Understanding Kovar Alloy Properties and Machining Challenges
If you’re considering kovar machining services, it’s important to first understand what makes this alloy special and why it requires expert handling. Kovar is a unique iron-nickel-cobalt (Fe-Ni-Co) alloy prized for its stable thermal expansion, which closely matches that of borosilicate glass. This makes it ideal for hermetic sealing components used in electronics, aerospace, and medical devices.
Core Composition and Characteristics
Kovar typically contains about 29% nickel, 17% cobalt, and the rest iron. This specific blend gives it these key traits:
- Low thermal expansion: Maintains dimensional stability under temperature changes.
- Excellent corrosion resistance: Suitable for harsh environments.
- Good mechanical strength: Can withstand stress in high-performance applications.
- Superior glass-to-metal sealing ability: Ensures airtight, reliable seals in telecom and medical electronics.
Key Machining Challenges and Solutions
Despite its great properties, Kovar isn’t the easiest metal to machine. Some challenges include:
- Hardness and toughness: Can wear down cutting tools quickly.
- Burr formation: Requires precision to prevent rough edges.
- Thermal sensitivity: Cutting generates heat that might cause warping or distortion.
At XTJ Precision Mfg, we tackle these challenges by using specialized CNC milling and Swiss machining techniques. Our advanced tooling reduces tool wear, while controlled heat treatment and coolant systems keep the workpiece stable. This helps achieve competitive CNC tolerances, ensuring every part fits perfectly in assemblies.
Benefits of Factory Direct Pricing
Choosing factory direct Kovar machining services offers clear cost advantages:
- Lower material and setup costs: No middlemen or added fees.
- Transparent pricing: Understand exactly what you’re paying for.
- Better scalability: Whether you need a custom Kovar prototype or high-volume production, factory pricing adapts to your needs.
This approach lets you maximize return on investment, balancing quality and price effectively. For more insights into cost drivers, check out our guide on how much is the cost per CNC machining part.
Understanding these aspects upfront helps you get the best results with Kovar alloy machining while staying within budget.

Breaking Down Factory Pricing for Kovar Machining
When it comes to factory direct Kovar machining pricing, there are a few key cost drivers to keep in mind:
- Material Costs: Kovar alloy is a specialty low expansion metal, so its price is higher than common metals. Bulk buying helps reduce costs, which is why factory prices tend to be more competitive.
- Setup and Tooling: Machining Kovar requires precise CNC milling setups and sometimes specialized tooling to handle its thermal stable alloy properties. Initial setup costs can be significant, especially for custom parts or prototypes.
- Production Volume: Larger orders spread out tooling and setup costs, lowering the per-piece price. XTJ offers scalable runs from prototyping to high volume, meaning you pay less as you order more.
XTJ Precision Mfg uses a transparent pricing model with clear quotes upfront. For example, a small batch of hermetic sealing components might include a setup fee plus material and machining time, while a larger production run benefits from reduced unit costs. This approach helps customers clearly see where their investment is going.
Choosing XTJ also means better return on investment due to:
- High yield rates from tight CNC tolerances on Kovar parts, reducing waste and rework
- Efficient workflow that shortens lead times and shipping costs
- Factory direct quotes cut out middlemen, saving you money and improving delivery reliability
