What Type of Spring Materials Can KENENG Supply?
As a spring manufacturer in China, we can produce springs in various materials. Including stainless steel, carbon steel, copper, alloys, etc.
Alloy steel springs are made from steel enhanced with alloying elements such as chromium, vanadium, or molybdenum to improve strength, durability, and resistance to wear and fatigue of the spring. Known for their excellent load-bearing capacity and resilience under extreme conditions, these springs are widely used in automotive, aerospace, industrial machinery and heavy-duty applications. Their superior mechanical properties make them ideal for environments requiring high stress tolerance and long service life.
Monel/hastelloy/Inconel springs are engineered from premium nickel-based alloys, offering exceptional resistance to corrosion, oxidation, and extreme temperatures. These springs maintain their strength and reliability in harsh environments such as chemical processing, marine, oil and gas, and aerospace applications.
They are made from high-quality stainless steel grades, offering excellent strength, flexibility, and resistance to rust, suitable for applications in marine, medical, food processing and industrial equipment. With superior longevity and consistent performance, stainless steel springs are ideal for both indoor and outdoor use where durability and hygiene are essential.
Titanium or tianium alloy springs are lightweight, with high-strength, known for their exceptional corrosion resistance and ability to perform in extreme temperatures. Offering an excellent strength-to-weight ratio, they are ideal for aerospace, marine, medical, and high-performance industrial applications. These springs maintain reliable elasticity and fatigue resistance while significantly reducing overall system weight, making them the preferred choice for harsh environments.
Copper and brass springs are highly conductive, corrosion-resistant, valued for their excellent electrical and thermal properties, and widely used in electronics, marine, and decorative applications. Copper springs offer superior conductivity and flexibility, making them ideal for electrical contacts and precision instruments, while brass springs provide added strength, wear resistance, and aesthetic appeal. These springs combine durability with reliable performance in both functional and design-focused uses.
Carbon steel springs are known for their excellent tensile strength and durability. Made from high-carbon steel, they offer reliable performance and resilience under high stress, suitable for automotive, industrial machinery, agricultural equipment, and general mechanical applications. With proper coating or treatment, they provide a balance of strength, flexibility, and affordability for a wide range of uses.
