ANSI / ABMA Grade | American National Standards Institute (ANSI) or American Bearing Manufacturers Association (ABMA) standard grades for balls or spheres use measures for sphericity or roundness deviation and ball diameter variation or tolerance and surface roughness tolerance for determination of ball grade. DIN and ISO 3290 provide similar European standards for ball grade specification along parameters similar to ABMA grade specifications. AMBA Grade 3 has a spherical deviation of 3 millionths of an inch (0.000003). AMBA Grade 5 has a spherical deviation of 3 millionths of an inch (0.000005). AMBA Grade 10 has a spherical deviation of 10 millionths of an inch (0.000010). ABMA Grade 25 has a spherical deviation of 25 millionths of an inch (0.000025). AMBA Grade 50 has a spherical deviation of 50 millionths of an inch (0.000050). AMBA Grade 500 has a spherical deviation of 500 millionths of an inch (0.0005). AMBA Grade 1000 has a spherical deviation of 1000 millionths or 1 thousandth of an inch (0.001). American Bearing Manufacturers Association (ABMA) was formerly known as Anti Friction Bearing Manufacturers Association (AFBMA), so some manufacturers will still reference AFBMA grades. | ||

Aluminum / Aluminum Alloy (UNS A) | Aluminum and aluminum alloys are lightweight, non-ferrous metals with good corrosion resistance, ductility, and strength. Aluminum is relatively easy to fabricate by forming, machining, or welding. This metal is a good electrical and thermal conductor. Aluminum is also useful as an alloying element in steel and titanium alloys. Aluminum alloys are versatile metals with applications in almost every industrial and commercial segment. | ||
Carbon Steel | Plain carbon steels are ferrous alloys based on iron, carbon and small levels of other alloying elements such as manganese or aluminum. Carbon steels include soft, non-hardenable low carbon or mild steels such as 1020, as well as hardenable high carbon steels such as 1095. Steel alloys are used in a wide variety of applications in almost every industrial segment. Mild steels and low carbon steels can be fabricated easily by machining, forming, casting and welding. | ||
Cobalt / Cobalt Alloy | Cobalt and cobalt alloys are non-ferrous magnetic alloys with high strength and toughness, excellent corrosion and oxidation resistance, and high temperature strength. Cobalt can also be magnetized. Cobalt's properties result in the use of cobalt alloys in jet engine super-alloy components, prosthetic devices, magnets, and cutting tool binders. Cobalt is also a useful alloying element in tool, maraging and other alloy steels. | ||
Copper / Copper Alloy | Copper and copper alloys are non-ferrous metals with excellent electrical and thermal conductivity as well as good corrosion resistance, ductility and strength. Copper alloys are relatively easy to fabricate by forming, casting or machining. Pure copper is more difficult to weld, cast or machine. Brass, tin bronze, leaded brass, beryllium copper and zirconium copper are examples of copper alloys. Copper is also useful as an alloying element in aluminum alloys and powder metal based iron alloys. Copper is a versatile metal with applications in many industrial and commercial segments. Copper's high electrical conductivity (100% IACS) make it extremely useful in electrical and electronic applications. | ||
Nickel / Nickel Alloy | Nickel and nickel alloys are non-ferrous metals with high strength and toughness, excellent corrosion resistance, and superior elevated temperature properties. Nickel can also be magnetized. Nickel's properties result in the use of nickel alloys in jet engine super-alloy components, corrosion resistant chemical process equipment (valves, piping, and pumps), magnets and electrical resistance alloys, and heating elements. Nickel is also a useful alloying element in stainless, tool, maraging and other alloy steels. | ||
