| Property | Precision Alloy Steel Strips | Precision Alloy Steel Sheets |
| 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. | Similar to strips, precision alloy sheets are made from carefully controlled compositions, often with low expansion coefficients or specialized magnetic properties, such as Invar or Mu-metal. |
| Thickness | Precision alloy strips are generally thin, ranging from 0.1 mm to 3 mm, depending on the alloy and specific application. | Precision alloy sheets are thicker than strips, typically ranging from 0.5 mm to several millimeters, depending on mechanical and thermal property requirements. |
| Applications | Used in precision instruments, electronic components, sensors, transformers, and automotive parts where high accuracy and consistency in material behavior are required. | Commonly used in industries such as aerospace, electronics, and medical devices for components like structural parts, enclosures, and sensitive instrumentation that require controlled mechanical properties and dimensional accuracy. |
| 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. | High tensile strength, excellent flatness, and precision in dimensions. These sheets offer stable mechanical properties under both high and low temperature conditions. |
| Thermal Properties | These alloys are designed for specific thermal applications, such as low thermal expansion (e.g., Invar), or high conductivity (e.g., Constantan). | Similar to strips, these sheets are designed for specific thermal behaviors, such as low expansion or high-temperature stability, depending on the alloy (e.g., Invar, Mu-metal). |
| Electrical Properties | High electrical conductivity (for alloys like Constantan) or controlled resistance (for precise applications such as strain gauges and thermocouples). | Precision alloys in sheet form may also have controlled electrical resistance, especially for applications in sensitive electronics or electrical components. |
| Magnetic Properties | Certain precision alloys, like Mu-metal, are designed for high magnetic permeability and are used for shielding sensitive equipment from magnetic fields. | Similar to strips, magnetic alloys like Mu-metal sheets are used for shielding in sensitive equipment to control or eliminate external magnetic interference. |
| 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. | Precision alloy sheets can be cold-rolled, heat-treated, laser-cut, or stamped. They are suitable for both complex shapes and applications requiring high dimensional tolerance and material consistency. |
| Heat Treatment | Precision alloy strips can undergo heat treatment such as annealing or stress-relieving to ensure dimensional stability and optimal mechanical properties. | Heat treatments like solution annealing or stress-relief are common for precision alloy sheets to improve properties such as strength, stability, and resistance to thermal expansion. |
| 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). | Precision alloy sheets can be welded or brazed, although welding requires careful control of heat to avoid compromising the alloy's properties. |
| Examples of Alloys | Invar (36% Fe-Ni), Kovar (Fe-Ni-Co), Constantan (Cu-Ni), Mu-metal | Invar, Mu-metal, Kovar, Constantan, Permalloy |
| Cost | Precision alloy strips are typically more expensive due to the high level of material control and purity required. | Precision alloy sheets are also expensive, as they require precise manufacturing and composition control. Their cost is higher than standard steel or non-precision alloys. |
| Common Standards | ASTM A-240, ASTM B-637, ASTM B-553, ASTM F-15, AMS 5525 | ASTM A-240, ASTM B-637, ASTM B-553, AMS 5525 |
1: What is precision alloy?
Precision alloys refer to special alloys with high purity, uniformity and stability. They are usually used to manufacture parts or components that have extremely strict size, shape and performance requirements. They have special physical properties (such as magnetic, electrical, thermal, etc.) and chemical properties to meet specific engineering requirements.
