or forging methods. The finished product will have similar physical properties to traditional brass, but without the health and environmental risks associated with lead.
