Product Information

Flat Spring: The model for this type of spring is a flat beam supported either on one or both ends. When supported on one end, it is considered a cantilever spring. Its shape can be rectangular or tapered at the free end. With regards to the cross-section, the geometry is usually rectangular. The deflections for this type of spring are small, only about 25% of the spring length. Common applications of flat springs are electrical switches.

Other Springs Articles These are springs that are designed to deflect under compressive loads. They are the most commonly used and represent 80 to 90% of all springs manufactured. Compression springs geometries can be cylindrical, conical, convex, or concave.

Variable Pitch, Cylindrical Spring: As the name suggests, these are cylindrical springs with varying pitch. This enables the spring to have a varying spring rate, which is also desirable for dynamic applications. Copper-base alloys are important spring materials because of their good electrical properties combined with their good resistance to corrosion. Although these materials are more expensive than the high-carbon and the alloy steels, they nevertheless are frequently used in electrical components and in sub-zero temperatures. Many grades of steel can be hardened and tempered to increase elasticity and resist deformation; however, some steels are inherently more elastic than others: A torsion spring is a mechanical device that stores and releases rotational energy. Each end of the torsion spring is connected to a mechanical component. As the spring is rotated around its axis on one end, the winding of the spring is tightened and stores potential energy... Contract Manufacturing A spring is a flexible machine element that stores mechanical energy when subjected to tensile, compressive, bending, or torsional forces.This section needs additional citations for verification.

Here are just a few of the steel types we create springs from: Copper is known for being a fairly soft and ductile metal, which means that it isn’t nearly so suitable as stainless steel is for bearing heavy loads. On the other hand, when the spring also needs to carry an electrical charge, beryllium copper springs might be able to provide the impact strength and anti-corrosion properties that are just right for the product you have in mind. Hard-Drawn MB Grade, ASTM A227 (0.60-0.70 percent carbon): This grade is used for general purpose springs where cost is the most important factor. Although increased use in recent years has resulted in improved quality, it is best not to use this grade where long life and accuracy of loads and deflections are important. It is available in diameters ranging from 0.031 to 0.500 inch and in some smaller and larger sizes also. The material is available in square sections but at reduced tensile strengths. It is readily plated. Applications should be limited to those in the temperature range of 0 to 250 °F.

Iron in itself is a soft metal. Alloying it with carbon increases its strength and hardness. Its carbon content can range from 0.05 to 0.30% for mild steels and 0.30 to 1.70% for high carbon steels that can still respond to heat treatment. Enumerated below are some of the steels used as spring materials. These are non-helical springs with geometries such as wound strips, cantilever beams, disks, and bars. The cross-section of the spring material is subjected to different types of stresses, mostly combinations of bending and torsional stresses. Extension spring end options - The loop ends of extension springs are normally closed but can be changed to hooks. There are several types of ends for extension springs that include different shaped loops, including V hooks, square, coned, eye, and very small. The standard ends for extension springs are: These are springs that operate with tensile loads. The free length of tension springs is almost equal to the solid length to allow more deflection when stretched. The design of tension springs is the same as compression springs but with more emphasis on the design of end hooks and the initial tension. Tension springs represent about 10% of all springs manufactured. Each of these steel types must be carefully chosen, created and modelled into the spring of your choice, and each subtle adjustment to the make-up of the material must change how we approach the spring-making process, too.When calculated against the pressures it needs to withstand, however, we can figure out how best to solve your problems through the design of our springs. Phosphor Bronze (ASTM B159): Phosphor bronze is an alloy of copper, tin, and phosphorus. This is the most widely used copper-base spring alloy. It has good electrical conductivity coupled with the ability to withstand repeated bending. However, it is are not hardenable by heat treatment. The use of stainless spring steels has increased and several compositions are available all of which may be used for temperatures up to 550 °F. They are all corrosion-resistant. Only the stainless 18-8 compositions should be used at sub-zero temperatures.

