Precision Alloy Strip
Product Details

Our Precision Alloy Strip, made from high-quality nickel-based and iron-based alloys, is engineered to deliver exceptional mechanical, thermal, and electrical properties. These precision strips offer excellent tensile strength, ductility, and thermal stability, allowing them to endure varying stress and temperature conditions. Manufactured with ultra-precise dimensions and a smooth surface finish, our alloy strips are perfect for demanding applications across multiple industries.
The 3J40 , 3J53, and 3J58 elastic alloys, available in thicknesses of 0.6mm, 0.8mm, and 1.0mm, meet the highest standards for performance and durability, making them essential components for industries like aerospace, electronics, automotive, and medical.
Our Elastic Alloy Precision Strips are tailored for optimal performance in high-precision applications, offering a range of benefits:
High Tensile Strength:
The alloy strips are designed to withstand significant mechanical stress, providing strength and durability in components that are subjected to continuous tension or pressure.
Excellent Ductility:
Despite their strength, the strips maintain superior ductility, allowing them to be easily shaped and formed without compromising their structural integrity.
Thermal Stability:
These alloys exhibit outstanding stability under temperature fluctuations, making them ideal for environments with high thermal cycling or extreme temperatures.
Smooth Surface Finish:
The strips are manufactured with a smooth, precise finish that reduces friction and improves component performance, especially in sensitive applications like connectors and electronic components.
Versatile Application:
These precision strips are highly versatile and can be used across multiple industries, from aerospace to automotive and medical devices. Their reliability makes them a trusted solution in demanding environments.

Our 3J40, 3J53, and 3J58 Elastic Alloys are engineered to meet the exacting demands of several industries:
Aerospace:
Used in critical engine components and other high-performance parts that require both strength and thermal stability to function in extreme conditions.
Electronics:
These strips are perfect for manufacturing connectors, contact springs, and other electrical components that need to perform efficiently in electronic devices, with resistance to thermal cycling.
Automotive:
Automotive applications benefit from the high mechanical strength and ductility of these strips, making them suitable for parts such as sensors, braking systems, and engine components.
Medical Devices:
Used in medical equipment where precision and durability are required, including in surgical instruments, implantable devices, and diagnostic tools.


The 3J40, 3J53, and 3J58 precision alloys are composed of a combination of nickel, iron, and other elements to optimize elasticity, strength, and thermal performance. Specific compositions vary based on alloy type:
Nickel (Ni): Contributes to magnetic properties, strength, and corrosion resistance.
Iron (Fe): Provides strength and thermal stability.
Other elements: Added to enhance elasticity, ductility, and resistance to wear.
Packaging:
The Precision Alloy Strips are packaged securely to prevent damage during transport. The strips are rolled or coiled and wrapped with protective materials, ensuring they arrive in pristine condition.
Shipping:
We offer air and sea freight options to meet your needs. The cost of shipping will depend on the weight, size, and destination of your order. A tracking number will be provided once the order is shipped for easy monitoring.
Lead Time:
Sample Orders: Typically, sample orders are processed and shipped within 7 days after payment confirmation.
Bulk Orders: For larger quantities, processing and shipping typically take 2-3 weeks, depending on the volume and any customization requirements.
