Precision alloy bars are typically composed of metals like nickel, cobalt, iron, copper, 

 and other elements in specific proportions.  

Common alloys include Invar, Kovar, Mu-metal, Constantan, and Permalloy.

Available in a variety of diameters, typically ranging from 5 mm to over 100 mm, 

 depending on the alloy and specific application. 

 Custom diameters can be produced to meet specific needs.

Used in precision instruments, sensors, magnetic shielding, electrical components,

  and aerospace applications where accurate material behavior is required.  

Applications include aerospace, electronics, medical devices, transformers, and industrial machinery.

High strength, toughness, and resistance to deformation.

  Precision alloy bars offer excellent dimensional stability under both high and low temperature conditions.

Precision alloys are designed for specific thermal applications, such as Invar

  (very low thermal expansion) or Constantan (stable electrical resistance at varying temperatures).

High electrical conductivity (for alloys like Constantan) or controlled 

 resistance (for precise applications like thermocouples, strain gauges).

Precision alloy bars can be cold-rolled, hot-rolled, forged, or drawn to precise diameters. 

 They are also easily machined, threaded, and turned into required shapes for various industrial applications.

Heat treatments such as solution annealing or stress-relieving are commonly 

 applied to precision alloy bars to improve mechanical properties and ensure dimensional stability.

Some precision alloys are weldable, but care is required to control the heat input during 

 welding to prevent material degradation, especially for alloys sensitive to temperature variations.

More expensive than standard carbon steel or non-precision alloys

  due to the high cost of raw materials (nickel, cobalt, etc.) and the precise control required during manufacturing.