Wire baskets are made from a series of wires that are woven together or welded to form a shape of a basket. They can also be defined as containers that are made by use of an openwork pattern of metal... Wire Displays Find sources: "Spring steel"– news · newspapers · books · scholar · JSTOR ( March 2009) ( Learn how and when to remove this template message)Music Wire, ASTM A228 (0.80-0.95 percent carbon): This is the most widely used of all spring materials for small springs operating at temperatures up to about 250°F. It is tough, has a high tensile strength, and can withstand high stresses under repeated loading. The material is readily available in round form in diameters ranging from 0.005 to 0.125 inch and in some larger sizes up to 3⁄16 inch. It is not available with high tensile strengths in square or rectangular sections. Music wire can be plated easily and is obtainable pretinned or preplated with cadmium, but plating after spring manufacture is usually preferred for maximum corrosion resistance. Wire shaping is a complex method that encompasses a wide range of dimensions, forms, and textures. The technique of creating a usable product by wire bending and shaping is known as custom wire forms... Wire Forming Flat springs come in a variety of shapes, sizes and materials. Commonly used materials for flat springs include carbon steel, stainless steel, brass, copper, phosphor bronze, and beryllium copper. Lee Spring offers advanced capabilities and a wide variety of options for your flat spring manufacturing needs such as; advance quality control systems, regulatory expertise including RoHS, REACH and DFARS CAD assisted product design, in-house prototype production services and global supply chain network. Oil-Tempered HB Grade, SAE 1080 (0.75-0.85 percent carbon): This material is similar to the MB grade except that it has a higher carbon content and a higher tensile strength. It is obtainable in the same sizes and is used for more accurate requirements than the MB Grade, but is not so readily available. In lieu of using this material it may be better to use an alloy spring steel, particularly if a long fatigue life or high endurance properties are needed. Round and square sections are obtainable in the oil-tempered or annealed conditions. Barrel (Convex) and Barbell/Hourglass (Concave) Springs: These are helical springs with double cone geometries. They have the same advantages as that of conical springs.

Music Wire (ASTM A228): Music wire is used to make carbon steel springs that have high tensile strength, a high elastic limit, and high fatigue resistance. Its superior mechanical properties come from being cold worked and drawn through a series of dies. Music wire’s surface is coated with a tin solution during cold working to produce an excellent surface finish for secondary processes such as electroplating. Music wire is used to make small springs subjected to high loads and cyclic conditions, with high temperature music wire used in foundries, heat treating, and refractories where there are extremely hot internal temperatures. Springs are a flexible machine elements that store mechanical energy when subjected to tensile, compressive, bending, or torsional forces. When the spring is deflected, it stores energy and, at the same time, exerts an opposing force. The relationship between the amount of deflection and the force exerted depends on the characteristics of the spring. The most common form is a cylindrical, helical spring with a constant pitch. This type of spring is a round wire spooled into a cylindrical form. It is commonly seen in vehicle suspension systems, engine valves, dampers, and so on.Cylindrical Springs: This is the most common type of spring. The pitch on these springs is equal. Since the pitch and coil diameters do not change along the length of the spring, the spring rate is constant. a b c Oberg, Erik, and F D. Jones. Machinery's Handbook. 15th ed. New York: The Industrial Press, 1956. 1546–1551. Print. Springs can be classified according to the type and nature of the force acting on the spring. These can be further categorized by their geometry, form, and construction. The most common form of spring is a helical spring, which is made from a wire with a circular cross-section. Springs with special constructions exist for absorbing heavier loads or for fitting in mechanisms with small clearances. Helical Compression Springs: Coil springs called compression springs can store mechanical energy when they are compressed. These open-coiled, helical springs provide resistance to compressive loading. When these springs are... Extension Springs Hard-drawn (ASTM 227): These are the cheapest of the spring materials, with inferior qualities compared to music wire and oil-tempered steels. Hard-drawn wires are also cold worked, similar to music wires, but the drawing process used is less controlled than that of music wires.
