Exotic alloys - Lee Spring explain what they are and when to use them

Materials with high alloy content, known as super alloys or exotic alloys, offer enhanced performance properties including excellent strength and durability, and resistance to oxidation, corrosion and deforming at high temperatures or under extreme pressure. Because of these properties, super alloys make the best spring materials for demanding working conditions, which can be encountered across various industry sectors, including the Automotive, Marine and Aerospace sectors as well as oil and

REDUX™ Wave Springs from Lee Spring – an enabling technology

Lee Spring REDUX™ wave springs offer a way of performing a spring function in minimal spaces – even perhaps where no other spring could work effectively. Typically, REDUX wave springs occupy just 30-50% of the compressed height space of the conventional round wire springs, yet they offer more deflection with the same load specifications. This not only helps to save space in the applications but also reduces the production costs,

Lee Spring address extreme conditions of varying types

Lee Spring address the issues of extreme conditions through use of specialist materials and while low or high temperatures may take our minds toward expensive exotic alloys, extreme conditions vary to a wide extent such as being highly sensitive to magnetic, electrical or chemical conditions.

Lee Spring – a worldwide supply chain in metric and imperial

Lee Spring have found that for ease of specification and sourcing, design engineers often select their measurement units to match local standards, or otherwise those used by the design department or the manufacturing facility. This simple choice at an early stage can make life a lot easier for all concerned and reduce unforced errors of transcription – saving time, saving costs. So, to make life even easier and ensure engineers/buyers have

Which Spring is right for my application?

As market leaders in ex-stock industrial springs, Lee Spring offer some guidance to engineers who are either designing assemblies, developing for production or concerned with installation/maintenance and find that the choice predominantly covers: Compression Springs are for push applications which compress when a force is applied, and have either closed ends (where the two end coils of the spring are closed and touching) or open ends (where the end coils are

A brief guide to spring design - by Chris Petts at Lee Spring

Whether selecting a catalogue spring or specifying a custom item Chris Petts, M.D. at Lee Spring suggests that it is always worth considering the following factors: Principles of spring design Hooke’s Law is a principle of spring design relating to Load and Deflection. It states that a restoring force due to a spring is proportional to the distance the spring is deflected and acts in the opposite direction. Another principle of
