How Steel Is Made | Metal Supermarkets
The Composition of Steel. Steel is an alloy of iron and carbon. It can contain small quantities of silicon, phosphorus, sulfur and oxygen. The carbon content of steel is between 0.08 to 1.5 percent. This makes it harder than wrought iron but not as brittle as cast iron. Steel has a unique balance of hardness, flexibility and tensile strength.
How aluminium is produced
The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer process. It's very efficient but it can only be used on high quality bauxite with fairly low content of admixtures, especially silicon.

What Is a Base Metal? Definition and Examples
A base metal can be a common metal (element or alloy), which relatively low value, that is not used as a basis for currency. Examples include bronze and lead. A base metal can be the primary metal in an alloy. An example is iron in steel. A base metal can be a metal or alloy to which a plating or other coating is applied.
How to Recycle Scrap Copper Wire from Your Job Site
If the copper does enter the soil, it can harm animals' health and restrict local plant diversity. Recycling copper wire keeps landfill levels low and slows the depletion of natural resources. The copper recycling process also uses 85 to 90 percent less energy than mining and processing copper ore. 2.
Guide to Manufacturing Processes for Plastics
With machining, cost per part increases with part complexity. Undercuts, pass throughs, and features on multiple part faces all contribute to increased part cost. Machining processes require allowances for tool access and certain geometries, like curved internal channels, are difficult or impossible to produce with conventional subtractive methods.

Chapter 6 Copper Production Technology
discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
