Kovar / Invar / Inconel
High-performance nickel alloys provide the high-strength and structural toughness that make them optimal for a wide selection of industry uses and applications.
Multiple processes can be combined to create dimensionally perfect parts that match your exact design requirements. Our fabrication capabilities include:
Many fabricators choose not to work with Kovar, Invar, or Inconel due to the challenges they present and the cost of these raw materials; however, the added difficulty and expense are not an issue for us. Thanks to our extensive experience with these alloys, we can produce precision parts that match even your most complex designs.
Kovar, Invar & Inconel all exhibit different mechanical characteristics and require unique considerations for accurate fabrication. As highly versatile nickel alloys, these materials are unaffected by extreme temperatures. They can be used in highly caustic environments, retaining their strength in high-temperature applications.
Material properties of Kovar include producing a coefficient of thermal expansion (CTE) similar to glass. Application uses include tube lighting, x-ray tubes, microwave tubes, hermetic sealing for aerospace uses, and solar power technology.
Contact us to discuss your requirements of INvar Material. Our experienced sales team can help you identify the options that best suit your needs.
Petersen Precision uses Kovar for sensor applications for the aerospace industry because it is not affected by heat or cold. It does not shrink or grow, proving to be an ideal material for aerospace applications.
As a low coefficient of thermal expansion nickel-alloy, Invar provides dimensional stability for a variety of applications. Some applications that benefit from Invar include aerospace molds, circuit breakers, magnetic shielding, and temperature regulators.
Ideal for extreme environment applications, Inconel is useful for a wide range of industries. Popular fabrications for Inconel include marine applications such as boat propeller blades, aerospace uses like exhaust pipes, nuclear technology applications such as reactor cores, and more.

Inconel is actually a trademarked word of Special Metals Corporation and it refers to a branch of high nickel superalloys that are resilient to corrosion and oxidation at elevated temperatures and has a high-temperature coefficient of strength. It is predominantly used in the aerospace industry. Machining Inconel is extremely hard because it does not get any softer when the temperature rises. Cold working increases its hardness, making it difficult to machine, whereas metals like stainless steel get softer when the temperature rises, making it easier to cut. When we machine Inconel, its hardness increases non-linearly and wearing the tool disproportionately. So, the cutting tool must be inspected often for excessive wear to ensure quality. The best way to machine Inconel is to start with a &#;solutionized&#; metal. Solutionizing is a heat treatment process that involves heating the material beyond the solvus temperature and soaked until a homogenized solid-solution is formed. It reduces the toughness and the amount of work hardening happening during the process, increasing the tool life. It is also advisable to use Ceramic tools with an aggressive depth of cut but slowly when machining Inconel because it reduces the amount of heat produced in the process. Similarly, peck drilling (repeatedly drilling and retracting the drilling tool) must be avoided for the same reason as above. For cutting plates, water jet cutting does a good job because it doesn&#;t generate heat.
