| Property | Precision Alloy Steel Coil and Strips |
| Material Composition | These alloys are typically composed of high-purity elements such as nickel, iron, cobalt, and chromium, with precise control over the balance of each component. Common alloys include Invar, Kovar, and Constantan. |
| Thickness | Precision alloy strips are generally thin, ranging from 0.1 mm to 3 mm, depending on the alloy and specific application. |
| Applications | Used in precision instruments, electronic components, sensors, transformers, and automotive parts where high accuracy and consistency in material behavior are required. |
| Mechanical Properties | High strength, dimensional stability, and excellent resistance to deformation. Precision alloy strips are often used where thin, flexible materials with excellent mechanical stability are needed. |
| Thermal Properties | These alloys are designed for specific thermal applications, such as low thermal expansion (e.g., Invar), or high conductivity (e.g., Constantan). |
| Electrical Properties | High electrical conductivity (for alloys like Constantan) or controlled resistance (for precise applications such as strain gauges and thermocouples). |
| Magnetic Properties | Certain precision alloys, like Mu-metal, are designed for high magnetic permeability and are used for shielding sensitive equipment from magnetic fields. |
| Forming & Fabrication | Precision alloy strips can be cold-rolled, hot-rolled, or even electroplated for added surface properties. They can be easily bent, stamped, or formed into intricate shapes while maintaining dimensional accuracy. |
| Heat Treatment | Precision alloy strips can undergo heat treatment such as annealing or stress-relieving to ensure dimensional stability and optimal mechanical properties. |
| Welding & Joining | Some precision alloys are weldable, but care must be taken to control welding conditions to avoid material degradation (especially for alloys with low melting points). |
| Examples of Alloys | Invar (36% Fe-Ni), Kovar (Fe-Ni-Co), Constantan (Cu-Ni), Mu-metal |
| Cost | Precision alloy strips are typically more expensive due to the high level of material control and purity required. |
| Common Standards | ASTM A-240, ASTM B-637, ASTM B-553, ASTM F-15, AMS 5525 |
