Abrasion-Resistant AR400 Carbon Steel: This material withstands abrasion and wear from sliding and gouging because of its uniform hardness and the addition of elements such as nickel and molybdenum.

Impact-Resistant A516 Carbon Steel: Even in low temperatures, A516 resists breaking upon impact. Also known as pressure vessel quality steel (PVQ).

General Purpose 1074/1075 Spring Steel: Often used for springs and shims, this material is easier to form and bend than 1095 spring steel, but it has a lesser degree of bounce-back when heat treated.

Wear-Resistant 1095 Spring Steel: A high carbon content gives this spring steel good wear resistance and hardness for demanding applications. Use it to fabricate parts that will be used under continual stress, such as spring clips and washers.

Multipurpose 4140/4142 Alloy Steel: Also known as chrome-moly steel, this versatile material is used for many parts, such as gears, axles, shafts, collets, and dieholders.

High-Strength A514 Alloy Steel: A high yield strength makes A514 suitable for structural applications and supporting heavy loads. Also known as high-strength low-alloy (HSLA) steel, this alloy is treated for enhanced strength and hardness.

Easy-to-Weld 4130 Alloy Steel: Its carbon content is low enough for good weldability but high enough to give this steel abrasion and impact resistance. 4130 is often used for gears, fasteners, and structural applications.

Stress-Resistant 5160 Alloy Steel: Similar to spring steel, this material handles repeated cycles of stress without breaking.

Stainless Steel Alloys

Multipurpose 304 Stainless Steel: From cookware to chemical-processing equipment, 304 is the most commonly used stainless steel.

High-Temperature Multipurpose 309 Stainless Steel: Often used in heat exchangers and furnaces, 309 provides good corrosion resistance at elevated temperatures because of its high levels of chromium and nickel.

High-Strength Multipurpose 301 Stainless: Steel able to withstand repeated stress and wear, 301 provides the strength required for applications such as springs and fasteners.

Economy-Grade 430 Stainless Steel: Use 430 for decorative and light-duty applications, rather than outdoors or in extreme temperatures.

Weldable 321 Stainless Steel: When an application requires welding, 321 is the stainless steel of choice because its titanium content preserves corrosion resistance around the welded area.

Super-Corrosion-Resistant 316 Stainless Steel: Molybdenum gives 316 excellent corrosion resistance for use in a variety of marine and chemical-processing applications.

Strengthened Corrosion-Resistant A286 Stainless Steel: Combining the corrosion resistance of 316 with titanium for added strength, A286 is often used to make fasteners and engine components.

Ultra-Conductive Copper (Alloy 101): Also known as oxygen-free high-conductivity (OFHC) or oxygen-free electronic (OFE) copper, this ultra-pure (99.99%) copper is good for high-temperature apps such as terminal lugs & wire connectors.

Machinable Copper (Alloy 145): Also known as tellurium copper, Alloy 145 offers good machinability, making it a great choice for creating high-speed screw machine products requiring conductivity and corrosion resistance.

High-Strength Copper (Alloy 182): Also known as RWMA Class 2 chromium copper, this chromium-copper alloy is stronger, harder, and more wear resistant than pure copper.

Ultra-Machinable Brass (Alloy 360): The standard by which copper, brass, and bronze machinability is measured, Alloy 360 is also known as free-machining brass. Its lead content prevents successful welding but does provide lubrication to enable high-speed machining such as drilling, milling, and tapping.

Ultra-Machinable Brass (Alloy 353): Commonly called engraver’s brass, Alloy 353 has machinability approaching that of Alloy 360 with a lower lead content. Well suited for forming applications such as knurling and threading.

Ultra-Machinable Brass (Alloy 385): Also known as architectural brass, Alloy 385 is easy to machine, with nearly the same machinability as Alloy 360.

Formable Brass (Alloy 260): This simple copper-zinc alloy offers the best formability of all the brasses, as well as good corrosion resistance and machinability.

Weldable Naval Brass (Alloy 464): This weldable alloy offers good corrosion resistance for saltwater and steam applications, as well as improved strength thanks to a high zinc content.
