| Property | Precision Alloy Steel Sheets | |
| Material Composition | 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 sheets are thicker than strips, typically ranging from 0.5 mm to several millimeters, depending on mechanical and thermal property requirements. | |
| Applications | 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 tensile strength, excellent flatness, and precision in dimensions. These sheets offer stable mechanical properties under both high and low temperature conditions. | |
| Thermal Properties | 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 | Precision alloys in sheet form may also have controlled electrical resistance, especially for applications in sensitive electronics or electrical components. | |
| Magnetic Properties | 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 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 | 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 | 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, Mu-metal, Kovar, Constantan, Permalloy | |
| Cost | 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. | |

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.
