Basics of... Brass, Bronze, Copper, Nickel & Iron
Brass and Bronze - Many forms available. Copper alloys developed to exhibit someof the characteristics of copper, with added strength, machinability and formability
Brass and Bronze - Exhibits a unique combination of properties, including high electrical andthermal conductivity and good resistance to corrosion.
Nickel - Good corrosion resistance, easy to weld. Excellent for marine andchemical processing applications.
| Alloy Type | Description |
|---|---|
| Brass | |
| 260 | Basic copper zinc alloy that combines good fabrication and electrical characteristics |
| 353 | The addition of lead to this alloy makes it easier to machine, saw and mill |
| 360 | A commonly used brass that is excellent for machining |
| 464 | Excellent corrosion resistance and strength. Commonly used in contact springs,fuse clips, terminals and connectors. |
| Bronze | |
| 220 | A commonly used brass that is excellent for machining |
| 316 | Commonly used for cable clamps and many screw machine products |
| 510 | Spring tempered to resist fatigue. Used for springs, hardware andthrust bearings. |
| 655 | Often used in marine environments because of its good corrosion resistance fromsalts, acids and alkalais. |
| 660 | Excellent impact and wear resistance. Excellent for bearings and bushings. |
| 954 | A popular aluminum bronze that has excellent strength and hardness. Good for usein pressure bearing surfaces. |
| SAE 841 | Oil impregnated alloy that can be machined for close tolerances, used for selflubricating bearings and bushings |
Cast Iron - Also known as "gray iron". Has moderate strength and goodmachinability. Responds well to fast heat treating. Commonly used for valve bodies,bushings and a variety of moderate strength parts and fittings.
Ductile Iron - Stronger and more pliable than cast iron. Strength is similar to steel.Excellent hardenability makes ductile iron a good choice for gears, bearings, camsand other high strength parts.
| Alloy Type | Description |
|---|---|
| Copper | |
| 102 | High purity, high conductivity with virtually no oxygen content. Malleable andeasy to weld |
| 110 | High conductivity, good corrosion resistance and excellent ductility. More than99.3% pure copper. For a variety of general purpose applications. |
| 122 | Excellent for heating systems, oil burners and liquid transfer applications |
| 145 | Tellurium Copper Alloy 145 is an exceptional copper alloy. Similar properties toAlloy 110 Copper, Alloy 145 offers users a combination of free cutting formachining and drilling and also high conductivity. Can also be hot forged. |
| 172 | Non-sparking and the highest strength copper alloy. Frequently used in aircraftbearings, drilling equipment, springs and terminals. |
| 182 | High conductivity and excellent strength are combined in this chromium copperalloy. Primary uses are resistance welding, electrodes, welding tips and holders. |
| 1751 | Highest electrical and thermal conductivity of all copper alloys. |
| Nickel (Monel) | |
| 400 | Composition is 65% nickel, 32% copper and 3% iron. Also known as Monel.Resists hydrofluoric and hydrochloric acids. |
| Cast Iron | |
| Dense grain, consistent density and hardness, heat treatable and wear resistant,similar to ASTM A48, Class 83 iron, tensile strength is 40,000 psi, oversized topermit finishing. | |
| Ductile Iron | |
| Composition is 65% nickel, 32% copper and 3% iron. Also known as Monel.Resists hydrofluoric and hydrochloric acids. |
