Brass and bronze ingot making
- Brass and bronze ingot making
The brass and bronze ingot making industry in this country has its mid 1850's roots in the start of the Industrial Revolution. During this historical rapidly growing time of inventions, parts made from brass or bronze were highly sought after. Parts made from these copper-based alloys have unique mechanical and chemical properties. Ingots, brick shaped metal bars weighing approximately 25 pounds, are melted by brass and bronze casting foundries and then poured into molds to produce the desired part. Typical examples of cast brass parts are marine propellors, valves, faucets and architectural hardware.
Originally, these ingots were produced from primary metal as scrap dealers were few and far between in the early days. As an example, one of the most popular alloys used early on, is CDA 836 which is known as "red brass" or 85-5-5-5. Initially this alloy was called "ounce metal" because one pound of copper and one ounce each of tin, lead and zinc when melted together produced an alloy consisting of 85% copper 5% tin 5% lead and 5% zinc. Most of the early brass and bronze ingot producers were formed and founded by European immigrants just as their scrap recycling dealer counterparts were.