Refractory / Reactive (UNS R) | Refractory and reactive metals include boron (B), tungsten (W), tantalum (Ta), molybdenum (Mo), niobium (Nb) / columbium (Cb), zirconium (Zr), hafnium (Hf), thorium (Th), vanadium (V), chromium (Cr), cobalt (Co), rhenium ( ), and titanium (Ti). Refractory metals and alloys are metals with melting points above ~1750 C (~ 32000 F). Refractory metals include tungsten tantalum, molybdenum, niobium, and zirconium. Refractory metals are used in high temperature, structural, electrical, and other specialty applications. Reactive metals combine readily with oxygen at elevated temperatures to form very stable oxides. Titanium, zirconium, and beryllium are considered reactive metals. Finely divided reactive metals can react explosively with oxygen and are often added to rocket fuels or combustible mixtures. A highly stable oxide film formed on the alloy surface provides protection against further oxidization or corrosion at low to moderate temperatures. Reactive metals can become embrittled if there is too much interstitial absorption into the lattice of oxygen, hydrogen, and nitrogen. | ||
Stainless Steel | Stainless steels are highly corrosion resistant, ferrous alloys that contain chromium and/or nickel additions. There are three basic types of products: austenitic stainless steels, ferritic and martensitic stainless steels, and specialty stainless steels and iron superalloys. Austenitic stainless steels (AISI 300 / 200 Series) are highly corrosion resistant, ferrous alloys that contain chromium and nickel or manganese additions. Generally, austenitic stainless steels are more corrosion resistant than ferritic or martensitic stainless steels. Annealed austenitic stainless steels are non-magnetic. Cold working is used to harden austenitic stainless steels because these alloys do not respond to conventional quench and temper hardening processes. Ferritic and martensitic stainless steels are highly corrosion resistant, ferrous alloys that contain chromium and/or carbon additions. Ferritic stainless steels are soft, easy to form metal alloys. Cold working is used to harden ferritic stainless steels because these alloys do not respond to conventional quench and temper hardening processes. Ferritic stainless steels are formed to fabricate mufflers and other sheet metal components that require good corrosion resistance. Martensitic stainless steels can be hardened by a conventional quench and temper operation. Martensitic stainless steels are used for knife blades, tooling or other applications that require good corrosion resistance combined with higher hardness and wear resistance. Specialty stainless steels and iron superalloys are highly corrosion resistant, ferrous alloys containing chromium, nickel or other alloying additions to provide high strength or heat resistance. Duplex and precipitation hardening stainless steels belong in this category. | ||
Titanium / Titanium Alloy | Titanium and titanium alloys are non-ferrous metals with excellent corrosion resistance, good fatigue properties, and a high strength-to-weight ratio. Titanium's properties result in the use of titanium and titanium alloys in aircraft or air frame parts, jet engine super-alloy components, corrosion resistant chemical process equipment (valves, piping, and pumps), prostheses or medical devices, and marine equipment. | ||
Tool Steel | Tool steels are wear resistant, ferrous alloys based on iron and carbon with high levels of alloying (hardenability and property modifying) elements such as chromium, molybdenum, tungsten and vanadium. Specific tool steel grades are available for die or cold work, hot work, high speed and shock resistance applications. Tool steel alloys are used in a wide variety of applications that require wear resistance. They are difficult to fabricate in their hardened form and are usually EDM-machined or ground to achieve the tolerances required for tooling applications. EDM is an acronym for electrical discharge machining, a process that can cut small or odd-shaped angles, intricate contours and cavities in extremely hard steels and exotic metals. | ||
Tungsten Carbide (WC) | Tungsten carbide (WC) materials are compounds of a tungsten metal and carbon. Metal carbides are also known as hard metals. Metal carbides have high hardness and high hot hardness which makes them useful for cutting tools, forming dies and other wear applications. Metal carbides often use a cobalt, nickel or intermetallic metal bond between grains (cemented carbides), which results in increased toughness compared a pure carbide or ceramic. | ||
Specialty - Ferrous Alloy | Other miscellaneous ferrous alloys have specialized or proprietary compositions or properties. Examples include maraging steels, high strength low alloy (HSLA) steels, and iron-based superalloys. | ||
Specialty - Nonferrous | Other miscellaneous nonferrous metals or alloy grades. | ||
