Nickel Alloy 2J09, 2J10 (Vicalloy 1), 2J11 (AFK584) refers to a series of precision alloys designed for specific industrial applications. These alloys are typically used in applications requiring a combination of magnetic properties, corrosion resistance, and mechanical strength. Here's an overview of these nickel-based alloys:
The composition of these alloys varies slightly depending on the specific grade, but they generally contain:
High Magnetic Permeability
These alloys exhibit excellent magnetic properties, making them suitable for use in magnetic circuits and other applications requiring high permeability.
Corrosion Resistance
Their nickel content ensures good resistance to oxidation and corrosion in various environments, including humid and mildly acidic conditions.
High Strength and Toughness
These alloys maintain mechanical integrity under stress and are suitable for structural components subjected to mechanical loads.
Thermal Stability
The alloys are stable at moderate temperatures and can retain their magnetic and mechanical properties under thermal cycling.
Machinability
They are relatively easy to machine and fabricate into thin sheets, plates, and strips, which are often used in industrial applications.

Industrial Applications
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. | |
Common Standards | 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.
