Types of Metal Spring

Compression

By far the most common type of spring is the compression spring. Found in countless applications, compression springs, as the name suggests, are those familiar coiled springs that provide resistance when compressed by an external force. Compression creates the mechanical energy required to carry a load.

Extension

Extension springs, also referred to as tension springs, operate on the principle of tension. In contrast to compression springs, extension springs tightly wound helical coils have no pitch between them. They are designed with hooks or loops on both ends of the spring that are attached to other components within a mechanical assembly.

Torsion

Torsion springs are a type of flat spiral coil-shaped spring used for applying torque or rotational energy. Unlike compression or extension springs that require a linear force to push or pull, torsion springs utilize torque. A torsion spring rotates on its axis when a load is applied or resisted—its mechanical energy is stored and released via that rotational force or twisting action.

Constant Force

Unlike traditional helical-wound springs, constant-force springs differ in design and function. They exert a consistent linear force or torque that remains constant over a large range of motion. Thus, constant-force springs are found in applications that typically require some kind of counterbalancing or retraction mechanism.

Benefits of Metal Spring

Energy Storage

Springs excels at storing energy. When you compress or stretch a spring, it holds onto that energy. It’s like a miniature battery, ready to release its power when needed.

Shock Absorption

Springs are natural shock absorbers. They can absorb a sudden impact and spread it out over time, protecting other parts of a machine or structure from damage.

Force Control

Springs allow precise force control in many applications. By choosing the correct spring rate, engineers can fine-tune how much force is applied in a system.

Space Efficiency

Springs can pack a lot of functionality into a small space. They can provide force, movement, or energy storage without taking up much room.

Versatility

Springs come in countless shapes and sizes. This variety means there’s likely a spring solution for almost any mechanical challenge.

Common Metal Spring Materials

Carbon Steel Springs
Iron on its own is a relatively soft metal. However, alloying it with carbon enhances its strength and hardness.

Alloy Steel
Alloy steels contain additional elements like chromium, vanadium, phosphorus, and silicon. Each of these elements enhances specific properties of the steel, such as increased strength, hardness, and machinability.

Stainless Steels
Stainless steel is an iron alloy that contains at least 10.5% chromium, which is the minimum amount required to impart corrosion resistance to the metal.

Non-Ferrous Alloys
These alloys feature a base metal other than iron, with common base metals including copper and nickel. Copper alloys are known for their high electrical and thermal conductivity, excellent corrosion resistance, and good machinability.

FAQ

Q: What are metal springs used for?

A: Energy Storage and Release: Springs can store strain energy and, when compressed or stretched, return to their original shape when released. This ability allows springs to be used in electronic components, vehicles, home appliances, industrial machinery and other fields.

Q: How long do metal springs last?

A: Here is spring's life expectancy on average: Standard Cycle Springs: 10,000 cycles. High Cycle Springs: 25,000 cycles. Highest Cycle Springs: 50,000 cycles.

Q: What is the strongest metal spring?

A: Chrome vanadium
Chrome vanadium is the strongest and toughest of all spring steels and has excellent fatigue properties. Music wire is a high-carbon steel alloy with good fatigue life and can handle high stresses but is brittle. Stainless steel is a corrosion-resistant material that can withstand harsh environments and temperatures.

Q: Why springs are usually made of steel and not copper?

A: For manufacturing springs, steel is preferred. Steel is more elastic than copper because the value of the Young modulus is higher for steel than for copper. A material's yield strength is the maximum stress that can be sustained by the material without crossing the elastic limit.

Q: What metal is best for making springs?

A: High Carbon Steels
The properties of this material make it sought-after for springs, as it can offer great hardness levels and resistance to wear and tear. Hard drawn wires for low-stress applications come at a low cost, while higher tensile materials are best suited for high-stress applications and are more expensive.
