High-Carbon Valve Spring Steel (ASTM A230): These are high-carbon steels with uniform quality and temper. They are drawn the same way as oil-tempered steels, but their heat treatment is more controlled. As the name suggests, they are used as valve springs in automotive and aircraft engines which require corrosion resistance, fatigue resistance, and good performance at high temperatures.

Lee Spring offers a wide selection of metal springs for sale. Metal springs are available in a wide range of material options, characteristics, and price ranges. Selecting the right metal spring material for a particular application is an important step when selecting a metal spring. Some considerations related to metal springs are operating temperature, regulatory requirements and corrosion resistance. 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. Many grades of steel can be hardened and tempered to increase elasticity and resist deformation; however, some steels are inherently more elastic than others: 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.Tubular spring steel is used in the landing gear of some small aircraft due to its ability to absorb the impact of landing. To proceed with the design, initial values must be assumed. Typically, the type of material is initially selected. The objective of the design then becomes finding the geometry of the spring that can operate under the applied force and deflection. Wire dimensions, coil length, and the number of active coils are assumed initially for trial calculation. These values are correlated through tables and charts from spring design handbooks or manufacturer datasheets. The values are verified if the theoretical stress experienced by the spring with trial dimensions is within the maximum allowable stress of the material operating at a given type of service. If the theoretical stress calculated exceeds the maximum allowable stress, another set of trial dimensions is used. 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.

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 Closed and Square:The last coil of a closed and square compression spring is closed, making it possible to stand on end on a flat surface. The pitch of the end is reduced to form one dead coil.Primarily used in electrical applications, copper springs can be vital to your final product. Titanium Springs Extensive Network of Approved Suppliers (Raw Materials, Special Processes and Production Components) A coil spring is an elastic element made of metal or heavy plastic in the form of curls or ringlets of round wire or cord that is wrapped around a cylinder. The winding of a coil spring can be loose or tight in a helical shape depending on the application for which it is made... Compression Springs
