Also known as chrome-moly steel, this versatile alloy steel is used for a wide range of parts, such as molds and structural supports. It resists fracturing from repeated stress. You can also surface harden it with heat to add wear resistance.

Note: Bars may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as fixture clamps and mounting plates.

With the highest lead content, 360 is the easiest brass alloy to machine. Known as free-machining and free-cutting brass, it handles high-speed drilling, milling, and tapping with minimal wear on your tools. You’ll often see it made into gears, pinions, and lock components.

The lead additive acts as a lubricant, which allows 12L14 carbon steel to withstand very fast machining. These bars are used to fabricate a wide variety of machine parts, such as shaft couplings, studs, and pins. For added wear resistance, they can be surface hardened with heat treating.
